Description:
A HAIR CARE COMPOSITION, PROCESS FOR PREPARING

THE SAME AND METHOD OF USE THEREOF

FIELD OF THE INVENTION

[0001] The present application relates to a hair care composition having a pH of about 5 to 11, and more particularly, to a hair straightening or hair styling composition comprising a lactone, a base and a carrier optionally, in combination with a hydroxy ketone, a functional polymer, a base, a diol, a polyol, a sugar, a reducing agent and/or an amino acid. The present application further relates to a method of preparing the hair straightening or styling composition and the use thereof.

BACKGROUND OF THE INVENTION

[0002] Hair straightening or styling has become increasingly popular in view of hair styles which require relatively or perfectly straight hair. Hair protein, keratin forms a long helical chain like a very thin strand of rope. Groups of these thin strands form filaments. Groups of filaments, in turn, form the bulk of the hair strand's inner layer, called the cortex. Hair straighteners change how strands of keratin stick together. Different hair straightening methods target various chemical connections that hold keratin strands together.

[0003] Several types of hair straightening products currently used include formaldehyde, glyoxylic acid, dimethyl urea, a-hydroxy acids and amides, a-keto acids combined with amides, and glyoxylic amino acids such as carbo cysteine.

[0004] U.S. Patent No. 9,138,599 assigned to L'Oreal discloses a waving composition for waving of a keratinous fiber comprising ammonium bisulfite, ammonium sulfate or urea and <5-gluconolactone.

[0005] U.S. Published Application No. 20130074862 assigned to L'Oreal S.A. discloses a process of straightening or relaxing hair by pre-alkalizing the hair before treating the hair with weak non-hydroxide base and oil. Weak inorganic bases include alkali metal phosphates and carbonates.

[0006] Brazilian Patent Application No. PI1101006 discloses the use of hydroxyacetone at a recommended pH range of 1.0 to 3.0 when applying to the hair. This highly acidic pH range is corrosive and degrades the hair fiber by hydrolysis of the native proteins in hair. Individuals with oxidatively dyed hair cannot use this treatment as the highly acidic pH affects and reacts with the dyes and results in an obvious and unwanted color change in the dyed hair even before the heat activation step. Moreover, this extreme pH is also very irritating to the skin and scalp, and requires a professional salon to apply it to prevent contact with the skin. This can result in excessive fees charged to the consumer in the salon to maintain a safe application/treatment onto the consumer.

[0007] PCT Publication No. WO2014152455 Al discloses a method of providing shape memory to fibers employing chitosan and poly(e-caprolactone) along with a crosslinking agent.

[0008] The various prior art techniques employ either low pH or high pH conditions, formaldehyde sprays, are non-regulatory friendly, require long processing times and unsafe procedures thus causing serious damage to the scalp and hair.

[0009] In view of the foregoing, there remains a need for a safe hair care composition with a long lasting straightening effect and shorter processing time.

[0059] The functional silicones can be selected from the group consisting of silicone quat, silicone fluid and silicone wax. These silicones are able to decrease friction during hair combing and flat ironing, smooth gliding; increase conditioning and smoothing to hair by adding flexibility; help reducing heat damage and style retention; contributes to shine depending on the refractive index.

[0060] The oxidizing agents can be selected from, but are not limited to, hydrogen peroxide, bromides and peracetic acid to fix the disulfide bond back.

[0061] The conditioning agents can be selected from, but are not limited to, polymeric and small quaternary ammonium compounds such as tertiary amines quaternium and polyquaternium compounds.

[0062] The humectants can be selected from, but are not limited to, glycols, sugars, oils, silicones, emollients and proteins. These humectants create a cage effect by adding moisture to the hair.

[0063] The pH adjusting buffer can be selected from, but are not limited to, glyoxylic acid, maleic acids, succinic acid, formic acid and other organic and inorganic acids. These buffers promote active penetration of the composition of the present application and facilitate the reactions if any for effective results of the composition.

[0064] The preservatives can be selected from, but are not limited to, propylene glycol, urea, paraben, methyl paraben, phenoxyethanol, caprylyl glycol, glycol dicaprylate/Dicaprate, iodopropynyl butyl carbamate, and diazolidinyl urea.

[0065] According to another embodiment of the present application, a catalyst is employed to facilitate the reaction speed of active ingredients. Suitable catalyst can be non metallic (N-methylimidazole, Perfluoroalkanesulfonates, N-dimethylaminopyridine) or metallic (tin, aluminum, iron, scandium, yittrium, zinc, bismuth, ruthenium, zirconocene) in nature. [0066] Further, the composition of the present application also may comprise fatty alcohols or waxes as structuring agents, anionic or non-anionic surfactants or wetting agents, petrolatum as thickeners or protectants, mineral oils as lubricating agents, mica or silicas, bentonite, or other inorganic powders as thickening agents and heat transfer agents.

[0067] In another non-limiting embodiment, the present application discloses a hair care composition which is capable of styling, straightening or conditioning hair by providing "virgin feel condition" to the hair after multiple washes, particularly providing at least one of the following results, including (1) increased hydrophobicity, (2) improved detangling and wet combability, (3) improved deposition, and (4) no build-up.

[0068] In another non-limiting embodiment, the present application discloses the synergy of caprolactone that enables hair straightening, hair styling or hair conditioning to last for longer duration. The synergistic combination of (i) caprolactone alone or in combination with at least one hydroxy ketone, (ii) functional polymer, (iii) reducing agent, (iv) diol, polyol, sugar, and (v) at least one organic or inorganic base component facilitates the penetration of the composition into the hair fiber's cortex and modifies the hair fiber's natural shape. Styling polymer, thickening polymer, conditioning polymer or biopolymer will react with itself and/or with the straightening components lactone and hydroxy ketone to be semi-permanently affixed to hair and survive multiple shampoo cycles. In doing so, the hair tress will have significant improvement in providing or enhancing life to it and limp and still maintain same desired aesthetic attributes like shine, conditioning, luster, and feel, etc. After thermal activation and styling, these polymers are semi-permanently affixed to the hair and these effects will last a minimum of 10 shampoo and conditioning cycles when using the most harsh sulfate based shampoos. Even longer lasting results are obtained when non-sulfate based shampoos are used as known to those skilled in the art, generally around 30 shampoo cycles. Furthermore, thermal activation of the composition does not produce formaldehyde or noxious vapors to achieve these effects and thereby provides a safer alternative to the formaldehyde-based "Brazilian Blowout" treatment that is currently being banned across the globe.

[0069] Without being bound by the theory, it is further contemplated that the functional polymer further aids in permanent fixation onto the hair fiber. These polymers include acidic, alcoholic, thiol, or amino/amide bearing at least one hydrogen atom. The addition of diols and polyols will help increase hydroxyacetone penetration into hair and then create oligomers of polyketals with heat, which inhibit the penetration of water from outside to inside the hair. These molecules also react with the side chain of protein's amino-acids like lysine and arginine to create straighter hair (also crosslinks between keratin bundles). In addition, a three-fold increase in the rate of hair straightening was observed by diols, such as from 1 in/second to 3 in/second, flat iron rate. The presence of one or more of these groups on the straightening product will react with the straightening agents described to form a crosslinked matrix that remains affixed to hair for several shampoo cycles. The presence of the polymer and/or biopolymer on the hair after several shampoo cycles is quite evident by the feel of the treated fiber as compared to the control fiber containing all the same components, but lacking the polymer component in this composition.

[0070] In another non-limiting embodiment, the present application provides a hair straightening or hair styling composition comprising: (i) caprolactone alone or in combination with hydroxy acetone or dihydroxy acetone or both; (ii) sodium bicarbonate or propylene carbonate; (iii) at least one functional polymer, and (i) at least one carrier, wherein said composition has a pH of about 5 to about 11.

[0071] In yet another non-limiting embodiment, the present application provides a hair straightening or hair styling composition comprising: (i) about 0.1 to about 50.0 wt. % of at least one caprolactone, acetolactone, propiolactone, 1-butyrolactone, 2-methyl butyrolactone, 3-methyl butyrolactone, valero lactone or hexalactone alone or in combination with at least one hydroxyacetone or dihydroxy acetone or mixtures thereof; (ii) about 0.1 to about 20.0 wt. % of sodium bicarbonate or propylene carbonate; (iii) optionally, about 0.1 to about 20.0 wt. % of at least one functional polymer, and (iv) about 40.0 to about 80.0 wt. % of at least one carrier, wherein said composition has a pH of about 5 to about 11.

[0072] It is well known that if one uses basic neutralizers like NaOH, or sodium phosphates, the straightening effect is not that pronounced, whereas the present application discloses employing caprolactone alone or in combination with hydroxyacetone and sodium bicarbonate having long lasting straightening effect. Moreover, consumer safety is of premier importance, the neutral to slightly alkaline pH region for hair straightening is observed to be superior as compared to that of highly acidic or highly alkaline condition based straightening effects. The present hair styling composition can be applied on damp or dry hair, displays longer lasting straightening effects, shorter processing times as hair can be washed right away immediately once the hair is straightened unlike the formaldehyde treatment which requires long time, i.e. a waiting period, to wash the hair. Moreover, straightening does not damage the hair, and is safer to scalp and hair.

[0073] The present composition enables treatment of hair at wide pH ranges (pH=l-14). In another embodiment, the present composition enables treatment of hair in neutral to slightly alkaline conditions at pH=7-12 which is much safer and less corrosive to scalp and hair. The hair composition of the present application is employed for oxidatively dyed hair without extreme color changes that are observed by the other hair straightening treatments even before the thermal activation step is applied. In this regard, lower straightening temperatures with multiple passes are required to minimally affect the dye molecules need to be employed, and to provide some straightening effects.

[0074] In yet another non-limiting embodiment, within scope and contemplation, the present hair care composition comprising lactone alone or in combination with at least one hydroxy ketone, at least one organic or inorganic base, and optionally, at least one functional polymer can be advantageously employed in combination with hair care compositions that are known commercially and in relevant literature as prior art for a person skilled in the relevant art, and wherein, such non-limiting compositions that are known in the prior art include glyoxylic acid / dimethyl urea, polyacrylate cross polymer, polysaccharides, film forming agents and N-alkyl-2-mercaptoacetamide.

[0075] In yet another non- limiting embodiment, the present application discloses a method of straightening or styling hair, the method comprises: washing hair tresses with shampoo; eliminating or reducing the moisture of hair tresses of step (a); applying the hair straightening or styling composition comprising (i) about 0.1 to about 50.0 wt. % of at least one caprolactone alone or in combination of mono hydroxy acetone or dihydroxy acetone or both; (ii) about 0.1 to about 20.0 wt. % of sodium bicarbonate, ammonium carbonate or propylene carbonate; (iii) optionally, about 0.1 to about 20.0 wt. % of at least one functional polymer, (iv) optionally, about 0.1 to about 20.0 wt. % of at least one diol, polyol, sugar or combinations thereof; (v) optionally, about 0.1 to about 20.0 wt. % of at least one reducing agent; and (v) about 40 to about 80.00 wt. % of at least one carrier, wherein said composition has a pH of about 5 to about 11, to the dried or damp hair of step (b); leaving the treated hair for about 15 to 30 minutes for penetration; hot air drying the treated hair of step (d) by mechanically straightening hair with either brushing or combing with a slow uniform motion from root to tip; ironing the hair from step (e) using flat iron pre-heated to 375-450°F for at least 4 to 8 times; and allowing the hair tresses as of step (f) to remain as such for at least 15 to 20 minutes to obtain straightened or styled hair.

[0076] According to one embodiment of the present application, the hair tresses are selected from Caucasian, Asian and African origins selected from fine, medium and coarse virgin, damaged, colored, grey, bleached hairs, and wherein, the hair tress has textures comprising wavy, curly, coily or kinky patterns.

[0077] According to one important embodiment of the present application, the composition employs molecules which are much safer, allows the hair treatment for straightening, conditioning or styling to be performed at wide pH range of highly basic to highly acidic, and does not emit formaldehyde during the process, and is capable of providing long term hair straightening.

[0078] Advantageously, the hair straightening process of the present application provides hair styling and/or hair straightening that lasts for at least 10 to 30 hair washes even after using strong sulfate based shampoo and conditioner. Further, the combination of caprolactone, hydroxy ketone/s and organic/inorganic base penetrates into the hair fiber's cortex and modifies the hair fiber's natural shape. The functional polymer of the present application provides additional shape control, styling, shine, feel, conditioning and/or luster to the hair.

[0090] EXAMPLE 6: A Hair Straightening or Styling Method

[0091] Hair tress was washed thoroughly with shampoo and warm water (35-40°C) followed by second wash, and rinsed for 30 sec. Excess water was removed, and moisture was removed using blot with towel. Hair styling product of any of the above formulations of examples 1 to 4 was applied; through from root to tip with fingers and comb until uniformly distributed to remove excess. Treated hair was left for 30 minutes for the styling product to penetrate. (Hang tress in straight position). After 30 minutes, tress was hot blow-dried as straight as possible with much tension using a round brush or comb with slow uniform motion from root to tip. Flat iron was pre-heated and hair was treated with pre-heated flat iron from root to tip about six times. Allowed tress to equilibrate to lab conditions; Evaluated tress- State: Straightened. Washed hair tress with warm water (35-40°C) for 30 second wetting, 30 seconds wash (shampoo), and 30 seconds rinse. Hair was conditioned for 30 seconds, followed by 30 seconds rinse. After hair wash, hair was dried to see hair straightened.

[0092] The hair tresses after treating with styling product as described in Example 5 were subjected to hair washing and conditioning for about 10 cycles. The results are shown in Figure 1. It is observed that the styled or straightened hair remains in the same state even after 10 wash cycles.
