Abstract
Description
Title of the invention: Cosmetic composition comprising fatty amines, quaternary ammonium diesters, phosphated starches and fatty esters; and cosmetic processing method
[0001] The present invention relates to a cosmetic composition, particularly for hair, comprising a combination of at least two different cationic surfactants, phosphated starch, and a specific fatty ester. The invention also relates to a cosmetic treatment process for keratinous materials, particularly hair, using said composition.
[0002] Hair can generally be damaged and weakened by the action of external atmospheric agents such as light and inclement weather, as well as by mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, perming and / or straightening, or even repeated washing. Hair thus becomes damaged by these various factors and can eventually become dry, rough, brittle or dull, particularly in fragile areas, and especially at the ends.
[0003] Thus, to remedy these drawbacks, it is common to use hair care compositions specifically designed to condition the hair by providing it with satisfactory cosmetic properties. These hair care compositions may be, for example, conditioners, masks, or serums, and may be in the form of gels, hair lotions, and conditioning creams of varying thicknesses.
[0004] It is also known to use conditioner-type compositions, comprising cationic surfactants, solid and liquid fats, and phosphated starches.
[0005] However, these compositions can still be improved, particularly with regard to the cosmetic properties provided to the hair; in particular, compositions providing a high level of cosmeticity to the hair are sought, including a smooth feel, good suppleness and improved coating, as well as a notable strengthening of the fiber, particularly interesting in the case of damaged hair.
[0006] 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 meet global challenges. It is therefore essential to offer more sustainable compositions that address these environmental challenges. In this In this context, it is important to develop new cosmetic compositions with a good carbon footprint, in particular by promoting the use of renewable raw materials and / or with a good naturalness index and / or of natural origin, and more particularly of plant origin, while reducing the use of petrochemical compounds.
[0007] There is therefore a real need to develop cosmetic compositions, particularly for hair, which are capable of giving hair, especially damaged hair, improved cosmetic properties, in particular leading to an improvement in perceived performance in terms of fiber repair / nourishment.
[0008] The aim of the present invention is to propose a composition and a process for treating keratinous materials which provide a high level of cosmetic performance, particularly for damaged hair.
[0009] This objective is achieved with the present invention, which therefore relates in particular to a cosmetic composition, especially for hair, comprising:
[0010] - one or more fatty amines,
[0011] - one or more quaternary ammonium diesters,
[0012] - one or more phosphated starches, and
[0013] - one or more fatty acid and fatty alcohol esters, preferably solid,
[0014] in which:
[0015] the weight ratio (R') between the total content of fatty acid and fatty alcohol esters on the one hand, and the total content of fatty amines on the other hand, is greater than or equal to 1; and / or
[0016] the weight ratio (R”) between the total content of fatty acid and fatty alcohol esters on the one hand, and the total content of quaternary ammonium diesters on the other hand, is greater than or equal to 1.
[0017] It has been observed that the composition according to the invention therefore makes it possible to provide advantageous cosmetic properties to hair, in particular damaged hair, such as suppleness, softness, a smooth visual and tactile character, ease of detangling, particularly on the most damaged hair.
[0018] The composition according to the invention provides a very good level of suppleness to the keratin fibers: the hair is more supple, less stiff; the hair has more movement, bounce, and appears more natural. After application of the composition, the hair instantly becomes supple and fluid; it appears more transformed, treated, and nourished.
[0019] A smooth feel is also observed, as well as a homogeneity of the coating and texture of the keratin fibers, from root to tip, which results in a more homogeneous feel. The hair appears more regular and has a particularly homogeneous coating, with no roughness to the touch. The irregularities of the damaged scales are no longer perceptible to the touch; the hair therefore appears, in effect, to be repaired and strengthened.
[0020] Moreover, the composition has good qualities of use, in particular an ease of distribution from root to tip.
[0021] In this application, and unless otherwise indicated:
[0022] - by "keratinous materials" means keratinous fibers (in particular the hair, eyelashes, eyebrows, nails) as well as the skin of the body and face, including the scalp;
[0023] - the term "at least one" is equivalent to "one or more" and can be substituted; and

[0244] Cosmetic compositions according to invention A and B and comparative A' and B' are prepared from the ingredients indicated in the table below, the quantities of which are expressed as a percentage by weight of active material (g% MA).
[0245] [Tables 1] A (inv) A' (comp) B (inv) B' (comp) Stearamidopropyl dimethylamine (i) 1 1.25 1.5 1.5 Dipalmitoylethyl hydroxyethylmonium methosulfate (ii) 1.5 1.5 1.005 1.251 Cetyl esters 1.25 1 1.25 1.25 Distarch phosphate 1.5 1.5 1.5 1.5 Cetearyl alcohol 5.7 5.7 4.5 4.5 Sunflower oil 0.9 0.9 0.9 0.9 Tartaric acid 0.4 0.4 0.4 0.4 Preservatives, fragrance Qs Qs Qs Qs Water Qsp 100 Qsp 100 Qsp 100 Qsp 100 Cetyl ester / (i) ratio 7.25 0.80 0.83 0.83 Cetyl ester / (H) ratio 0.83 0.67 1.244 0.999
[0246] Compositions are obtained that can be used for the care and conditioning of hair, for example as a rinse-out conditioner.
[0247] The cosmetic performance provided by compositions A and B according to the invention is evaluated in comparison with that provided respectively by the comparative compositions A' and B'.
[0248] Protocol:
[0249] Strands of Caucasian hair, previously sensitized by a bleaching treatment (SA20), are cleaned by applying a standard shampoo (DOP chamomile) at a rate of 0.3 g per gram of strand. The strands are then rinsed with water for 15 seconds (flow rate: 300 L / h - temperature 35°C). The composition to be tested is applied to the still-wet hair strands at a rate of 0.45 g per gram of strand. After a waiting period of 5 minutes, the strand is rinsed with water for 10 seconds (flow rate: 300 L / h - temperature 35°C). After wringing, the strands are dried with a hairdryer and then evaluated.
[0250] The cosmetic performance of compositions A and A' is evaluated based on the criteria of smoothness to the touch. The cosmetic performance of compositions B and B' is evaluated based on the criterion of coating homogeneity.
[0251] Performance is assessed blindly by 5 trained evaluators, who assign a score from 0 (no performance) to 5 (very high performance), in increments of 0.5, on the criterion tested.
[0252] Evaluation of smoothness to the touch: the evaluator takes a strand of hair at the root and runs it between their fingers along its entire length to the tips. The more uniform and homogeneous the hair is from root to tip, the fewer rough edges it has, the less it catches the fingers, and the better its smoothness to the touch.
[0253] Coating assessment: The assessor takes the strand of hair in their hand, starts at the root, and slides it to the tips. The more even the deposit is felt along the fiber, the better the coating homogeneity.
[0254] The following results are obtained:
[0255] [Tables2] Composition A Composition A' Smooth to the touch Scores: 4 / 4 / 4 / 4 / 4 Average: 4 Standard deviation: 0 Scores: 3 / 2 / 3 / 3 / 3 Average: 2.8 Standard deviation: 0.4
[0256] [Tables3] Composition B Composition B' Coating Notes: 4 / 3 / 3 / 4 / 3 Average: 3.4 Standard deviation: 0.5 Notes: 2 / 1 / 2 / 3 / 2 Average: 2.0 Standard deviation: 0.7
[0257] It is observed that the compositions according to the invention provide better cosmetic properties on dry hair: the hair appears smoother and more even (sign of a better level of treatment); the coating is of better quality, one perceives a sheathed and regular fiber from root to tip.
