Description

Title of the invention: A process for treating keratin fibers using a composition comprising at least one specific fatty acid, at least one oxygenated terpene compound, and at least one modified polysaccharide. Technical field of the invention

[0001] The present invention relates to a process for treating keratin fibers using a composition comprising at least one specific fatty acid, at least one oxygenated terpene compound, and at least one modified polysaccharide. Background of the invention

[0002] External atmospheric agents such as pollution and inclement weather, as well as mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, perming, straightening, and repeated washing, damage and weaken hair. As a result, hair becomes damaged and can eventually become dry, rough, brittle, dull, split, and / or limp, or sensitive to humidity, making hair unruly, often frizzy, and / or difficult to style in humid environments, particularly very humid ones.

[0003] Thus, to remedy these inconveniences, it is common to use hair care products which employ compositions designed to condition the hair properly by providing satisfactory cosmetic properties, including softness to the touch (the hair is no longer rough), good detangling properties leading to ease of combing, good hair discipline which thus has a good shape.

[0004] These hair care products, often based on silicone-based raw materials, can, however, leave a greasy and heavy feel that is not always pleasant for the user. Furthermore, these hair care products have little or no effect on controlling the volume of keratin fibers and / or maintaining the hairstyle and / or the manageability of hair in humid or even very humid environments.

[0005] Furthermore, the formulation of environmentally friendly cosmetic products, that is, products whose design and development take environmental issues into account, is becoming a major concern in order to help address global challenges. It is therefore essential to offer more sustainable compositions that address these environmental issues, particularly by reducing the use of petrochemical-derived compounds.

[0006] Thus, there is a real need to develop a hair treatment process that addresses these drawbacks and is particularly capable of maintaining or even improving the quality of the hair fiber, including softness, detangling, smoothness, manageability, and / or shine, and of permanently limiting frizz formation and / or increased hair volume in humid conditions to facilitate styling in wet environments. Ideally, such a process should not use silicone-based raw materials.

[0007] The applicant has surprisingly discovered that all or part of these objectives can be achieved by the process according to the present invention. Summary of the invention

[0150] The following Cl to C13 compositions were prepared according to the preparation protocol described below:

[0154] The acid is mixed with menthol in a flask. The mixture is heated with stirring at 70°C for 1 hour. After the reaction mixture has cooled to room temperature, compound E is added to the resulting liquid and the mixture is again heated with stirring at 70°C for 20 minutes. After returning to room temperature, the C13 Cl composition is obtained as a slightly viscous, colorless, transparent, oil-like liquid.

[0155] Example 1: Evaluation of hairstyle retention in a humid environment

[0156] Hairstyle hold, i.e. frizz formation and increased hair volume in humid conditions, were evaluated for compositions C3 and C5 according to the evaluation protocol described below.

[0157] Wicks used

[0158] Strands of 2.7 g of Brazilian hair with a length of 27 cm and exhibiting a type IV curl were used.

[0159] Evaluation Protocol

[0160] The strands were washed using a DOP shampoo (0.4 g / g of hair) before application of the compositions to be tested. 81 mg of each of the compositions to be tested were then applied to separate damp strands of hair, previously towel-dried and blotted on absorbent paper. This application was done with the fingers while massaging the hair fiber. The hair strands were then combed, detangled and placed in a glove box at 20% relative humidity at 25°C for 2 hours. The wicks were then placed in an oven at 80% relative humidity at 25°C for 24 hours. Volume and frizz measurements via measurement of the width of the strand at mid-height were carried out at the exit of the oven and compared with the value obtained for a reference strand not having undergone treatment with the composition according to the invention.

[0161] Evaluation Results

[0162] The results of the measurements of the widths of the wicks at mid-height in cm are summarized in the table below:

[0163] [Tables3] Tested compositions Wick width at mid-height (before application of compositions) Wick width at final mid-height (after oven removal) C3 2 3.2 C5 2 3.0 Reference (Untreated wick) 2 4.9

[0164] It is observed that the width values ​​of the strands at mid-height are lower for the strands treated by the process according to the invention than for the reference strand.

[0165] The process according to the invention therefore makes it possible to limit the formation of frizz and the increase in hair volume in humid environments, even in the absence of silicone raw materials.
