Patent Application
20180243199
The present application relates to a personal care composition, and, more particularly, to a personal care composition comprising a conditioning and/or styling copolymer for a keratin substrate of hair and/or skin origin.
A particular challenge for a personal care product developed for damaged hair is to condition hair damaged by heat, or damaged mechanically or chemically through bleaching or coloring the hair. Consumers desire to have existing damage to the hair be repaired and to prevent further damage to the hair from occurring. It is desired that conditioned hair be easily manageable, feel-smooth, and be easy to detangle. However, if hair is over-conditioned, the hair is perceived as being weighed down.
Silicones are traditionally used in hair care applications to provide conditioning properties such as ease of combing and detangling, color retention, smoothness and hydrophobicity. Silicones function by forming a film on the hair surface and depending on the nature of the silicone they are either self-deposited or they require additional cationic ingredients for deposition. It is desired to formulate conditioning systems having reduced or no silicones while still providing silicone's benefits. The conditioning composition presented in the invention provides improved or similar properties to silicones and can also be used in the applications formulated without silicones.
The IP.com prior art database technical disclosure no. 000242076 reveals a personal care conditioning and/or styling composition for a keratin substrate comprising: (i) about 0.1 wt. % to about 20 wt. % of PolyAPTAC polymer; (ii) about 0.1 wt. % to 99.9 wt. % of water; (iii) at least one cosmetically acceptable excipient; (iv) optionally, about 0.1 wt. % to about 1 wt. % of one or more natural or synthetic based monomer or polymer selected from the group consisting of anionic, cationic, non-ionic, amphoteric, hydrophobic, or zwitterionic in nature; and (v) optionally, at least one personal care active ingredient.

The examples are presented to illustrate the invention, parts and percentages being by weight, unless otherwise indicated.
Further, certain aspects of the present invention are illustrated in detail by way of the following examples. The examples are given herein for illustration of the invention and are not intended to be limiting thereof.
Phase A, B, C and D were prepared as per the w/w compositions of Tables 1 & 2. Phase A is first prepared and ingredients mixed together until homogenous at 70-80° C. Phase B is separately formulated at 70-80° C. and ingredients mixed together until homogenous—then added to Phase A and homogenized with a high shear mixer and cooled down to approx. 40° C. Then Phase C & D ingredients added & mixed until homogenous.
Each of these phases were used to prepare Examples a, b, c, d, e, f, g, h, i, j, k, l and m, wherein sample “m” is formulated where the poly APTAC polymer was added in the Phase C as “cold phase” to further improve the performance of the hair care product, and samples “f” and “l” are mix PQ37 and Poly APTAC polymer without additional rheology modifiers added.
Wet Combability Study
The PolyAPTAC polymer was tested as a 1 wt. % in 2.5% fatty alcohol and 0.7 wt. % Cationic surfactants (Example “b” of Table 1). As a reference 1 wt. % Polyquaternium-37 in 2.5 wt. % fatty alcohols and 0.7 wt. % cationic surfactants was used (Example “a” of Table 1). To study a combination of PolyAPTAC and Polyquaternium-37 two examples were used. Example “c” consists of 0.25 wt. % PolyAPTAC polymer and 0.25 wt. % Polyquaternium-37 polymer in 2.5% fatty alcohol and 0.7% Cationic surfactants. Example “d” consists of 0.5 wt. % PolyAPTAC polymer and 0.5 wt. % Polyquaternium-37 polymer in 2.5 wt. % fatty alcohol and 0.7 wt. % Cationic surfactants. The conditioner was applied on damaged hair (0.2 grams per gram of bleached hair, 1 hour bleached) and wet comb energies were measured with Texture Analyzer after the rinse with water and after 1, 3 and 5 times of washing with 0.1 grams per gram hair shampoo (shampoo: 12/2 SLES/CAPB). The test results are provided in Table 3:
From the above results presented in Table 3, it was evident that a PolyAPTAC polymer when used in combination with Polyquaternium-37 provides better performance compared to the conditioning polymers alone. There is a clear synergy between the polymers resulting lower wet comb energy values. As seen in Table 3, the wet combing energy after 5 washes (gf-mm) was 21,688 for example “a” (formulated with 1 wt. % Polyquaternium-37), 17,247 for example “b” (formulated with 1 wt. % PolyAPTAC polymer) and only 10,596 for example “d” (formulated with combination of 0.5 wt. % Polyquaternium-37 and 0.5 wt. % PolyAPTAC polymer). These examples are clear indication of providing additional long lasting conditioning benefits when combining both Polyquaternium-37 and PolyAPTAC polymer.
The PolyAPTAC polymer was tested as a 1 wt % in 2.5% fatty alcohol and 0.7% Cationic surfactants (Example “b” of Table 1). As a reference 1 wt. % Polyquaternium-37 in 2.5% fatty alcohol and 0.7% Cationic surfactants was used (Example “a” of Table 1). Example “e” of Table 1, consists of 0.25 wt. % PolyAPTAC polymer and 0.25 wt. % Polyquaternium-37 polymer in 2.5% fatty alcohol and 0.7% Cationic surfactants and 0.1 wt. % Natrosol Plus 330. Rheology profile Viscosity vs. Shear stress of above mentioned examples was measured with Anton Paar Rheometer. The results are provided in
