## Title
Functionalized polymeric surfactants based upon alkyl polyglycosides

## Abstract

The invention relates to a series of multifunctional polyglycosides derivatives that are made by the polymerized by the reaction of polyoxyalkylene containing crosslinking reagent and polyglycosides, together with a functionalizing agent that contains a sulfate, sulfonate, quaternary nitrogen, or a phosphate group. The preferred polymers are cross linked having more than one group per molecule. They are made with mild reagents to avoid discoloration and mal odor.

## Background
FIELD OF THE INVENTION
The present invention relates to a series of polyglycoside derivatives that are (a) polymeric (that is cross linked with hydoxypropyl linkages) and (b) contain additional functional groups including alkoxy, sulfate, sulfonate, quaternary and phosphate groups. These polymers have higher molecular weight than the starting materials and as such provide a gloss to the hair and skin and an outstanding softening and conditioning to the skin and hair. The inclusion of the additional functional groups provide increased foam (sulfate and sulfonate), alkali tolerance (phosphate), emulsification (alkoxy), making the products of the present invention highly functionalized, polymeric, products based upon natural raw materials, that are very mild to the eye and skin.
Commercial alkyl polyglycosides generally have a low degree of polymerization of polysaccharide, in the molecule. This results in a molecule that is of limited water solubility. The present invention is aimed at functionalizing the hydrophobic alkyl polyglycoside, by including in the polymeric molecule specific functionalities. These products have been called “alkyl glycosides, alkyl glycosides, alkyl polyglycosides or alkyl polyglycosides” by many different authors. All refer to the same molecules.
BACKGROUND
Alkyl polyglycosides have been known for many years, having been first synthesized in the early 1900 by Emile Fischer. Despite this, the products were of little commercial interest until much later.
U.S. Pat. No. 4,393,203 issued Jul. 12, 1983 to Mao et al, incorporated herein by reference, disclose that long chain fatty alcohols can be removed from alkyl polysaccharide products in thin film evaporators to achieve fatty alcohol levels of less than about 2% without excessive discoloration of the alkyl polysaccharide. This allowed for a more cosmetically acceptable product to be developed that is more surface active. The presence of the free fatty alcohol in the mixture, allows for a more water-soluble product, by removing the water insoluble alcohol.
One of the most significant patents is U.S. Pat. No. 5,003,057 issued Mar. 26, 1991 to McCurry et al incorporated herein by reference, provides for a process for preparing glycosides from a source of saccharide moiety and an alcohol in the presence of a hydrophobic acid catalyst is provided. An example of such a catalyst is dinonylnaphthalenemonosulfonic acid. The use of such catalysts provides a number of process advantages, which includes the reduced production of polar by-products. Preferred glycosides produced by the process are higher alkyl glycosides useful as surfactants.
U.S. Pat. No. 3,598,865 (Lew) discloses the production of higher alkyl (C0.8 -C25) glycosides from a monosaccharide or source thereof and a higher monohydric alcohol in the presence of a latent solvent (lower alcohols) and an acid catalyst selected from the group consisting of sulfuric acid, hydrochloric acid, phosphoric acid, phosphorous acid, toluenesulfonic acid, and boron trifluoride.
U.S. Pat. No. 3,219,656 (Boettner) discloses a process for producing a higher alkyl glycoside by reacting glucose with methanol in the presence of a macroreticular-structured sulfonic acid resin, anhydrous and in the acid form, to produce methyl glycoside which is reacted without isolation with butanol to form butyl glycoside and which in turn is reacted with a higher alcohol to form a surface active higher alkyl glycoside.
U.S. Pat. No. 3,839,319 (Mansfield) discloses a process for producing alkyl glycosides by direct, acid catalyzed reaction of a higher alcohol and a saccharide. The acid catalysts are mineral acids such as hydrochloric and sulfuric, and sulfonic acid exchange resins
The compounds known before the current invention have been primarily used in industrial applications like detergents for dish wash. This is due in part to inherent drying that occurs when these materials are applied to the skin. Many people, one of which is Cognis, have introduced blends of alkyl polyglycosides and traditional surfactants to overcome these limitations. The blending of other alternative surfactants, while demonstrating a long felt need for improvement in the performance of the product, does not address underlying difficulties in the molecule.
None of the patents referenced above provide for a molecule that has the necessary crosslinking or functionalization incorporated into the molecule as to overcome the negatives associated with the use of the raw alkyl glycoside.
THE INVENTION
The present invention relates to the finding that the reaction of the rather hydrophobic alkyl polyglycosides with the proper reagent results in molecules that have improved skin feel, and conditioning attributes thereby overcoming many of the shortcomings of the alkyl polyglycosides itself. It is most interesting that the maximum amount of glycoside units per alkyl group that can be added using known technology is 1.5. This means that the product is a mixture of mono and di functional product. This product has the remaining fatty alcohol stripped off in an evaporative process. The resulting product is about 70% by weight of a product of a d.p. of 1, about 21% by weight of a product of a d.p. of 2, about 7% by weight of a product having a d.p. of 3, and about 2% by weight of a product that has a d.p. of 4.
We have surprisingly learned that taking the alkyl polyglycosides produced in the commercial process, with its inherent lack of water solubility and reacting it to make cross linked polymers, and include functional groups, including alkoxy, sulfate, sulfonate, quaternary and phosphate groups results in a series of products that are much more usable in many applications.
SUMMARY OF THE INVENTION
Alkyl polyglycosides are complex products made by the reaction of glucose and fatty alcohol. In dealing with the chemistry one talks about degree of polymerization (the so called “d.p.”). In the case of traditional alkyl polyglycosides the d.p. is around 1.4. This means that on average thee is 1.4 units of glucose for each alkyl group. The fact of the matter is that the resulting material is a mixture having an average of 1.4.
The specific structure of the product is hard to ascertain completely since many positional isomers are possible, but two examples of structures are as follows;




It should be clear that if there is a 50/50 mixture of the d.p. 1 and d.p. 2 product, the resulting analytical data will show that on average there is a d.p. of 1.5. Saying that a molecule has a d.p. of 1.5 does not mean that each molecule has 1.5 glucose units on it.
One key aspects of the present invention relates to the heretofore unappreciated fact that the rather hydrophobic alkyl polyglycosides contain on average five hydroxyl groups, one primary and the other four secondary. The assumption that there is a large degree of group specificity for the primary to react exclusively rather than the four additional hydroxyl groups is simply not true. This means that if on average only one of the five groups is reacted, there remains a very large concentration of reacting alkyl polyglycoside that has no functionality on it. Since the reactant with no functionalization remains water insoluble, there needs to be at lease 2 and as many as 4 hydroxyl groups functionalized to get to the desired water-soluble product. We have observed that when between 2 and 5 groups are reacted, a water-soluble very useful product results. Therefore it is a preferred embodiment having between 2 and 5 of the hydroxyl groups functionalized.
Another key unappreciated fact in making the compounds of the present invention is the selection of the proper reagents to make the desired product. Specifically, the reaction of the alkyl polyglycoside with a certain family of epoxy compounds and related materials occurs under mild aqueous conditions and results in a mild cationic conditioner useful in hair and skin care products.


DETAILED DESCRIPTION OF THE INVENTION
The compositions of the present invention are prepared by reacting the mixtures conform to the following structures:




wherein;

    
    
        R is alkyl having 8 to 22 carbon atoms; and
    
    






wherein;

    
    
        R is alkyl having 8 to 22 carbon atoms;

with a polymerizing agent conforming to the following structure

Cl—CH2CH(OH)CH2O—(CH2CH2O)a—(CH2CH(CH3)O)bCH2CH(OH)CH2Cl

        a is an integer ranging from 1 to 20;
        b is an integer ranging from 1 to 20;

and

optionally a functionalizing agent selected from the group consisting of:

    
    






Cl—CH2—CH(OH)—SO3 M;

Cl—CH2—CH(OH)CH2—SO4 M;

Cl—CH2—CH(OH)—CH2—OP(O)—(O M)2;

and mixtures thereof,

wherein:

    
    
        R1 is CH3—(CH2)n—
        n is an integer ranging from 6 to 36;
        M is needed for charge balance and is selected from the group consisting of

H, Na, K, or NH4.

    
    


It will become clear that the compositions of the present invention need to be claimed as product by process, since they are the reaction product of a multi-hydroxyl product and a di-chloro intermediate. Since there is not a great deal of group specificity in the reaction of the various hydroxyl groups, cross linked polymers result. The degree of cross linking depends upon the ratio of 1,3 dichloro isopropanol to hydroxyl groups chosen. The functionalizing agent likewise reacts with hydroxyl groups, providing a multifunctional polymer.
By considering the reaction in steps, it will make the reaction pathway clearer.




    
    
        R′′ is

—CH2CH(OH)CH2O—(CH2CH2O)a—(CH2CH(CH3)O)bCH2CH(OH)CH2—

        a is an integer ranging from 1 to 20;
        b is an integer ranging from 1 to 20;
    
    


The polymerization agent reacts with the first hydroxyl group giving an intermediate:




The above reaction shows one of the possible reacted hydroxyl groups. There is a potential for reaction of the other hydroxyl groups as well. Subsequently, another hydroxyl group reacts to give:




FUNCTIONALIZATION
The optional functionalization group is added to one of the additional hydroxyl groups for example:




wherein

    
    
        R2 is —CH2—CH(OH)—CH2—SO3 Na.
    
    


As the reaction continues more and more hydroxyl groups react with either the polymerizing agent or the functionalizing agent. The structure is complicated not only by the fact that many hydroxyl groups can react with the different types of agent, but also by the fact that commercial polyglycosides are mixtures having an average dp of 1.5. The resulting products are hydroxypropyl cross linked polymers having branching present. This is the reason for claiming the products in a product by process format.
Another aspect of the present invention is a process for conditioning hair and skin which comprises contacting the hair and skin with an effective conditioning concentration of a composition prepared by reacting a composition conforming to the following:

EXAMPLES
Preparation of Alkyl Glycosides
Alkyl Glycosides are raw materials used to make the surface-active polyglycoside derivatives of the present invention.
Saccharides useful in the process of making alkyl glycosides are saccharides that can be alkylated in the “1” position, commonly referred to as “reducing saccharides”, or higher saccharides that can be hydrolyzed to provide such a saccharide. These saccharides are typically comprised of aldo- or keto-hexoses or pentoses.
Examples of saccharides include glucose (dextrose), fructose, mannose, galactose, talose, allose, altrose, idose, arabinose, xylose, lyxose, and ribose. Examples of hydrolyzable saccharides that are a source of reducing saccharides include starch, maltose, sucrose, lactose, maltotriose, xylobiose, mellibiose, cellobiose, raffinose, stachiose, methyl glycosides, butyl glycosides, levoglucosan, and 1,6-anhydroglucofuranose.
The physical form of the saccharide may vary. The saccharide will typically be in a fluid (as opposed to a solid) state, e.g. as a melt or an aqueous syrup, during at least a portion of the period of reaction, if not for a predominant portion of the period of the reaction. Crystalline (e.g. anhydrous or hydrates) or amorphous saccharide solids in various particle sizes, e.g. granules, powders, etc., can be used, but the heating of the reaction medium may well fluidize at least a portion of a solid reactant, if not a predominant portion of the saccharide reactant. Aqueous syrups of saccharides, typically at saccharide solids of between about 10% and 90% dry solids by weight can also be used. Indeed, the use of the hydrophobic catalysts of this invention should show the most improved results over conventional catalysts in the context of the use of aqueous syrup reactants as compared with processes which employ solid saccharide reactants, particularly with respect to avoiding the formation of deleterious amounts of polysaccharides and very high DP alkyl glycosides during the glycoside formation reaction.
The preferred saccharides are glucose, galactose, xylose and arabinose, or mixtures thereof, for reasons of availability, low cost, and convenience. Glucose in the anhydrous crystalline form is preferred, although dextrose monohydrate, corn syrups of high dry solids (typically 50% to 80% dry solids) and a high dextrose equivalence (D.E.) (typically greater than 90 D.E and most commonly 95 D.E.) can be commonly employed. Indeed, while the higher the purity of the dextrose source, the better the quality of the product (other things being equal), the catalysts of this invention allow the use of a lower purity dextrose source and yet yield a product of substantially equivalent quality as compared with prior catalysts. Because of the ready availability of glucose and its oligomers, much of the remaining description is particularly suited to the use of glucose in its various forms.
Alcohols useful in the process of this invention are hydroxyl-functional organic compounds capable of alkylating a saccharide in the “1” position. The alcohol can be naturally occurring, synthetic, or derived from natural sources and/or derivatized. Examples include monohydric alcohols (more fully discussed below) and polyhydric alcohols (e.g. ethylene glycol, propylene glycol, polyethylene glycols, polypropylene glycols, butylene glycol, glycerol, trimethylolpropane, pentaerythritol polyester polyols, polyisocyanate polyols, and so on). Other examples include aromatic alcohols such as benzyl alcohol, phenol, substituted phenols (e.g. alkylphenols) and alkoxylates of each.
Preferred alcohols are monohydric alcohols containing from about 1 to about 30 carbon atoms. They may be primary or secondary alcohols, straight or branched chain, saturated or unsaturated (e.g. allyl alcohol, 2-ethylhexenyl alcohol and oleyl alcohol) alkyl or aralkyl alcohols, ether alcohols, cyclic alcohols, or heterocyclic alcohols. In general, these alcohols have minimal solvent power for the saccharide molecule. Examples of the monohydric alcohols which may be employed in the present invention include methyl alcohol, isopropyl alcohol, butyl alcohol, octyl alcohol, nonyl alcohol, decyl alcohol, dodecyl alcohol, tridecyl alcohol, tetradecyl alcohol, pentadecyl alcohol, hexadecyl alcohol, pentacosyl alcohol, oleyl alcohol, linoleyl alcohol, isoborneol alcohol, hydroabietyl alcohol, phenoxyethanol, phenoxypolyethoxyethanol containing five ethoxy groups, 2-methyl-7-ethyl-4-undecanol, and mixtures of one or more of the above.
A preferred group of alcohols are alkanols having the formula ROH wherein R represents an alkyl group having from 8 to 30 carbon atoms. A particularly preferred group of alcohols are those wherein R represents an alkyl radical having from 8 to 20, preferably 11 to 18, carbon atoms. The alkyls can be straight or branched chain.
ALKYL GLYCOSIDE EXAMPLES
Example 1
A one-liter, four-necked, round-bottomed flask was equipped through its center neck with an overhead mechanical stirrer, through a second neck with a distillation head fitted with an addition funnel and a condenser/receiver/vacuum take-off assembly, through a third neck fitted with a three hole rubber stopper with a capillary nitrogen bleed, a calibrated mercury thermometer and a vacuum tight temperature controller probe, and on the fourth neck with a septum for sampling.
The flask was charged with 602.4 g (3.105 moles) of a commercial mixture of C11 to C15 (98% C12 and C13) straight and branched alkanols (Neodol 23 available form Shell Chemical Co.) and 136.6 g (0.69 moles) of a commercially available dextrose monohydrate (Staleydex 333, available from A. E. Staley Mfg. Co. at 9.0% moisture). The slurry was heated at a vacuum of 30 mm Hg (absolute). Water was released starting at about 57.degree. C. and heating was continued until the slurry had reached 110.degree. C. At this time 3.2 g (0.00345 mole of a commercially available mixture of 50% dinonylnaphthalenesulfonic acid in heptane (available from King Industries) was added as a catalyst and the theoretical volume of water distilled at about a linear rate over 8 hours. After stirring an additional hour, a stoichiometric amount of aqueous NaOH (33% in H2O) was added. An aliquot of the neutralized reaction mixture (3.39 g, 1 g dissolved substance) was dissolved in a total volume of 10 ml with 1:1 isopropanol:water. The pH of this solution was 7.8.
The remainder of the reaction mixture was evaporated to a clear melt at 200.degree. C. and 1 mm pressure using a Leybold-Heraeus Distact.TM wiped film evaporator operating at a feed rate of 700 ml/hr.
The residue was analyzed using a combination of gas and liquid chromatographic techniques as well as NMR spectroscopy and was shown to contain less than 0.2% free alcohol and less than 2% polar species (HPLC) and an NMR mole ratio of glucose rings to fatty chains of about 1.4.

ALKYL POLYGLYCOSIDES FUNCTIONAIZED PRODUCTS
There are a number of water-soluble groups that can be introduced into the finished alkyl polyglycoside. These include phosphates; sulfates, alkoxylate and quaternary groups.
It will be clearly understood that the alkyl polyglycosides of the present invention have a number of hydroxyl groups present in the molecule. The number of hydroxyl groups functionalized will have a profound effect upon the degree of increased water solubility of the molecule.
The present invention includes a functionalization of a low number of hydroxyl groups (one per molecule) to a high number (all groups on the molecule). The preferred number to functionalize is an intermediate number of groups (approximately half of the number present).

General Procedure—To a flask equipped with agitation, heat, thermometer and nitrogen sparge is added the specified amount of the specified alkyl polyglycoside (example 1-9) and enough water to make the final product have a solids of 35% by weight. The alkyl polyglycoside is heated to melt. Next, the specified amount of crosslinking reagent is ( Example 10a-10c) added under good agitation and nitrogen sparge. Next is added 0.5 % sodium methylate. Next add the specified number of grams of the specified functionalizing agent (Examples 11-19). The % is by weight and is based upon the total amount of all materials reacted. Nitrogen sparge is simply nitrogen bubbled through the liquid contents of the flask. This keeps the color light, minimizing oxidation and color formation. The reaction mass is heated to 90-100° C., and is held for 5-8 hours. The reaction progress is monitored by formation of chloride ion. Once the theoretical value is reached, the reaction is terminated and the product is used without additional purification.
It will be clearly understood that the alkyl polyglycoside has on average five hydroxyl groups when the d.p. is 1.4. The phosphation can include all five, but in a more preferred embodiment includes between one and three hydroxyl groups. This ratio provides the best degree of water solubility.

The compounds of the invention range from clear yellow liquids to pastes. The compounds are compatible with anionic surfactants like lauryl ether sulfates and are highly conditioning to the hair, providing soft smooth hair. The presence of the blocks of polyoxyalkylene groups provides improved detergency, foam and mildness.
The ability to formulate clear products with anionic surfactants makes these compounds of particular importance for use in personal care applications like bubble bath, shampoos and body wash. They are also very good additives for hard surface cleaners and detergent systems.
The products of the current invention differ significantly from the alkyl polyglycosides that have not been polymerized in several key respects. The polymerized materials are less sticky, glossier and provide much improved softening and conditioning properties to the skin.
While the illustrative embodiments of the invention have been described with particularity, it will be understood that various other modifications will be apparent to and can be readily made by those skilled in the art without departing from the spirit and scope of the invention. Accordingly, it is not intended that the scope of the claims appended hereto be limited to the examples and descriptions set forth hereinabove but rather that the claims be construed as encompassing all the features of patentable novelty which reside in the present invention, including all features which would be treated as equivalents thereof by those skilled in the art to which the invention pertains.
