Description

[Technical Field]

[0001] This invention relates to a hair care formulation. Specifically, this invention relates to a hair care formulation containing a conditioning polymer, wherein the conditioning polymer is -Si(R 1 ) Contains a maltodextrin-based polymer functionalized with three groups, in the formula, each R 1 Independently, C 1~10 The maltodextrin-based polymer is a linear or branched saturated alkyl group, and has 1 to 24 dextrose equivalents (DE), while the conditioning polymer has 1.7 to 3 -Si(R) 1 The conditioning polymer has three degree of substitution (DS) groups and does not contain vinyl carbon.

[0002] Conventional hair conditioners are popular with consumers for treating hair. Silicone-based conditioning agents are the most commonly used conditioning agents in hair conditioner formulations. However, there is growing concern among some consumers regarding the persistence and potential toxicity of certain conventional silicone-based conditioning agents in the environment, or the trace compounds incorporated into such conventional silicone-based conditioning agents, particularly with regard to D4 and D5 conditioners. Therefore, there is growing interest in the development of new conditioning agents for use in hair conditioner formulations.

[0003] In U.S. Patent No. 5,879,670, Melby et al. disclose a non-silicone-containing amphoteric electrolyte polymer for use as a conditioning agent for the treatment of keratin-containing substrates. In particular, Melby et al. disclose (meth)acrylamidopropyltrimethylammonium chloride, meth(acrylic acid) or 2-(meth)acrylamido-2-methylpropanesulfonic acid, and optionally C 1~22Disclosed are novel conditioning polymers containing alkyl (meth) acrylates and their use in a cosmetically acceptable medium for the treatment of keratin-containing substrates (preferably mammalian hair, more preferably human hair).

[0004] Nevertheless, there remains a continuing need for novel hair conditioning agents that provide conditioning benefits. There is also a continuing need for new hair conditioning agents that have a high bio-carbon content compared to conventional hair conditioning agents.

[0005] The present invention provides a hair care composition comprising a conditioning polymer, the hair care composition comprising a maltodextrin-based polymer functionalized with -Si(R 1 )3 groups, wherein each R 1 is independently a C 1~10 linear or branched saturated alkyl group, the maltodextrin-based polymer having a dextrose equivalent (DE) of 1 to 24, the conditioning polymer having a degree of substitution (DS) of 1.7 to 3 -Si(R 1 )3 groups, and the conditioning polymer being free of vinyl carbon.

[0006] The present invention provides a method of conditioning hair, comprising selecting the hair care composition of the present invention, wetting a plurality of mammalian hair strands with water, and applying the hair care composition to the wet plurality of hair strands to provide a plurality of treated hair strands.

[0053] Comparative Examples CF1-CF2 and Example F1: Hair Conditioner Formulations Hair conditioner formulations containing the ingredients listed in Table 4 were prepared in each of the Comparative Examples CF1-CF2 and Example F1.

[0054] [Table 4]

[0055] Hydrophobicity of hair The hair conditioner formulations prepared according to Comparative Examples CF1-CF2 and Example F1 were tested on separate 4g hair strands (a series of bleached hair from DeMeo Brothers, Inc., lot 4506145707). The hair strands were first rinsed with water for 30 seconds. Then, a 9% (weight / weight) aqueous solution of sodium lauryl sulfate (0.2g per gram of hair) was massaged into the hair strands for 30 seconds. The hair strands were then rinsed with water for 60 seconds. The hair strands were then treated with hair conditioner at a rate of 0.15g / g or the amount of hair, and massaged into the hair for 1 second.

[0056] To measure the hydrophobicity of the hair, strands of hair were combed straight and then held firmly at both ends with a holder. Ten drops of water (30 μL per drop) were placed at different locations on each strand of hair, from root to tip, and observed. Drops of water placed on a strand of hair treated with the formulation of Comparative Example CF1 were observed to dissipate immediately from the surface of the strand. Drops of water placed on a strand of hair treated with the formulation of Comparative Example CF2 were observed to dissipate from the surface of the strand within approximately 2 minutes after application. Drops of water placed on a strand of hair treated with the formulation of Example F1 were observed to remain on the surface of the strand for at least 10 minutes after application before dissipating into the hair.

[0057] Drying time Hair conditioner formulations prepared according to Comparative Examples CF1, CF3-CF4, and Example F1 were tested on separate 4g hair bundles (a series of bleached hair bundles from DeMeo Brothers, Inc., Lot 4506145707). The hair bundles were first rinsed with water for 30 seconds. Then, a 9% (weight / weight) aqueous solution of sodium lauryl sulfate (0.2g per gram of hair) was massaged into the hair bundles for 30 seconds. The hair bundles were then rinsed with water for 60 seconds. The hair bundles were treated with hair conditioner at a rate of 0.15g / g or the amount of hair, and the hair was massaged for 1 second.

[0058] The drying time of treated hair strands suspended in a controlled atmosphere at room temperature (21°C) and relative humidity of 50% was evaluated. Hair strands treated with the formulation of Example F1 were observed to have a shorter drying time without causing frizz compared to other hair strands treated in Comparative Examples CF1 and CF3-CF4.

[0059] Curl control Hair conditioner formulations prepared according to Comparative Examples CF1, CF3-CF4, and Example F1 were tested on separate 4g hair buns (bleached cylindrical hair buns from DeMeo Brothers, Inc., Lot 4506145707). The hair buns were first rinsed with water for 30 seconds. Next, a 9% (weight / weight) aqueous solution of sodium lauryl sulfate (0.2g per gram of hair) was massaged into the buns for 30 seconds. Then, the buns were rinsed with water for 60 seconds. The buns were treated with hair conditioner at a rate of 0.15g / g or the amount of hair, and the hair was massaged for 1 second.

[0060] Next, the treated hair tufts were suspended and dried for 24 hours in a controlled atmosphere at room temperature (21°C) and 50% relative humidity.

[0062] Reducing static electricity Hair conditioner formulations prepared according to Comparative Examples CF1, CF3-CF4, and Example F1 were tested on separate 2g hair bundles (dark-bleached hair bundles from International Hair Importers, Inc., lot 4507227801). The hair bundles were first rinsed with water for 30 seconds. Then, a 9% (weight / weight) aqueous solution of sodium lauryl sulfate (0.2g per gram of hair) was massaged into the hair bundles for 30 seconds. The hair bundles were then rinsed with water for 60 seconds. The hair bundles were treated with hair conditioner at a concentration of 0.15g / g or the amount of hair, and the hair was massaged for 1 second.

[0063] Next, the treated hair strands were suspended and dried for 24 hours in a controlled atmosphere at room temperature (21°C) and 50% relative humidity. Then, each treated hair strand was passed very quickly between the index and middle fingers, and a photograph was immediately taken for comparison. The hair strands treated in Comparative Example CF1 and Comparative Example CF4 were observed to exhibit the highest static electricity. The hair strands treated in Comparative Example CF3 and Example F1 were observed to exhibit significantly lower static electricity.

[0074] Comparative Examples CF7-CF9 and Examples F6-F10: Water-repellent The water repellency of a film is strongly influenced by surface energy. High water repellency is desirable for skincare applications. The water repellency of a formulation can be evaluated by measuring the water contact angle from the deposited film of the formulation. Specifically, the film was coated onto a glass slide (wet thickness of 50 μm) using a doctor blade film applicator with a gap set to 6 mil (0.1524 mm) from the as-received polymer solution, using a dispersion formed with the components listed in Table 10. The film was then air-dried in an environmentally controlled chamber (22°C and 50% RH) for at least 72 hours. Water droplets were then deposited onto the substrate using a droplet shape analyzer (Kruss DSA100), and the water contact angle of the deposited film was measured at 4 seconds and 120 seconds (in degrees). The results of the water contact angle measurement are shown in Table 10. A larger contact angle indicates higher water repellency. A contact angle greater than 90° is considered excellent.
