## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This patent application claims the benefit of the filing date of the U.S. Provisional Application No. 60/330,208, filed Oct. 17, 2001, the disclosure of which is hereby incorporated by reference in its entirety.


FIELD OF THE INVENTION
The present invention relates to the field of chemical manufacture and in particular, cosmetics and personal care products.
BACKGROUND OF THE INVENTION
Formulation of personal care and cosmetic products, such as shampoos, conditioners, sunscreen lotions, lipstick products, mascara, and the like, presents a number of challenges. The feel and look of such products should appeal to consumers. For example, it may be desirable for certain of such products to have a non-greasy skin feel, good skin-spread ability, pleasant smell, and so on. At the same time, the cosmetic and personal care products typically include a variety of necessary ingredients. For the formulator, the necessity of obtaining physical characteristics that appeal to consumers coexists with the necessity of incorporating the necessary functional ingredients in the product.
Personal care and cosmetic products typically include chemical compounds that function as emollients. The emollients contribute to the desired skin feel, but often serve other purposes in the formulation as well.
Emollients, which often constitute a major portion of the product formulation, can also significantly influence the dissolution/dispersion of the functional ingredients in the formulation. For example, the sunscreen products include sunscreen active ingredients that are preferably uniformly dissolved or dispersed in the formulation. However, certain commonly used sunscreen active ingredients exhibit poor solubility/dispersability in the product formulations. Any non-uniform distribution of the active ingredient may lead to a reduction in the quality and performance of the sunscreen product. Likewise, many cosmetic and personal care products contain fragrances, which also may exhibit poor solubility/dispersability, making it difficult to incorporate the fragrances in the product formulation. Therefore, the emollient component of the product formulation should not negatively effect the solubility of the functional ingredient(s), and, preferably, should help solubilize or disperse the functional ingredient(s) in the formulation.
Certain aromatic esters are presently used as ingredients in the personal care and cosmetic products. For example, Croda Corporation of Parsippany, N.J., manufactures and sells alkoxylated esters of aromatic dicarboxylic and tricarboxylic acids, which are disclosed in U.S. Pat. Nos. 5,693,316, 5,597,555, 5,455,025, and 5,302,377. The aromatic compounds disclosed in these patents are esters of aromatic carboxylic acids, and thus contain an ester carboxylic group 




in which the aromatic nucleus (Ar) is connected to the carbon atom of the ester carboxylic group, and the fatty alkyl group (R) is connected to the ester oxygen atom (Oe) of the ester carboxylic group. Thus, the overall order of connection to the ester carboxylic group in these esters may be illustrated as: 




Although these esters are excellent emollients for sunscreens and cosmetics, the need still exists for new compounds useful as ingredients for personal care and cosmetic products to provide additional options to the product formulators. Specifically, the need exists for emollient compounds that improve the solubility of active ingredients in the formulation while contributing to a pleasant skin feel.
SUMMARY OF THE INVENTION
In accordance with one preferred aspect, the present invention addresses these needs by providing esters of aromatic alkoxylated alcohols and fatty carboxylic acids, which are excellent additives for cosmetic and personal care products. For example, they may be used as emollients, solubilizers/diluents and/or thickeners. Preferably, the esters of aromatic alkoxylated alcohol and fatty carboxylic acid are compounds that include an aromatic nucleus (Ar), an alkoxy spacer (Alk), an ester carboxylic group 




and a fatty alkyl group (R), with the aromatic nucleus being connected to the ester oxygen atom (Oe) of the ester carboxylic group via the alkoxy spacer and the fatty alkyl group being attached to the carbon atom of said ester carboxylic group. The overall order of connection to the ester carboxylic group(s) in the esters of the invention may be illustrated as 




Thus, the structure of the aromatic esters of the invention is substantially different from the structure of the esters disclosed in U.S. Pat. Nos. 5,693,316, 5,597,555, 5,455,025, and 5,302,377.

The esters of aromatic alkoxylated alcohols and fatty carboxylic acids preferably have one or two ester carboxylic groups. The fatty alkyl group (R) of the esters of the invention preferably contain from 1 to 39 carbon atoms. The preferred esters of aromatic alkoxylated alcohols and fatty carboxylic acids have a skin spread factor of less than 10 or a viscosity of less than 20,000 cps. Various preferred esters of aromatic alkoxylated alcohols and fatty carboxylic acids are also disclosed herein.
In accordance with another preferred aspect, the invention provides a personal care or cosmetic product composition that includes a) at least one ester of alkoxylated aromatic alcohol and fatty carboxylic acid present in the amount of from about 0.1% to about 99% by weight of the composition and b) at least one functional ingredient present in the amount of from about 0.1% to 60% by weight of the composition. The functional ingredients may include active ingredients and additional ingredients. Preferred compositions are sunscreen product formulations and antiperspirant products. Thus, especially suitable active ingredients are sunscreen active ingredients and antiperspirant active ingredients.
In one preferred embodiment of this aspect of the invention, the composition further includes at least one cyclomethicone compound present in the amount of from about 1% to 99% by weight of the composition.
In accordance with yet another preferred aspect, the invention provides a method of improving the protection of human or animal skin or hair from radiation by providing a sunscreen product formulation including a sunscreen active ingredient and at least one ester of alkoxylated aromatic alcohol and fatty carboxylic acid, and topically applying such sunscreen product formulation to the hair or skin.
In accordance with yet another preferred aspect, the invention provides a method of improving the protection of human or animal skin or hair from perspiration by providing a antiperspirant product formulation including an antiperspirant active ingredient, at least one cyclomethicone compound and at least one ester of alkoxylated aromatic alcohol and fatty carboxylic acid, and topically applying such antiperspirant product formulation to the hair or skin.


DESCRIPTION OF THE PREFERRED EMBODIMENTS
For the purposes of the present invention, various terms used herein are defined as follows. A “compound” is a distinct chemical substance having molecules of the same chemical structure. A “compound” is not a mixture of molecules having different chemical structures. A “composition” may include one compound or a mixture of compounds. An “alkyl” group is a group that includes a chain of carbon atoms. An alkyl group may terminate in alkyl or non-alkyl functionality and may connect to the rest of the molecule through alkyl or non-alkyl functionality. In the compounds described herein, and consistent with the definitions set forth above, the alkyl groups, when present, may be substituted or unsubstituted, straight chain or branched, saturated or unsaturated. The term “fatty” in reference to alkyl groups and/or carboxylic acids is not intended to indicate origin. Rather, the term “fatty” is used in reference to any group that provides the esters of the invention with hydrophobic contribution. Purely for the purpose of illustration, the methyl group of the acetic acid is a fatty group within the meaning of the invention. The substituents of the alkyl groups described herein, if present, may include lower alkyl, which are alkyl groups containing from 1 to 8 carbon atoms, such as methyl, ethyl, n-propyl, i-propyl, and butyl; halogenated lower alkyl, such as trifluoromethyl, perfluoroethyl, chloromethyl, and dichloromethyl; arylalkyl, such as benzyl; alkylaryl, such as p-methylbenzyl; halo, such as fluoro, chloro and bromo; carboxy, such as acetoxy and ethylcarboxy; alkylcarboxy, such as acetoxymethyl and acetoxyethyl; arylacetoxy, such as acetylbenzyl; hydroxy; alkoxy, such as methoxy, ethoxy and propoxy; and alkylhydroxy, such as hydroxymethyl and hydroxyethyl.
The “alkoxylated aromatic alcohols” include compounds having one, two or more hydroxyl groups —OH, which are referred to herein as the hydroxy groups. The alkoxylated aromatic alcohols containing a single hydroxy group are referred to as monohydroxy alkoxylated aromatic alcohols. Purely for the purposes of illustration, monohydroxy alkoxylated aromatic alcohols include compounds having a single group of the structure  CH2CH2O5H and no other hydroxy groups in the molecule. The alkoxylated aromatic alcohols containing two hydroxy groups are referred to as dihydroxy alkoxylated aromatic alcohols. Purely for the purposes of illustration, dihydroxy alkoxylated aromatic alcohols include compounds having two groups of the structure  CH2CH2O5H and no other hydroxy groups in the molecule, as well as compounds having one group of the structure  CH2CH2O5H one group of the structure —CH2—OH, and no other hydroxy groups in the molecule.
The term “an ester of alkoxylated aromatic alcohol and fatty carboxylic acid,” which is used in defining the compounds of the invention, is the common name for the class of esters compounds. The esters of the invention are defined by the nature of the groups connected to the ester group. It should be understood that the esters of the invention may be produced by any methods known in the art, rather than exclusively from the alkoxylated aromatic alcohols and the fatty carboxylic acids. The esters of the invention include several groups of compounds, such as monoesters of monocarboxylic acids and monohydroxy alkoxylated aromatic alcohols, monoesters of monocarboxylic acids and dihydroxy alkoxylated aromatic alcohols, and diesters of monocarboxylic acids and dihydroxy alkoxylated aromatic alcohols. While certain other types of compounds are not excluded, the polyesters and oligoesters are not the esters of alkoxylated aromatic alcohol and fatty carboxylic acid within the meaning of the invention. For example, the products of the condensation reaction between a dicarboxylic acid (or a dicarboxy derivative of a dicarboxylic acid) and a dihydroxy alkoxylated aromatic alcohol are not the esters of alkoxylated aromatic alcohol and fatty carboxylic acid within the meaning of the invention.
The preferred esters of alkoxylated aromatic alcohol and fatty carboxylic acid have the structure 




where R′ is an organic moiety that contains at least one aromatic nucleus RN; R′′ is a fatty alkyl group; and  ALK—O is an alkoxy spacer.

The aromatic nucleus RN may contain from 6 to 20 carbon atoms exclusive of substitution. Nuclei RN having 6 and 10 carbon atoms are preferred. Non-limiting examples of the aromatic nuclei RN are benzene, naphthalene and anthracene nuclei, which contain 6, 10 and 14 carbon atoms, respectively. The structures of the benzene, naphthalene and anthracene nuclei are illustrated below, with the carbon atoms available for substitution numbered according to the accepted nomenclature: 




The group R′ may contain substituted or unsubstituted aromatic nuclei RN. Non-limiting examples of the substituents that may be present in the aromatic nucleus RN, include lower alkyl, such as methyl, ethyl, n-propyl, i-propyl, and butyl; aryl; arylalkyl; alkylaryl; halo, such as fluoro, chloro and bromo; acetoxy; alkylacetoxy; arylacetoxy; carboxy; alkylcarboxy; hydroxy; alkoxy; such as methoxy, ethoxy and propoxy; and alkylhydroxy.
The aromatic nucleus RN of the group R′ is connected to the alkoxy spacer  ALK—O. The aromatic nucleus RN may be directly attached to the alkoxy spacer. However, in one preferred embodiment, the group R′ has the structure RN—(CHp)n—, where —(CHp)n— is a group which connects the nucleus RN to the alkoxy spacer. The group —(CHp)n— may be straight-chain or branched, saturated or unsaturated; p is 0, 1, or 2, and n may vary from 1 to 6. In another variant, the group R′ has the structure RN—O—(CHp)q—, where —O—(CHp)q— is the group, which connects the nucleus RN to the alkoxy spacer. The group —O—(CHp)q— may be straight-chain or branched, saturated or unsaturated; p is 0, 1, or 2, and q may vary from 1 to 8.
The group R′ may contain one, two, three or more aromatic nuclei RN. Non-limiting examples of the groups R′ containing a single aromatic nucleus RN are 




Non-limiting examples of the groups R′ containing two aromatic nuclei RN are 




A non-limiting example of the groups R′ containing three aromatic nuclei RN is 




The alkoxy spacer  ALK—O has m number of units of the structure —(R′′′O)m—, which may be same or different, with each R′′′ being an alkyl group, straight-chain or branched, saturated or unsaturated, substituted or unsubstituted, having from 1 to 6 carbon atoms, and m may range from 1 to 300, inclusive. Preferably, the alkoxy spacer  ALK—O includes x number of ethoxy units of the structure  CH2CH2O and y number of propoxy units of the structure 




which may be present in any structural order, such as in blocks, randomly or in alternating pattern. In describing the esters of the invention, the structure of the alkoxy spacer may be shown as, for example, 




Such depiction indicates only the number of ethoxy and propoxy units, and does not indicate the nature of attachment of the alkoxy spacer to the group R′ or the ester group. Further, such depictions of the alkoxy spacer, unless specifically stated, are not intended to indicate the structural order of the ethoxy and propoxy units. For example, the spacer shown as 




does not indicate a block of 4 ethoxy groups attached to a block of 4 propoxy groups. It does mean, however, that the alkoxy spacer having 4 ethoxy and 4 propoxy units is contemplated.

Preferably, the alkoxy spacer  ALK—O contains only epoxy and propoxy units, i.e., m is equal to the sum of x and y; x ranges from 0 to 150, inclusive; y ranges from 0 to 150, inclusive; and the sum of x and y ranges from 1 to 300, inclusive. The organization and quantity of the ethoxy and propoxy groups may have substantial effect on the properties of the ester. Thus, for certain application, such as for use as emollients, esters having the sum of x and y which is less than 20 are preferred. In one group of such esters, x is equal to 0. In another group of such esters, y is equal to 0. In yet another group of such esters, x>0, y>0, and x>y. In yet another group of such esters, x>0, y>0, and y>x. For other applications, such as for use as thickeners, the esters having the sum of x and y greater than 100 are preferred.
The fatty alkyl group R′′ may be straight chain or branched, saturated or unsaturated, substituted or unsubstituted, and may contain from 1 to 39 carbon atoms. More preferably, the fatty alkyl group R′′ does not include an aromatic group. More preferred are aliphatic groups R′′ containing from 1 to 21 carbon atoms. Yet more preferred are the R′′ groups containing 5 to 21 carbon atoms. Most preferably, 7 to 17 carbon atoms are found in the group R′′.
The more preferred esters of alkoxylated aromatic alcohols and fatty carboxylic acids are the compounds of the formulas (I), (II), or (III):

The esters of the invention may be prepared in a variety of ways. The preferred esters of alkoxylated aromatic alcohol and fatty carboxylic acid are products of the reaction: 




where R′, R′′ and  ALK—O are defined above in reference to the product esters, and R* is hydrogen, lower alkyl group, or a carboxylate group. Thus, AAL is an aromatic alkoxylated alcohol and FA is a fatty carboxylic acid, a derivative of a fatty carboxylic acid, such as an ester or an anhydride, or mixtures thereof. Natural oils, synthetic oils and triglycerides that contain fatty carboxylic groups may also be used as the reactant FA.

Non-limiting examples of suitable fatty carboxylic acids include myristic acid, propionic acid, capric acid, lauric acid, behenic acid, erucic acid, linoleic acid, montan acid, phenyl acetic acid, oleic acid, stearic acid, palmitic acid, coconut-oil-derived acid mixture, palm oil-derived acid mixture, and mixtures thereof.
Non-limiting examples of suitable alkoxylated alcohols include alkoxylated benzyl alcohol, alkoxylated phenoxyethanol, alkoxylated cynnamyl alcohol, alkoxylated phenoxy-n-propanol, alkoxylated phenoxy-i-propanol, and mixtures thereof. Other non-limiting examples of suitable alkoxylated alcohols include alkoxylated bisphenol A, alkoxylated bisphenol AF, alkoxylated bisphenol AP, alkoxylated tetramethyl bisphenol A, alkoxylated bisphenol F, alkoxylated bisphenol E, alkoxylated bisphenol C, alkoxylated bisphenol M, alkoxylated bisphenol P, alkoxylated bisphenol S, alkoxylated bisphenol Z and mixtures thereof.
The synthesis of an alkoxylated aromatic alcohol (AAL) typically involves alkoxylation of the corresponding aromatic alcohol. The reaction schemes below illustrate the alkoxylation reaction, showing the ethoxylation/propoxylation of benzyl alcohol: 




and p-di-methylhydroxy benzyl diol: 




Preferably, the alkoxylation is carried out with ethylene oxide, propylene oxide or mixtures of ethylene oxide and propylene oxide. The alkoxylation of mono-hydroxy aromatic alcohols (e.g., benzyl alcohol, cynnamyl alcohol, phenoxyethanol, etc.) provides alkoxylated aromatic alcohols having a single hydroxy group at the end of the alkoxy chain. The alkoxylation of di-hydroxy aromatic alcohols typically provides alkoxylated aromatic alcohols having two hydroxy groups at the end of each alkoxy chain.
The alkoxylation reaction may produce symmetrical or asymmetrical alkoxylated alcohols. The order of the addition of the alkyl oxides (e.g., ethyl oxide and propyl oxide) may be used to vary the nature of the alkoxy substitution in the final esters, including the structural order of ethoxy and propoxy units, and the order of attachment. For example, alkyl oxides may be added sequentially, in a mixture, or in any other desired manner, thus varying the order of the alkoxy substitution. The amounts of alkyl oxide(s) introduced in the reaction zone and the duration of the reaction with the selected alkyl oxide(s) determines the number of moles of the alkyl oxide added to the starting aromatic alcohol. The numbers of ethoxy and propoxy units in the ester effects its properties. Thus, an increase in the amount of ethoxylation may be used to improve the solubility/dispersability of the ester while an increase in the amount of propoxylation improves fluidity.
The alkoxylation reaction may proceed via acidic or basic catalysis in the presence of such catalysts as alkali hydroxides and oxides, protic and Lewis acids, amines, quaternary ammonium compounds, water, and catalysts mixtures. The specific suitable catalysts include, for example, potassium hydroxide, sodium methoxide, sodium borohydride, boron trifluoride, stannic chloride, and sulfuric acid. The preferred catalysts are potassium or sodium hydroxide, sodium methoxide, sodium borohydride or mixtures thereof.
Preferably, the catalyst is used in the amount of from about 0.1 to about 2.0 weight percent of the weight of the desired alkoxylated alcohol. Preferably, the reaction is carried out under anhydrous conditions at from about 110° C. to about 200° C. at pressures of from about 10 psig to about 80 psig. Higher temperatures and pressures may be also utilized. After the reaction is complete, an acid (e.g., phosphoric or acetic acid) may be introduced to neutralize the catalyst.
The alkoxylated aromatic alcohols produced in the alkoxylation reaction are then esterified, providing the esters of alkoxylated aromatic alcohols and fatty carboxylic acid of the invention. The esterification reaction may be carried out in a conventional manner. Typically, the stoichiometric quantities of the alcohol and the fatty acid are combined in the presence of a suitable catalyst. A slight stoichiometric excess of one of the reagents may be employed. The preferred catalysts include methanesulfonic acid and paratoluenesulfonic acid.
Generally, the aromatic alkoxylated alcohol, the acid and the catalyst are combined with mixing to form a reaction mixture. The reaction mixture is heated with mixing at a temperature between about 155° C. and about 250° C., preferably between about 170° C. and 220° C., until an acid value of less than 8 mg KOH, preferably less than 5 mg KOH, is obtained. The reaction mixture is cooled below 85° C. and washed with water. The ester layer is separated and heated under vacuum until moisture content of less than 0.2 percent is obtained.
The esterification of alkoxylated aromatic alcohols having a single hydroxy group is straightforward. If a stoichiometric excess of the fatty acid or the derivative of fatty acid is provided, the alkoxylated aromatic alcohol is entirely consumed in the reaction, providing a monoester of alkoxylated aromatic alcohol and the fatty acid. The reaction scheme below illustrates the esterification of PEG-4, PPG-4 benzyl ether by myristic acid, providing 4-PEG-4-PPG benzyl myristate: 




The esterification of the alkoxylated aromatic alcohols having two or more hydroxy groups capable of being esterified may result in monoesters, diesters and so on. The nature of the esterification product depends on the relative proportions of the fatty carboxylic acid (or the derivative thereof) and the alkoxylated aromatic alcohol. For example, the esterification of alkoxylated aromatic alcohols having two hydroxy groups may result in one or both of the hydroxy groups being esterified, as desired. If a stoichiometric excess of the alkoxylated aromatic alcohol is present in the reaction mixture, the monoester is the predominant product. Conversely, if a stoichiometric excess of the fatty acid is used, the predominant product is the diester.
The reaction scheme below illustrates the esterification of PEG-4, PPG-4 p-di-methylhydroxy benzyl ether by myristic acid, providing either di- or mono-myristate depending on the relative proportions of the reactants: 




The descriptions of the preparation methodologies, including the alkoxylation and esterification reactions, in U.S. Pat. Nos. 5,693,316, 5,597,555, 5,455,025, and 5,302,377 are incorporated herein by reference to the extent such descriptions are relevant to the preparation of the esters of the invention.
The esters of alkoxylated aromatic alcohols and fatty carboxylic acids are useful as ingredients or additives for cosmetic and personal care products. Preferably, the esters described herein are utilized as emollients, solubilizers, diluents, plastisizers, and/or thickeners. As ingredients of personal care and cosmetic products, the esters of alkoxylated aromatic alcohols and fatty carboxylic acids may provide one or more important advantages to the formulator. First of all, the formulations containing the esters of the invention have a non-greasy skin feel desirable for cosmetic and personal care products. This, of course, depends on other ingredients of the formulation.
Further, it has been surprisingly found that the solubility of certain functional ingredients of cosmetic products in certain esters of alkoxylated aromatic alcohols and fatty carboxylic acids is greater than the solubility of the identical active ingredients in the conventionally used emollients. For example, the solubility of benzophenone-3, a known sunscreen active ingredient for sunscreen product formulations, in PPG-3 benzyl myristate is greater than the solubility of benzophenone-3 in the mixture of benzoic acid esters of C12, C13, C14, and C15 linear primary alcohols, which is a known emollient ingredient described in U.S. Pat. No. 4,323,694, which is incorporated herein by reference. The esters of alkoxylated aromatic alcohols and fatty carboxylic acids that dissolve an amount of benzophnone-3 which is 10% or greater than the amount dissolved in the equal quantity of the emollient ingredient described in the '694 patent are preferred.
It is another advantage that the synthetic methodology for preparation of the esters of the invention provides ability to modify the properties of the cosmetic and personal care product containing the esters. For example, by modifying the ratios of ethoxy and propoxy groups in the alkoxy spacer, the fluidity and/or dispersability of the esters in surfactant systems may be varied as the formulator desires. To impart additional fluidity, the propoxy units are included in the alkoxy spacer of the ester. Conversely, the ethoxy units may be included to improve the solubility/dispersability of the esters.
Compounds that impart the products with low spreading properties allow formation of thicker, more uniform films. Such compounds are desirable for obtaining, for example, sunscreen formulations with a high resistance to wash off and a high SPF value. Therefore, the esters of alkoxylated aromatic alcohols and fatty carboxylic acids having a skin spread factor of less than 10 or a viscosity of less then 20,000 cps are preferred. The more preferred esters have a skin spread factor of less than 5 or a viscosity of less then 10,000 cps. The esters that exhibit both low spread factor and viscosity are yet more preferred.
The skin spread factor is determined by applying, for example, 5 microliters of a product to a 3.14 cm diameter circle on the volar surface of the forearm. The product is spread evenly within the circle and allowed to spread for a fifteen minute period. The test site and surrounding area of the forearm is then sprayed with a 1 percent solution of FD&C Blue No. 1. The area not stained by the blue dye indicates the area onto which the product spread. The skin-spread factor is obtained by dividing the resulting area by the initial area. In accordance with the present invention, the test formulations containing the esters of the invention preferably have a skin spread factor of less than about 10, more preferably less than about 5.
Desirable pigment wetting properties may also be obtained by using the esters of the invention. Pigment wetting properties are determined by preparing a dye slurry and measuring viscosity. For example, a slurry can be prepared using an alkoxylated fatty alcohol dicarboxylic acid ester of the present invention mixed with 35 percent mica or any dye. The viscosity of the slurry is determined after allowing the slurry to stand for five minutes. The lower the viscosity, the better the pigment wetting properties of the ester. Preferably, in accordance with the present invention, viscosity of the resulting dye slurry will be below about 20,000 cps, more preferably, less than about 10,000 cps; based on a 65% ester, 35% pigment mixture (measured in weight percent). Viscosity will vary if a different testing mixture is used.
Thus, the invention may provide personal care or cosmetic product compositions that include the esters of alkoxylated aromatic alcohols and fatty carboxylic acids described herein. Such compositions are referred to herein as the final product compositions. The final product compositions of the invention contain from about 0.1% to about 99% of at least one ester of alkoxylated aromatic alcohol and fatty carboxylic acid by weight of the composition. The amount of the ester(s) in the product composition depends on the specific application and formulation design. Preferably, the esters of the invention are present in the amount from about 0.1% to about 40%, more preferably, from about 0.1% to about 10%, yet more preferably, from about 0.5% to about 2% by the weight of the product composition. However, different amounts may be preferred depending on the nature of the product.
In addition to the esters of alkoxylated aromatic alcohols and fatty carboxylic acids, the final product compositions of the invention may include various functional ingredients, including active and additional ingredients, both conventional and otherwise. The decision to include or exclude an ingredient and the selection of specific active and additional ingredients depends on the specific application and product formulation. The line of demarcation between an “active” ingredient and an “additional ingredient” is artificial and dependent on the specific application and product type. A substance that is an “active” ingredient in one application or product may be an “additional” ingredient in another, and vice versa.
Thus, in addition to the esters of alkoxylated aromatic alcohols and fatty carboxylic acids, the final product compositions of the invention may include one or more active ingredients present in the amount from 0.2% to about 60%, preferably, from about 3% to about 40%, more preferably, from about 5% to 25% by weight of the composition. The active ingredients provide some benefit related to the function of the product. Non-limiting examples of the active ingredients include sunscreen compounds, both organic and inorganic, pigments, skin and hair rejuvenating agents, such as bioactives, moisturizers, film formers, hair colors, make-up agents, detergents, thickening agents, emulsifiers, antiseptic agents, deodorant actives and surfactants cleaning agents, hair conditioning agents, skin conditioning agents, hair styling agents, antidandruff agents, hair growth promoters, perfumes, antiseptic agents, surfactants and pharmaceuticals useful for topical purposes for transdermal delivery.

For each type of active ingredient, one or more compounds may be present. Likewise, more than one type of active ingredient may be present in the product composition. The choice of the active ingredient depends on the nature of the desired cosmetic or personal care product. For example, the sunscreens may be used in the sunscreen lotions, shampoos, hair care lotions and the like. The choice of the active ingredient(s) depends on the nature of the desired cosmetic or personal care product. For example, the sunscreen actives may be used in the sunscreen lotions, shampoos, medicated shampoos, hair care lotions and the like.

The clear preparations are preferred. The final product compositions of the invention, including those in the form of products described herein, may be used for both skin and hair. The final product compositions of the invention may also have the form of household cleaning products, household detergent liquids and other similar products.
The final product compositions of the invention may be formulated as aqueous and non-aqueous preparations, including but not limited to topical preparations. In addition to the esters of alkoxylated aromatic alcohols and fatty carboxylic acids, the topical preparations of the invention may contain various active, additional and optional ingredients described in the ingredients section herein.

The particularly preferred final product compositions of the invention are antiperspirant products and sunscreen product formulations. Such more preferred compositions are preferably topically applied to skin or hair. The esters of the invention are highly compatible with silicon liquids, such as cyclomethicone compounds. Cyclomethicones are volatile compounds, which are often included in the antiperspirant products. However, the volatility of the cyclomethicones, which is desired in the antiperspirant products, makes them difficult to handle during formulation processing. It has been surprisingly discovered that certain esters of alkoxylated aromatic alcohols and fatty carboxylic acids reduce the volatility of cyclomethicones in processing without substantially affecting their performance in the antiperspirant products. Thus, the invention also provides antiperspirant product compositions that include the esters of alkoxylated aromatic alcohols and fatty carboxylic acids present in the amount of from about 0.1% to about 40%, more preferably, from about 1% to about 20% by weight of the composition, one or more antiperspirant actives present in the amount of from about 1% to about 20%, more preferably, from about 5% to about 15% by weight of the composition, and one or more cyclomethicone compounds present in the amount of from about 1% to about 40%, more preferably, from about 2% to about 20% by weight of the composition.

A. Preparation Procedure for Test Solutions
To prepare the test solutions, appropriate amounts of Benzophenone-3 was weighed and transferred to a 50-ml beaker equipped with a small stirring bar. The correct amount of the desired ester was added to the beaker and the contents of the beaker were heated on a pre-warmed 70-75° C. hot plate. Once the entire solid has dissolved, the solution was heated for additional 10 minutes. Care was taken to make sure that no solid remained on the sides of the beaker. After 10 minutes, the beaker was removed from the hot plate and placed on a cool stir plate to allow the solution to cool with stirring to approximately 35° C. The solution was transferred to a 2-ounce jar. The contents of the jar remained undisturbed for 24 hours in a 25° C. water bath. After 24 hours, the jars were visually inspected for evidence and degree of crystallization.
B. Test Results
There was no crystal formation for test solutions A and B. Crystal formation was observed for test solutions C and D. The amount of crystals formed in test solution C was approximately three times greater than in test solution D.
