Disclosed are hair styling compositions comprising at least two latex polymers chosen from acrylate and polyurethane polymers, wherein at least one latex polymer is a film-forming polymer, and at least one component chosen from coalescing agents and plasticizers. Methods of styling the hair are also disclosed.
The disclosure relates to hair styling compositions comprising at least two latex polymers, wherein at least one latex polymer is a film-forming polymer, and at least one component chosen from coalescing agents and plasticizers. In various embodiments of the disclosure, the at least two latex polymers are chosen to have certain properties. Compositions comprising the at least two latex polymers and at least one component chosen from coalescing agents and plasticizers may, according to certain embodiments, form films that have surprising properties. Methods of styling the hair with such compositions are also disclosed.
Other known cosmetic compositions include various components to provide improved properties such as adhesion, flexibility, and compatibility of other components. For example, U.S. Patent Application No. 2007/0224140 A1 describes a composition comprising a cosmetically acceptable medium, a non film-forming microsphere to provide adhesion, and a film-forming component comprising two water-borne emulsion polymers. French Patent Application No. FR 2 968 978A describes an eyeliner composition comprising at least two film-forming latexes and a plasticizer to increase the flexibility of the film. French Patent Application No. FR 2 898 050A describes a composition comprising a fatty acid ester, and a copolymer of a (meth)acrylate polymer and a hydroxyester (meth)acrylate. U.S. Patent Application No. 2009/0297467A describes a composition comprising at least one neutralized sulfonated polymer and mixtures of acrylates and hydroxyester acrylates. U.S. Patent Application No. 2009/035335 A1 describes a mascara composition comprising two water-dispersible acrylate polymers, and a cross-linked polymeric film-former to enhance the compatibility and bind the two water-dispersible acrylate polymers. International Patent Application No. WO 2011/137338 A2 describes a composition comprising a polyurethane dispersion and an acrylic film-forming dispersion. U.S. Patent Application No. 2004/0071646A describes an aerosol device containing a composition comprising a polyurethane dispersion having a particle size of from 0.1-1 μm, and at least one non-latex fixing polymer.
Compositions for use in mascaras may have low glass transition temperatures (“Tg”) to obtain a soft film. For example, U.S. Patent Application No. 2010/0028284 A1 describes a mascara composition comprising at least two acrylate film formers, where the glass transition temperature (“Tg”) of the mascara composition is 20° C. U.S. Patent Application No. 2006/134043A describes a mascara composition comprising a fatty acid and at least one acrylate resin emulsion.
However, it has now been discovered that by providing a composition comprising at least two latex polymers, wherein at least one of said latex polymers is a film-forming polymer, and at least one component chosen from coalescing agents and plasticizers, it is possible to form a film on a substrate that has certain desirable properties, such as a clean, natural, and/or “invisible” feel, and a lack of stickiness. Such compositions may be useful in hair-styling applications wherein styling benefits such as a natural look, curling or straightening, and styling hold are imparted to hair.
The disclosure relates, in various embodiments, to compositions comprising at least two latex polymers, wherein at least one latex polymer is a film-forming polymer, and at least one component chosen from coalescing agents and plasticizers.

For instance, cosmetically acceptable organic solvents may be chosen from lower monoalcohols, such as those containing from about 1 to 5 carbon atoms, for example ethanol and isopropanol; polyols, including glycols, such as those containing from about 2 to 8 carbon atoms, for example propylene glycol, ethylene glycol, 1,3-butylene glycol, dipropylene glycol, hexylene glycol, and glycerin; hydrocarbons, such as, for example, isododecane and mineral oil; and silicones, such as dimethicones, cyclomethicones, and cyclopentasiloxane; as well as mixtures thereof.
A strip of regular bleached hair (from HIP, 7 cm long, about 0.5 g of hair) was treated with the latex solution (0.75 g of solution/g hair). The hair was combed through with a fine-toothed comb 10 times (10 seconds) on one side and 10 times (10 seconds) on the other side of the swatch until the solution was uniformly distributed over the surface of the tress. The treated hair was immediately mounted on the texture analyzer.
Three-point bending measurements were conducted using a texture analyzer (Model TA-XT2, Texture Technologies Corporation) equipped with a hair mounting accessory as described in J. Cosmet. Sci., 53, 345-362 (November/December 2002). The cantilever bending experiment consisted of the following sequence of steps: the hair tress was placed on a 2-point of 4 cm width, and the probe, representing the third point, came down at the middle of the hair tress and performed a 2-mm deformations of the hair tress. The testing protocol was:
Example 1: Evaluation of Effects of Coalescing Agents on Hardening Rate
Coalescing Range Increase
Sample Agent Slope R2 (g) in Force
1a 0% 0.2720 0.99 11.77-23.16 97%
1b 0.3% 0.3087 0.99 10.18-23.16 99%
1c 0.6% 0.3452 0.97 10.26-20.48 127%
These results show that as the amount of the coalescing agents in the latex solution increases, the film on the hair hardens at an increasing rate.
Example 2: Evaluation of Effects of Coalescing Agents on Hardening Rate
Hair tresses were treated with 2% solutions of LUVIFLEX® SOFT (INCI name: Acrylates copolymer, Young's Modulus of 2758 MPa and strain, under stress at 0.5 MPa, of <0.01%) and BAYCUSAN® C1001 (INCI name: Polyurethane-34, Young's Modulus of 3 MPa and strain, under stress at 0.5 MPa, of 18.82%) at 1:1 latex polymer ratio containing 0%, 0.3% and 0.6% of DOWANOL™ PNB. The film hardening rates are shown in Table 2 below.
2a 0% 0.5108 0.99 8.85-27.49 210%
2b 0.3% 0.7370 0.98 12.88-40.53 214%
2c 0.6% 0.8843 0.98 10.01-42.52 324%
These results show that as the amount of the coalescing agent in the latex solution increases, the film on the hair hardens at an increasing rate.
Example 3: Evaluation of High Humidity Curl Retention
Hair swatches were treated with 2% solutions of DAITOSOL 5000AD and NEOREZ® R989, or LUVIFLEX® SOFT and BAYCUSAN® C1001, at 1:1 latex polymer ratio containing 0%, 0.3% and 0.6% of DOWANOL™ PNB. The high humidity curl retention results are shown in Table 3 below.
Sam- Coalescing Curl
ple Latex (1:1) Agent Retention
3a NEOREZ R989:DAITOSOL 5000AD 0% 72%
3b NEOREZ R989:DAITOSOL 5000AD 0.3% 72%
3c NEOREZ R989:DAITOSOL 5000AD 0.6% 73%
3d LUVIFLEX SOFT:BAYCUSAN C1001 0% 86%
3e LUVIFLEX SOFT:BAYCUSAN C1001 0.3% 87%
3f LUVIFLEX SOFT:BAYCUSAN C1001 0.6% 87%
These results show that addition of the coalescing agent improves the curl retention at high humidity at the rates shown, compared to compositions not comprising coalescing agents.
