Description

RELATED PATENT APPLICATIONS

[001] The present patent application claims the benefit of priority to U.S. Provisional Patent Application no. 62/588,491, filed on November 20, 2017, the full content of which is incorporated into this document by way of reference.

BACKGROUND

[002] Hair combing or styling compositions are widely used to maintain a particular shape or style of hair. Unfortunately, even after expensive and long hairdressing sessions, there are very few products that provide adequate protection against hair loss, particularly in ambient conditions such as high humidity. As every consumer in the cosmetics industry with wavy or curly hair will know, humidity and dampness are fatal to even the most elaborate hairstyles.

[003] A common solution to this problem is the use of styling gels, hair foams, hair waxes, hair sprays, fixing gels, and others. These types of products, however, are often not effective, and most of them tend to leave hair feeling sticky and unnatural. Therefore, there is currently a need for a truly effective product that allows hairstyles to withstand adverse environmental conditions and leaves hair feeling soft and natural (i.e., with good sensory attributes).

SUMMARY

[004] Previously, it was identified that water-conducted polyurethanes that possess certain properties could produce cosmetic compositions with enhanced maintenance, wave retention with high humidity, and/or positive sensory attributes. See patent document WO 20171155906, the content of which is incorporated herein by reference. Here, it has now been found that these properties extend to other chemistries, each of which has similar affirmative results, thereby increasing the quantity and versatility of hairstyling products available to the consumer.

[005] Therefore, herein provided are hairstyling compositions comprising one or more polymers that are not based on polyurethane or urea polyurethane that have a Young's modulus above 150 MPa; an elongation at break of about 15% to about 300%; and a moisture absorption of less than 10%.

[006] It was found that the compositions described in this document provide outstanding results in vivo. See, for example, FIGURE 3 which shows a direct comparison between an acrylate copolymer composition having the disclosed Young's modulus, elongation at break, and moisture absorption and an acrylate copolymer composition that falls outside the scope of of these properties. As shown by the results, excellent waveform retention and definition was obtained with the compositions of the invention even under conditions of high humidity.

DETAILED DESCRIPTION 1. Definitions

[0010] A "styling" product or a "styling" composition is one that can be used to change the texture and/or shape of hair, or to maintain hair in a particular style, e.g., a curl, a wave, a feather, a long curl, etc. Types of hairstyling products include, but are not limited to, gels, waxes, mousses, pomades, hair sprays, hair conditioners, and others.

[0011] As used herein, a "non-polyurethane polymer" means a polymer that does not comprise organic units joined by an -O-C(O)-NH- unit.

[0012] As used herein, a "non-polyurethane urea-based polymer" means a polymer that does not comprise organic units joined by an -O-C(O)-NH- bond and an -NH-C(O) bond -NH-.

[0013] The "Young's modulus (or modulus of elasticity, modulus of tension)" is a measure of the stiffness of a solid polymer film. Young's modulus, E, can be calculated by dividing the tensile strength by the extensional stress in the elastic (initial, linear) portion of the stress-stress curve. The Young's modulus of the disclosed polymers can be determined by a defined protocol for measuring mechanical properties, and is developed in reference to the testing guidelines of ASTM D638 and ASTM D412, as described below in Example 2.

[0014] The "elongation at break (also known as the fracture request, ultimate elongation)" is the ratio of the changed length to the initial length after rupture of a solid polymer film. The elongation at break of the disclosed polymers can be determined by a defined protocol for measuring mechanical properties, and is developed in reference to the testing guidelines of ASTM D638 and ASTM D412, as described below in Example 2.

[0015] "Moisture absorption" is the measure of water adsorbed by a solid polymer film. The method for determining the moisture absorption of the disclosed polymers is provided in Example 3.

[0016] The "sensory rating" is determined by the hair holding performance. In particular, the braid with the applied composition is blown dry for 90 seconds. Bunches are prepared in duplicate and blind at random and evaluated for natural feel and total sensory attributes in a range of -2 to 2 by trained sensory analysts under blind conditions. Sensory analysts are licensed hairdressers and cosmetic scientists with significant long-term experience who evaluate the sensory attributes of hair. Sensory analysts assign a -2 rating to curls judged as completely undesirable, a +2 rating to the completely natural soft feel and appearance of the hair, and intermediate ratings between these two extremes.

EXEMPLIFICATION Example 1. Chemical Compositions and Properties

[0055] The compositions were formulated using water or a mixture of water and ethanol. The ratio between the constituents in the final mixture along with the properties is shown in Table 1. Table 1

[0056] Table 2 below shows processing information related to the compositional breakdown of materials. Table 2

Example 2. Mechanical Performance

[0057] Young's modulus is a measure of a material's ability to withstand changes in length when under uniaxial tension or compression. A higher Young's modulus typically indicates that the material is stiffer. The elongation at break, also known as the stress at fracture, is the ratio between the changed length and the initial length after rupture of the specimen. A higher elongation at break expresses a material's ability to resist fracture. For a composition applied to hair to maintain hair shape, the Young's modulus and elongation at break of the composition must be such that the composition imparts rigidity to the hair but does not become brittle.

[0058] A comparison of Young's modulus and elongation at break for some of the polyurethanes disclosed herein was made for several commercially available polyurethane products. Young's modulus and elongation at break can be determined by a defined protocol for measuring mechanical properties that is developed in accordance with the testing guidelines of ASTM D638 and ASTM D412. In particular, the following protocol can be used to determine the Young's modulus and elongation at break (or ultimate elongation) of dry polyurethane film. The test requires approximately 10 to 20 minutes per sample to complete.

[0059] Materials: >25 g of aqueous dispersion of the polymer 1 clean rectangular mold (2 mm x 20 mm x 45 mm) grooved on a Teflon sheet per sample 1 clean razor blade Scotch adhesive tape Universal Testing Machine assembled with geometry extension retention

[0060] Sample Preparation: 1. Prepare 25 g of 10% by weight polymer solution from its respective starting solution. 2. Apply 2.5 ml of the prepared solution to each mold (2 mm x 20 mm x 45 mm) and let it dry for 2 days to obtain the polymer film. 3. After drying, use a spatula to remove the film from the mold. 4. Use the razor blade to cut the corners and obtain a film approximately 15 mm wide and approximately 150 to 300 microns thick. Make sure the film is free of air bubbles. 5. Label the test film. 6. Cut four pieces of adhesive tape (20 mm) per sample and adhere them to both sides of the specimen strip and shape a sample into the shape of a dog bone to improve sample retention in the clamp. Store the prepared test films in desiccators for 1 to 2 hours to dry them completely. Take a sample from the desiccators at one time for testing.

[0061] Sample Testing 1. Balance the load register on the universal testing machine so that the reading is 0 newtons. 2. Use a gauge to adjust a distance of 20 mm between the top and bottom extension retaining geometries. 3. Mount a sample onto the extension retainers and secure it firmly, ensuring that the scotch tape is not visible, and that the sample is as close to vertical as possible in both vertical planes. 4. Stretch the sample slightly, separating the geometries until a force of 2 to 5 N is registered. 5. Start a tension test run on the universal testing machine at a speed of 100 mm/min, stopping the test when the sample fractures. 6. The elongation at break is calculated to the elongation at which the material fractures. 7. Young's modulus is calculated as the modulus during the initial elastic part of the deformation when calculating the slope of a linear fit for that region with a value of R > 0.99. a) low modulus and high elongation, which leads to inferior wave retention (e.g., retention is temporary, transient, or short-lived) or b) high modulus and low elongation, which leads to a brittle material with poor performance ( for example, the resin is brittle or fractures after handling.

Example 3. Hydrophobic/Water Absorption Capacity of Polyurethane

[0062] The following protocol can be used to determine the moisture absorption capacity of disclosed polymers under a high humidity environment. The test requires approximately 2 to 3 days per sample set to complete.

[0063] Materials > 15 g of polymer solution 1. Clean cell culture Petri dish (60 mm diameter x 15 mm height) per sample Humidity chamber with flexibility to control temperature and relative humidity (RH)

[0064] Sample Test 2. Prepare 15 g of 10% by weight polymer solution from the respective starting solution. 3. Label the cell culture Petri dishes for each sample and measure their empty weight (Wpd). 4. Apply 4 ml of the prepared solution to each Petri dish (3 samples per polymer and let it equilibrate for 20 hours at 25°C and 50% RH in the humidity chamber. 5. After equilibration, measure and record the weight of the sample (Wi). 6. Place the samples in the humidity chamber at 25°C and 90% RH and leave to equilibrate to high humidity for 20 hours. 7. Measure and record the final sample weight (Wf) .

[0065] Sample Analysis Calculate the % moisture absorption using the following equation:

Example 4. Braid Test

[0066] Systematic in vitro performance testing on the disclosed compositions and those without the target mechanical properties and water absorption (Table 3) were tested. Throughout the in vitro test, materials were applied at a solids concentration of 3% by weight. The results show that materials with the target properties result in excellent wave retention at high humidity compared to materials without the ideal properties. Table 3

[0067] As shown by FIGURE 1, compositions of the invention having Young's modulus, elongation at break, and water absorption disclosed, exhibited excellent wave retention at high humidity - the waves remained intact and did not fell drastically. On the other hand, the waves where materials with sub-optimal properties were applied fell drastically after equilibration at a relative humidity of 90%. A summary of the in vitro tests performed is provided in Table 4. Table 4

Example 5. In vivo performance

[0068] To validate the in vitro results, and evaluate the performance under normal conditions of use of the hair care product, systematic in vivo performance tests were carried out on compositions of the invention and non-inventive compositions (i.e., those that do not have Young's modulus, elongation at break and water absorption disclosed). In in vivo tests, the materials were applied at a concentration of 3% by weight of solids. The results showed that materials with target properties have excellent hairstyle maintenance, unlike materials without the combination of ideal properties, which do not perform as well. FIGURE 2 shows an example of a hairstyle in which the left side of the head was treated with the acrylate copolymer that does not have the disclosed Young's modulus, elongation at break and water absorption, and the right side of the head was treated with the acrylate copolymer that has the target properties. The material that has the disclosed Young's modulus, elongation at break and water absorption (right) gives more volume and a consistent rounded style to the hair after a blow of air, which is very desirable. Material that is not outside the scope of these properties gives a limp hairstyle with less volume. FIGURE 2 also shows that the composition of the invention (right) results in more aligned hair with minimal loose fibers, and is therefore more desirable than combed hair when using the material without the described combination of properties (left). .

[0069] FIGURE 3 shows an example of the wave retention test after exposure to high humidity. The left side of the head was treated with the acrylate copolymer outside the target zone and the right side of the head was treated with the acrylate copolymer that has published Young's modulus, elongation at break and water absorption values. The composition of the invention (right) showed better maintenance of the initial style and significantly better wave retention after exposure to high humidity. The composition that falls outside the scope of the target properties (left) resulted in a drastic drop in wavelength after exposure to high humidity.

[0070] These results support the discovery that styling compositions comprising one or more polymers that are not based on polyurethane or urea polyurethane have a Young's modulus above 150 MPa; an elongation at break of about 15% to about 300%; and moisture absorption of less than 10%, produces superior styling maintenance and retains the wavy shape under harsh environmental conditions such as, for example, high humidity.

Example 5. Sensory Performance

[0071] The sensory properties of hair treated with various materials were evaluated by blindly trained sensory evaluators for properties such as fiber alignment, hair softness and overall appearance in a range of -2 to +2.

[0072] The material that does not have the disclosed properties (acrylates copolymer) was modified with four different materials (acrylates/octylacrylamide copolymer, modified corn starch, acrylates copolymer, or octylacrylamides/acrylates copolymer /butyl amino ethyl methacrylate), resulting in four compositions of the invention that have the disclosed Young's modulus, elongation at break and water absorption. When hair treated with these materials was classified by sensory evaluators, in 75% of cases materials that have ideal properties had better sensory properties compared to materials that do not have ideal properties (Table 5). Furthermore, when a material outside the target property zone that has a good sensory score (such as acrylate copolymer or modified corn starch) is optimized to meet the target properties, its sensory ratings are not significantly impacted. . Table 5 a"Counts are assigned by blindly trained sensory assessors, in a range of -2 to +2.
