Description

Cosmetic composition comprisingCamellia oleiferaoils, liquid fatty esters and solid fatty substances, and cosmetic treatment process

[0001] The present invention relates to a cosmetic composition, in particular a hair composition, comprising particular liquid fatty substances and solid fatty substances, in combination with at least one particular plant oil. The invention also relates to a process for the cosmetic treatment of keratin materials, especially the hair, using said composition.

[0002] Hair may generally be damaged and embrittled by the action of external atmospheric agents such as light and bad weather, and also by mechanical or chemical treatments, such as brushing, combing, dyeing, bleaching, permanent-waving and / or relaxing, or even repeated washing.

[0003] Hair is thus damaged by these various factors and may over time become dry, coarse, brittle or dull, especially in fragile areas, and more particularly at the tips.

[0004] Thus, in order to overcome these drawbacks, it is common practice to make use of hair care compositions intended in particular to condition the hair by giving it satisfactory cosmetic properties. These hair compositions may be, for example, conditioners, masks or serums, and may be in the form of gels, hair lotions or care creams that are more or less thick.

[0005] It is moreover known practice to use compositions of conditioner type, comprising solid fatty esters, camellia oil and cationic surfactants of fatty amine type. However, these compositions may yet be improved, especially as regards the cosmetic properties afforded to the hair, by imparting the hair with a high cosmetic level, especially an improved smooth feel. Also sought are compositions which make it possible to strengthen and / or repair the hair, in particular damaged hair, through a more homogeneous coating of the fiber.

[0006] Moreover, the formulation of environmentally friendly cosmetic products, i.e. products the design and development of which take account of environmental issues, is becoming a major concern for contributing towards meeting global challenges. It is thus essential to propose more sustainable compositions, thereby making it possible to respond to these environmental issues. In this context, it is important to develop novel cosmetic compositions with a good carbon footprint, especially by promoting the use of starting materials that are renewable and / or that have a good naturalness index and / or that are of natural origin and more particularly of plant origin, while reducing the use of compounds of petrochemical origin.

[0007] There is thus a real need to develop cosmetic compositions, especially hair compositions, which are capable of giving hair, especially damaged hair, improved cosmetic properties.

[0008] The aim of the present invention is to propose a composition and a process for treating keratin materials which provide a high level of cosmetic performance, especially for damaged hair.

[0009] This aim is achieved by the present invention, one subject of which is therefore especially a cosmetic composition, in particular a hair composition, comprising:

[0010] - one or moreCamellia oleiferaoils, in a total content of greater than or equal to 0.15% by weight, relative to the total weight of the composition,

[0011] - one or more liquid fatty esters, and

[0012] - one or more solid fatty substances.

[0013] The composition according to the invention makes it possible to provide a very good level of softening (or suppleness) to the keratin fibers: the hair is more supple, less stiff; the head of hair has more movement and bounce, and appears more natural. The softening of the head of hair is reinforced in particular on wet hair: after application of the composition, the hair instantaneously becomes supple, fluid and smooth under water. It appears to be further transformed and treated.

[0014] Also noted are a smooth feel of the hair and also a homogeneity of the coating and of the texture of the keratin fibers, from the root to the tip. The hair appears to be more regular and exhibits a particularly homogeneous coating and an absence of roughness to the touch; the irregularities in the damaged scales are no longer perceptible to the touch; the smooth nature of the head of hair is both visual and tactile; the hair thus appears to be repaired.

[0015] The composition according to the invention thus makes it possible to impart upon the hair advantageous cosmetic properties, such as suppleness, softness, a smooth nature visually and to the touch, ease of disentangling, especially on the most damaged hair.

[0016] In addition, visually, provision of sheen of the head of hair is observed after application of the composition.

[0017] In the present application, and unless otherwise indicated:

[0018] - the term "keratin materials" denotes keratin fibers (in particular the hair, the eyelashes, the eyebrows, the nails) and also the skin of the body and face, including the scalp;

[0019] - the term "at least one" is equivalent to "one or more" and can be replaced therewith; and

[0020] - the limits of a range of values are included within that range, especially in the expressions "of between" and "ranging from ... to ...", these expressions being interchangeable.Camellia oleifera oil

[0021] The composition also comprises one or more oils of camellia belonging to the speciesCamellia oleifera.

[0022] Said oil(s) may be extracted from all or part of the plant, in particular from the stem, the leaves, the buds, the roots, the flowers, the petals and / or the seeds; advantageously, the oil is extracted from the seeds.

[0023] The extraction may be performed in any way known to a person skilled in the art; advantageously, it is performed by pressing, in particular by cold pressing, of the plant or plant part(s) under consideration. After extraction, the oil may be purified.

[0024] Preferably, use is made of aCamellia oleiferaseed oil, obtained in particular by pressingCamellia oleiferaseeds.

[0025] In the context of the invention, use may in particular be made of the oil with the INCI name "CAMELLIA OLEIFERA SEED OIL".

[0026] The composition according to the invention comprises theCamellia oleiferaoil(s) in a total amount of greater than or equal to 0.15% by weight, relative to the total weight of the composition.

[0027] In particular, the composition according to the invention may comprise theCamellia oleiferaseed oil(s) in a total amount of greater than or equal to 0.15% by weight, relative to the total weight of the composition.

[0028] Preferably, the composition according to the invention comprises theCamellia oleiferaoil(s) in a total amount ranging from 0.15% to 5% by weight relative to the total weight of the composition, especially from 0.17% to 2% by weight, even better still from 0.18% to 1.5% by weight, preferentially from 0.20% to 1% by weight, relative to the total weight of the composition.

[0029] Preferably, the composition according to the invention comprises theCamellia oleiferaseed oil(s) in a total amount ranging from 0.15% to 5% by weight relative to the total weight of the composition, especially from 0.17% to 2% by weight, even better still from 0.18% to 1.5% by weight, preferentially from 0.20% to 1% by weight, relative to the total weight of the composition.Liquid fatty esters

[0269] The present invention is illustrated in greater detail in the following examples.Example 1

[0270] The cosmetic composition according to the invention A and comparative cosmetic composition A' are prepared from the ingredients shown in the table below, the amounts of which are expressed as percentage by weight of active material (% g AM).

[0271] A (invention)A' (comparative)Stearamidopropyl dimethylamine33Isopropyl myristate1.51.5Camellia oleiferaoil(INCI: CAMELLIA OLEIFERA SEED OIL)0.20.1Cetyl esters(INCI: CETYL ESTERS)22Cetearyl alcohol77Glycerol22Tartaric acid0.70.7PreservativesqsQsWaterqs 100qs 100Sensory evaluation

[0272] The locks of sensitized (AS20) hair of Caucasian type are cleansed by applying a standard shampoo (DOP chamomile), in a proportion of 0.3 g per gram of lock. The locks are then rinsed with water for 15 seconds (flow rate: 300 l / h – temperature 35°C).

[0273] Composition A or A' is applied to the locks of still-wet hair, in a proportion of 0.45 g per gram of lock. After a waiting time of 5 minutes, the lock is rinsed with water for 10 seconds (flow rate: 300 l / h – temperature 35°C).

[0274] The suppleness of the locks of hair treated with compositions A or A' is evaluated blind on wet hair, by 5 trained evaluators, and scored on a scale ranging from 0 [not] to 10 [very] in increments of 0.5.

[0275] The suppleness is evaluated as follows: the evaluator takes handfuls of the hair and tries to fold it. The more easily the hair can be folded or bent, the more pliable it is, the better the suppleness.

[0276] The following results are obtained:

[0277] Performance criterionComposition A(invention)Composition A'(comparative)SupplenessScores: 7 / 7 / 6 / 7 / 8Mean: 7 ± 0.7Scores: 5 / 5 / 5 / 5 / 5Mean: 5 ± 0

[0278] It is found that, for all the evaluators, composition A according to the invention provides cosmetic performance qualities in terms of suppleness which are superior to those provided by composition A'. These results are statistically significant.Measurement of the reptation force

[0279] Locks of sensitized (AS20) hair of Caucasian type are cleansed by applying a standard shampoo (DOP chamomile), in a proportion of 0.3 g per gram of lock. The locks are then rinsed with water for 15 seconds (flow rate: 300 l / h – temperature 35°C).

[0280] Composition A or A' is applied to the locks of still-wet hair, in a proportion of 0.4 g per gram of lock. After a leave-on time of 5 minutes, the lock is rinsed with water for 10 seconds (flow rate: 300 l / h – temperature 35°C).

[0281] The suppleness on wet hair is evaluated by measuring the reptation force of the lock, moving at a constant speed (500 mm / min), over a path consisting of rollers that can rotate on themselves without friction. This method is presented in particular in the publicationJ. Cosmet. Sci.,60, 135–141 (2009). 6 samples per condition are evaluated.

[0282] The lower the force required to pass the lock through the rollers, the more the lock is said to be "supple".

[0283] The following results are obtained (mean over 6 values):

[0284] Composition A(invention)Composition A'(comparative)Work (rotational W) (mJ)18.4 ± 3.0226.5 ± 4.12

[0285] By comparing condition A with condition A', it is found that the p-value is 0.003; the results are therefore statistically very significant.

[0286] Composition A according to the invention thus affords a cosmetic quality benefit, with in particular significantly better softening of the wet head of hair. The hair thus appears to be further transformed and better treated.Example 2

[0287] The compositions according to the invention B and C are prepared from the ingredients shown in the table below, the amounts of which are expressed as percentage by weight of active material (% g AM).

[0289] The compositions thus obtained can be used as rinse-off hair masks.

[0290] It is found that they confer good cosmetic performance qualities to the hair, especially in terms of smooth feel, suppleness and softness. The hair appears to be transformed, better treated and less dry than with a conventional mask, and thus appears to be repaired.
