Description

Title of the invention: HAIR CARE SERUM COMPOSITION FIELD OF INVENTION

[0001] The present invention relates to a hair care serum composition. The hair care serum composition comprises at least two polymers, at least one silicone, at least one amidoamine, at least one organic acid, at least one cationic surfactant, and at least one nonionic surfactant. The present invention also relates to a method for treating and reconstructing hair and for using a hair care serum composition. CONTEXT OF THE INVENTION

[0002] In the field of cosmetic treatment of keratinous fibers, in particular human keratinous fibers, and more particularly hair, consumers desire hair care treatments that can impart moisture and rebuild damaged hair, which can improve the appearance of frizzy hair.

[0003] The quality and condition of hair are generally negatively affected by several factors, such as the action of external agents like sunlight, wind, pollution, humidity, and chemicals in swimming pools, as well as by mechanical or chemical treatments, such as brushing, combing, shampooing, dyeing, bleaching, perming, and / or straightening. Hair is thus damaged by these various factors and can, over time, become dry, rough, or dull, particularly in fragile areas and especially at the ends, leading to split ends. Under such circumstances, hair can also become less manageable, frizzier, less disciplined, and more difficult to style or shape.

[0004] We seek to treat and rebuild keratinous fibers that have been sensitized and / or damaged, in particular to treat keratinous hair fibers that have an opaque, dull, brittle, lifeless and / or fragile appearance, as well as dry and split ends.

[0005] Cellulose and gums are used to achieve various objectives in a formulation, which may be related to film formation, stability, texture, etc. Silicones, for the most part, are related to the appearance of cosmetics, film formation, shine, etc. In most products developed for hair care, it is common to find some type of cellulose, which may sometimes be combined with a gum. When the gum is cationic, it is rarely used in products with Rinse, because after rinsing, the gum filler will interact well with water and may be removed from the yarn, thus wasting its presence in the initial formulation.

[0006] One way to reduce friction and achieve high fiber coverage performance is to invest in film-forming polymers; however, the combination of more than two polymers for this purpose is rarely observed in the literature and products.

[0007] Following the consumer movement in the treatment category towards a more liquid and fluid texture with knowledge of skin care and the ideal balance of hair care ingredients, an objective of the present invention is to offer an alternative hair care experience with a new sensoriality to hair care routines and immediate reconstructive effects: strengthened and aligned hair, without stiffness and shiny.

[0008] Although care products that address these problems already exist on the market, the hair care system of the present invention provides improved results for hair, including improved manageability, discipline, detangling, softness and cleanliness, satisfaction with repair and texture, control of frizz or less frizz, and less brittle hair. Summary of the invention

[0009] The invention relates to a skincare serum texture for a hair care product designed to repair hair and regenerate hair moisture without leaving it greasy, oily, or weighing it down. The product can be used as a rinse-off or leave-in treatment.

[0010] The hair care serum composition of the present invention contains a combination of polymers and care ingredients, the formulation of which may be related to film formation, stability, textures, etc.

[0011] It was surprisingly discovered that the use of two celluloses of different molecular weights could associate and form intertwined structures. When added to a cationic gum and a mixture of two types of silicones, the deposition of this entire silicone polymer complex becomes rapid, strong, and individually uniform on the fiber. The presence of a positively charged silicone at acidic pH enhances the deposition initiated by the cationic guar gum, as amodimethicone and gum silicone will both have a high affinity for the damaged yarn, since the yarn is predominantly negatively charged. The high molecular weight of the other silicone, dimethicone, also enhances the deposition by intertwining with other polymer chains. Consequently, the considerable increase in the weight of the structure also results in high slippage (less friction) and neutralization. loads, a larger coverage area and resistance to rinsing.

[0012] Instrumental tests show that the invention significantly increases the flexibility of damaged yarn, which can result in greater strength. Expert and laboratory tests show that the formulation has an immediate effect on yarn transformation and coverage, generating high fiber alignment in both wet and dry applications. From this, it can be suggested that there is an increase in yarn weight due to the deposition of the silicone polymer complex and the ease of drying, as the yarn becomes more hydrophobic. The excellent results of both rinse-on and leave-on products demonstrate that the formulation is versatile and unique.

[0013] In general, rinse-off products are different from leave-on products, but the present invention has proven that a single formulation can have excellent results in these very different scenarios.

[0014] Other subjects and features, aspects and advantages of the present invention will become even clearer upon reading the detailed description and examples that follow. DETAILED DESCRIPTION OF THE FIGURES

[0115] Example 9 - Composition of the state of the art

[0116] A comparative state-of-the-art composition may include the following ingredients:

[0117] [Table 2] Comparative formulation of the state of the art Ingredient Function Ex. 9 Behentrimonium Chloride Surfactant 0.60 Quaternium-87 Surfactant 3.35 Modified Potato Starch Polymer 1.00 Polysorbate 20 Surfactant 0.80 Chlorhexidine Dihydrochloride Preservative 0.02 Phenoxyethanol Preservative 0.50 Fragrance Fragrance 0.80 Water Solvent 90.53 2-Oleamido-1,3-Octadecanediol Hair Conditioning Agent 0.40 Amodimethicone (and) Trideceth-6 (and) Cetrimonium Chloride Silicone 1.00 Stearyl Alcohol Fatty Compound 1.00 Qualitative test

[0118] Two prototype products were tested in two stages. The first time, users applied the inventive composition of Ex. 1 after shampooing and waited for it to act for 5 minutes, then rinsed the product and optionally used a conditioner or mask. This routine was based on one of the liquid keratin routines. The second time, users were free to choose their routine.

[0119] During application, the inventive composition exhibited rapid absorption and easy application due to its fluid and lightweight texture, and also made detangling easy. Furthermore, the inventive composition provides hair with quick results, leaving it feeling soft, shiny, and bouncy, with less frizz and added volume at the ends. Therefore, users have indicated that the inventive composition can be used as a standalone treatment. Flexibility test

[0120] Two instrumental flexibility tests were conducted on a strand of straightened, dirty hair and a strand of bleached hair compared to a strand of natural hair as a reference. The objective of these tests was to evaluate the impact of the hair care serum composition of the present invention on hair flexibility after rinse-out treatments. The results can be seen in [Fig. 1] and [Fig. 2], where a high maximum force (N) indicated that the hair was straight and rigid, and a lower maximum force indicated that the hair was softer and more flexible.

[0121] Straightened and dirty hair exhibited less suppleness compared to the natural hair reference. After application of the composition of Ex. 1 to straightened and dirty hair, the hair exhibited a suppleness similar to that of natural hair.

[0122] The bleached hair also exhibited lower suppleness compared to the natural hair reference. After application of the composition of Ex. 1 to bleached hair, the hair exhibited a suppleness similar to that of natural hair.

[0123] The inventive composition of Ex. 1 restored the suppleness of straightened and dirty hair and bleached hair of 28% and 27%, respectively. Comparative tests

[0124] The performance of the hair care composition according to Ex. 1 and the composition according to Ex. 9 (state of the art) was compared in a qualitative trial conducted with consumers with damaged hair, users of reconstructive treatments and hair types I to IV. For the first two uses, consumers applied the compositions to wet hair after washing it with shampoo and left them on for 5 minutes, then rinsed their hair.

[0125] The composition of the present invention gave more body and texture to the hair, a silky, smooth texture and shine, a feeling of hydrated and repaired hair, fortified hair, an easy-to-spread / dosage texture, pleasant and no feeling of stiffness during application, compared to the composition of the state of the art.
