## Abstract

The present invention is directed to water-resistant compositions comprising: a reaction product of at least one lactone compound and at least one amine compound chosen from amino alcohol compounds and alkoxylated amine compounds; and optionally, at least one carrier. These water-resistant compositions are capable of providing or acting as a carrier for delivering benefits to various substrates, for example, keratinous substrates such as skin and hair, while at the same time, imparting durable or long lasting hydrophobicity and/or a protective barrier onto said substrates.

## Background
FIELD OF THE INVENTION
The present invention relates to water resistant compositions and methods of using these compositions on various substrates. More particularly, the invention is directed to a composition containing the reaction product of at least one lactone compound and at least one amine compound chosen from amino alcohol compounds and alkoxylated amine compounds.
BACKGROUND OF THE INVENTION
Consumer products such as cosmetics, personal care and household products are designed to provide a wide range of desirable properties and benefits to various substrates such as keratinous substrates, hard surfaces, and other non-keratinous substrates, for example, fabrics and personal articles. Generally, these products deliver benefit agents to a substrate. These products can also be designed to protect said substrates from extreme environmental conditions or from physical contact such as rubbing or from exposure to water, humidity, moisture or other liquids.
In particular, when keratinous substrates such as skin and hair are exposed to environmental conditions, for example, high or low humidity or to ultraviolet radiation from the sun, these substrates can lose many of their desirable properties and even become damaged. The appearance and condition of skin and hair can also be affected by ultraviolet exposure and aging. For example, skin can become dry and flaky, while hair can dry out and lose its shine or color or become frizzy and less manageable under low and high humidity conditions. Under low humidity conditions, hair can dry out and dried-out hair tends to be less shiny and more brittle. Conversely, under high humidity conditions, hair tends to absorb water causing hair to lose its shape and become unmanageable and unattractive. Furthermore, hair can lose its desirable attributes due to physical stress on the hair such as brushing and application of heat.
As a result, consumers continue to seek products such as sunscreens, skin care, hair care and hair cosmetic compositions which protect and enhance the appearance of skin and hair as well as reduce the deleterious effects of adverse environmental conditions, photo-damage, and physical stress. It is thus important to ensure that the beneficial properties of such products remain on the skin and hair by making these products water resistant and/or able to provide a protective barrier or hydrophobicity to the skin and hair as well as durable or long-lasting hydrophobicity.
Water resistant products do not easily “run off” or wash off when the skin and hair are exposed to water, rain, and tears or upon sweating nor easily transfer from the skin or hair because of normal every day activity. These products also tend to have long wearing and transfer-resistant properties, that is, they adhere longer to surfaces and to keratinous substrates. Commercial products which have these properties may require high amounts of paraffin, fatty alcohols, petrolatum, Vaseline, waxes or oils, e.g., mineral oil. Other customary barrier agents are silicones and conventional film forming agents or polymers. However, such ingredients still present many disadvantages; for example, high levels of oils and hydrocarbon-based ingredients make the skin or hair greasy, waxes can give an unpleasant aesthetic look and feel, and silicones can leave residues and may give an uncomfortable feel and wear.
Thus, there still exists a need to find other materials or compositions that can provide a water-resistant and/or protective barrier to the skin and hair and which do not require the customary barrier agents.
Thus, it is an object of the present invention to provide materials and compositions which provide a water resistant protective barrier onto skin and hair, as well as impart durable or long lasting hydrophobicity and improve the water resistance of cosmetic and personal care compositions. It is also an object of the present invention to provide a water resistant composition that can function as a carrier and/or matrix for desired benefit agents used to benefit skin and hair.

EXAMPLES
Water Resistance Evaluation
Water resistance of compositions for application onto skin was evaluated according to an in vitro water resistance test for skin (“WR Test I”) that is based on a measurement of the quantity one or more organic sunscreens recovered from a substrate initially treated with a composition containing the organic sunscreen(s) after water immersion. The substrate consists of polymethylmethacrylate (PMMA)-coated plates (“PMMA plates”) from Europlast, Inc. and were found to be suitable substitute substrates for skin (see Ahn, S., Yang, N., Lee, H. Alternative Evaluation Method In Vitro for the Water Resistant Effect of Sunscreen Products, J. of Skin Research and Technology. Jul. 22, 2007.) The in vitro water resistance test for skin according to the present invention was employed as an alternative to in vivo testing on skin. The test is as follows:
A measured amount (18-20 mg) of a test composition (test sample) containing the organic sunscreen was distributed onto the surfaces of 8 PMMA plates to form treated plates and allowed to dry for 30 to 40 minutes in the dark. Two of the treated plates were designated as the control plates. The rest of the treated plates were designated as the test plates. The test plates were then attached to holders and immersed in a water bath for a specified period of time, such as 30 minutes, wherein the water was stirred at constant speed by a propeller device and the temperature of the water was at 23 degrees centigrade. The plates were then allowed to dry for 30 minutes. The composition remaining on the plates was twice extracted by 35 ml of alcohol (in this case, methanol) from the plate. The combined alcohol extract was diluted to 100 ml with alcohol to form a sample extract solution (“sample extract”) from which a 9 ml aliquot was taken and diluted to 25 ml. The absorbance of the final extract solution for each sample was obtained by measuring the ultraviolet (UV) absorbance maximum.
The control plates were not subjected to the water immersion step described above. However, the same alcohol extraction procedure as above was performed on the control plates and the UV absorbance maximum for the control sample extract solution (“control extract”) was measured.
The percent water-resistance (% WR) of the test composition is determined as:

% WR(WR Test I)=RA(sample extract)/RA(control extract)×100 wherein RA is the relative absorbance such that:

RA(sample extract)=Absorbance(sample extract)/Weight of test composition; and

RA(control extract)=Absorbance(control extract)/Weight of test composition*

*weight of test composition on control plates.

When comparing % WR among several compositions, a higher % WR means that a higher amount of the composition remained on the plate, indicating that the composition is more water resistant.

The results from the water resistance test above show that the degree of water resistance by the inventive composition, Cream D, is higher and therefore, significantly better than that of the other creams that did not contain both meadowfoam delta-lactone and AMP since the higher the % WR, the more water-resistant the composition is. This result also demonstrates that the composition containing the reaction product provided water resistance and long lasting and durable hydrophobicity onto a surface, which would extend the beneficial effects provided by the sunscreens or any active ingredient in the cream composition when such a composition is applied onto keratinous substrates such as skin or hair.
Water Resistance Study on Hair
Water resistance of compositions for application onto hair was evaluated according to an in vitro water resistance test for hair (“WR Test II”). Various types of hair, including permed, bleached, relaxed or virgin hair may be used. The WR Test II is based on a measurement of the quantity a water soluble organic sunscreen (designated as a “marker”) that is released/dissolves into water after immersing the hair in water, wherein the hair was initially treated with a composition containing the marker sunscreen. The concentration of organic sunscreen that is released into the water is directly proportional to the degree of water resistance or hydrophobicity imparted to the hair by the composition.
The treatment of the hair samples may performed in one of two ways: (A) directly treated with a test/control composition containing the marker sunscreen (“WR Test IIA”); or (B) first treated with an aqueous solution containing the marker sunscreen, then treated with the test/control composition (“WR Test IIB”). The hair samples may be treated by spraying, massaging, spreading or combing the test/control composition onto the hair or by dipping the hair into said composition. The treated hair samples for both control and test compositions are dried and placed in small perforated baskets. The baskets are then immersed in water and rotated at a constant speed for a period of time (e.g., 180 minutes) at 23 degrees centigrade. The concentrations of benzophenone-4 that is removed or released from the treated hair samples are obtained by measuring the UV absorbance maxima of the water based on a calibration curve.
The percent water-resistance (WR) of the test composition is determined as:

% WR(WR Test IIA or IIB)=100−[RA(Test)/RA(Control)×100] wherein RA is the relative absorbance such that

RA(test)=Absorbance(Test)/Weight of treated hair before water immersion; and

RA(control)=Absorbance(Control)/Weight of the treated hair before water immersion.

Example 2
Water Resistance Study on Hair following the WR Test IIB
Bleached hair samples were soaked in a 1% by weight of benzophenone-4 in water solution for 30 minutes and allowed to dry overnight at room temperature. Ethanol-based control and test compositions as tabulated below were then applied onto the hair samples for 30 minutes and the resulting treated hair samples were allowed to air dry. Following the WR Test IIB described above, the treated hair samples were immersed in water for 180 minutes and the benzophenone-4 concentration in the water and % WR were measured.
The results are:

The calculated % WR values for compositions 5, 6, 7, 8 and 9 were 16.77%, 21.66%, 23.82%, 15.3% and 19.80%, respectively.
The results above show that compositions 5 to 9, containing the reaction products, were significantly more water resistant as evidenced by the lower amount of benzophenone-4 that was present in the water compared to amounts of benzophenone-4 corresponding to the other compositions which did not contain the reaction product. This demonstrates that the compositions containing the reaction products provided water resistance properties and long lasting and durable hydrophobicity onto the hair; at the same time, they inhibited the water from passing through the hair and washing the composition off the hair.
