Description

Technical Field

[0001] This disclosure relates to a multi-peak hair care composition comprising a cationic guar gum blend and a method for preparing the same. Background Technology

[0002] Hair is a keratin fiber that withstands a variety of repetitive stresses, including mechanical stress from daily grooming (such as frequent brushing and combing), environmental stress (such as UV exposure), damaging chemical treatments (such as bleaching and dyeing), and thermal damage from the use of hot styling tools. These damaging effects often manifest in various types of damage to the hair fiber, including structural degeneration of the cortex, cuticle lifting, split ends, and other damaging effects that frequently lead to further damage and breakage. Hair care and styling formulators are constantly seeking products with multi-functional benefits that effectively treat and style hair. Synthetic and naturally derived polymers are widely used to achieve the desired sensory properties in hair care. Hair styling and conditioning products utilize both fully synthetic and naturally derived polymers to achieve conditioning and setting benefits. Consumers and formulators are seeking sustainable, environmentally friendly (such as biodegradable) and naturally derived solutions. Many traditional synthetic hair care and styling polymers do not meet sustainability standards set by governments and non-governmental organizations. Therefore, manufacturers of hair care and styling products face increasing pressure to formulate products using naturally derived, sustainable, and biodegradable ingredients while delivering the expected care and styling benefits. Due to the growing demand for sustainable ingredients, the hair care industry is shifting from synthetic chemicals to biodegradable, naturally derived, plant-based chemicals. Polysaccharides, a class of naturally derived polymers with excellent sustainability properties, are commonly used in rinse-out formulations (especially shampoos) to provide conditioning and deposition of active ingredients.

[0003] U.S. Patent No. 11,052,033, assigned to Rhodia Operations, discloses a personal care composition comprising a guar gum derivative having a weight-average molecular weight of about 250,000 g / mol to about 600,000 g / mol and guar gum hydroxypropyltrimethylammonium chloride having a cation substitution degree of about 0.20 to 0.30.

[0004] The inventors of this application sought to prepare hair care compositions using naturally derived and biodegradable cationic guar gum blends. Therefore, the applicant discloses cationic polysaccharides traditionally used in rinse-out formulations that provide excellent styling and conditioning benefits for hair. By combining cationic polysaccharides with high weight-average molecular weights and varying degrees of substitution, it is possible to customize formulations with styling and conditioning benefits. The combination of polysaccharides with different chemical properties allows formulators to “precisely control” performance and aesthetic properties important to consumers, such as hair stiffness, conditioning effect, slippage, moisture resistance, styling flexibility, and styling durability. Furthermore, cationic polysaccharides also help repair split ends, resist heat and mechanical damage, and protect hair from damage caused by hot straighteners at temperatures up to 450°F.

[0081] Hair characteristics A 0.50 g test sample was applied to a clean, damp hair bundle (International HairImporters; Black Indian / Asian, 3.5 g, 2.5 cm wide, 25 cm long), and wound onto a 2.5 cm roll. It was then dried in a 48°C oven for 1 hour and placed overnight at 50 RH and 22°C ± 2°C. The roll was removed, and the hair bundle was suspended on an evaluation board with the clips removed. The initial hold, hold after the 5th compression, hold after the 10th compression, combing resistance, frizz control, and static were evaluated on a scale of 1-10. A score of 8.0 ± 1.0 for stiffness, combing resistance, frizz control, and static, and a stiffness score of 7.0 ± 1.0 after the fifth and tenth compressions, were considered acceptable. Results are as follows: Figure 1 As shown.

[0082] High humidity curl retention rate Apply 0.50 g of the test prototype sample to a clean, damp hair bundle (International HairImporters; Black Indian / Asian, 3.5 g, 2.5 cm wide, 25 cm long), and wind it onto a 2.5 cm roll. Dry in a 48°C oven for 1 hour, then overnight at 50 RH and 22°C ± 2°C. Remove the roll and suspend the hair bundle on a horizontal marker marked with a 1.00 cm mark in a high-humidity environment (90% RH, 27°C). The moisture resistance after 24 hours is calculated using the following formula: (Lo – Lt ) / (Lo – Li) × 100 (at time t) Where: Lo = hair length when fully extended Li = Initial hair length before exposure. Lt = Hair length after exposure time (t).

[0083] The results are listed below.

[0084] Table 6

[0085] It was observed that the hair curl retention rate of samples using the cationic guar gum blend of the present invention exceeded 98% after 24 hours, such as... Figure 2 As shown.

[0086] Curl compression A 0.50 g test sample was applied to a clean, damp hair bundle (International HairImporters; Black Indian / Asian, 3.5 g, 2.5 cm wide, 25 cm long) and wound onto a 2.5 cm roller. It was then dried in a 48°C oven for 1 hour and placed overnight at 50 RH and 22°C + / - 2°C. The roller was removed, and the hair bundle was secured to the curling compression accessory of a Diastron MTT 175. The total maximum glyph was measured through five rounds of testing, with each test sample repeated three times. Higher glyph indicates higher hair stiffness. Results are as follows: Figure 3 As shown, the specific numerical list is as follows.

[0087] Table 7

[0088] The average value of the curl compression was observed to exceed 270.

[0089] Three-point bending test A 0.35 g test sample was applied to a clean, damp hair strand (International HairImporters; Black Indian / Asian, 2.5 g, 2.5 cm wide, 16 cm long) and placed on a flat steel plate. It was dried in an oven set to 48°C for 1 hour and then left overnight at 50 RH and 22°C + / - 2°C. The next day, the dried hair strand was gently placed on the three-point bending fitting of a Diastron MTT 175. The total maximum grit value was measured through five rounds of testing, with each test sample repeated three times. Higher grit indicates better stiffness. Results are as follows: Figure 4 The results are shown in the figure and listed below.

[0090] Table 8

[0091] Therefore, we observed that cationic guar gum blends with high weight-average molecular weight exhibit a wide range of tribological properties compared to individual samples, while allowing for optimization of usage levels, weight ratios, and mw / ds to provide improved elastic hair texture characteristics superior to commercial controls. Furthermore, the compositions of the present invention comprising cationic guar gum blends with high weight-average molecular weight offer advantages over prior art compositions, as manifested in the following ways: (i) Helps improve hair styling characteristics such as combing resistance, frizz control, and stiffness, such as Figure 1 As shown; (ii) Higher density indicates that the styled hair has better stiffness, such as Figure 3 and Figure 4 As shown; (iii) Provides a clearer, more flexible curl.
