Description

Composition for cleaning keratin materials

The present invention relates to cleansing and/or exfoliating compositions useful for personal skin care.

The skin is a protective barrier for the human body. It protects the interior of the body from physical damage (e.g., wounds) and biological damage (e.g., bacteria, viruses, or fungi). Human skin comprises dermis and epidermis. The epidermis is the uppermost layer of the skin, and its surface layer is called stratum corneum.

The stratum corneum or horny layer (horny layer) generally consists of 10 to 30 layers of dead cells. These cells are continuously replaced by new cells below. It is estimated that about 1 month is required for the stratum corneum to be completely replaced with new cells in adult human skin. The replacement time increased with age until approximately 120-150 days. The longer it takes to replace dead cells, the more layers of dead cells accumulate.

It is therefore desirable to remove an excessive layer of dead skin cells from the skin surface to provide a shiny skin with a youthful appearance. The process of removing dead skin cells from the surface of the skin is called exfoliation.

On the other hand, cleansing the skin is an essential step for caring for keratin materials, in particular facial skin. It must be as efficient as possible, since greasy residues, such as dust, excess sebum and residues of cosmetic and make-up products used daily, can lead to an unpleasant greasy appearance. Several types of skin cleansing products are known, such as flushable anhydrous cleansing oils and gels, foaming creams, lotions and gels, and non-foaming compositions.

Currently, human skin is cleaned and/or exfoliated in many different ways, such as cleaning products that are mechanically rubbed with or without the use of any kind of hard particles. These particles are also known as sanding beads. Classic cleansing or exfoliating compositions currently on the market can be classified as cleansing compositions with or without abrasive beads. The addition of abrasive beads is known to provide stronger and better cleaning of the skin, particularly pore cleaning. These beads may be hydrocarbon wax beads, particles such as silica, and Polyethylene (PE) beads.

However, each of these beads has some associated problems. In fact:

the hydrocarbon wax beads are relatively large in size, in particular 300 to 2000 μm, and tend to be soft in cleansing or exfoliating formulations, which is undesirable;

particles such as silica tend to be too small in size (i.e. nanoparticles) during production, which causes dusting problems; and

PE beads break during application, which is not suitable for cleaning purposes.

In addition, known scrub beads tend to be rough after application to the skin. This is even worse for consumers of sensitive skin types.

In other cases, sodium salts are used as abrasive beads in cleaning and exfoliating compositions. However, due to the high amount of salt present, it is inevitable to use surfactants such as SLES (sodium lauryl sulfate) to maintain the foaming properties of the composition. Surfactants of this type are known for their strong cleaning power and for their irritancy (harshness) to the skin, in particular to sensitive skin.

Therefore, there is a need to formulate compositions for the care of keratin materials that have excellent cleansing and/or exfoliating properties, while maintaining a mild and light feel after application.

There remains a need for new compositions having the above properties and having excellent foaming properties.

Furthermore, there is a need for cleansing and/or exfoliating compositions having the above properties while being stable over time.

Applicants have now found that by combining specific surfactants with high amounts of salt, compositions can be formulated having the desired properties as described above.

The present invention therefore relates to a composition for caring for keratin materials (also referred to as "composition of the invention") comprising, in an aqueous phase:

a) at least one C₂-C₆A polyol;

b) at least one glycinate surfactant; and

c) at least 5% by weight of at least one water-soluble inorganic salt, relative to the total amount of the composition.

The composition of the present invention can provide gentle massaging and cleansing of the skin without any harsh feeling.

The compositions of the present invention also provide good lathering during application.

It can be used daily as a facial or body cleanser and/or an exfoliating composition. In addition, the compositions of the present invention are stable over time. By stable is meant that the composition does not undergo any significant change in its structure or properties for at least one month, especially for at least two months, after its manufacture.

According to one embodiment, the present invention provides a composition for cleansing and/or exfoliating keratin materials comprising ingredients of natural origin. Preferably, all the ingredients of the composition of the invention are of natural origin.

The compositions of the present invention are rinse-off products. Thus, such compositions are applied to the skin (i.e., the face and/or body) and then rinsed.

Other objects and features, aspects and advantages of the present invention will become more apparent upon reading the following description and examples.

In the following and unless otherwise indicated, the limits of the numerical ranges are included within this range, in particular in the expressions "between …" and ". multidot..

Furthermore, the expression "at least one" as used in the present specification is equivalent to the expression "one or more".

Throughout this application, the term "comprising" is to be interpreted as covering all specifically mentioned elements as well as optional, additional, unspecified elements. As used herein, the use of the term "comprising" also discloses embodiments in which no element other than the specifically mentioned element is present (i.e., "consisting of …").

Thus, the composition of the invention comprises, in the aqueous phase:

a) at least one C₂-C₆A polyol;

b) at least one glycinate surfactant; and

₂ ₆One or more C-C polyols

The polyols according to the invention may preferably be selected from linear or branched, saturated or unsaturated C's having at least two hydroxyl groups₂-C₆A polyol, a dialkylene polyol having at least two hydroxyl groups, or a mixture thereof.

As polyols which may be used in the composition of the present invention, mention may be made of glycerol, propylene glycol, butylene glycol, sorbitol, hexylene glycol or mixtures thereof.

In particular, the composition of the invention comprises from 10% to 70% by weight, more preferably from 20% to 60% by weight of C, relative to the total weight of the composition₂-C₆A polyol.

One or more glycinate surfactants

The compositions of the present invention comprise at least one glycinate surfactant.

In one embodiment, the glycinate surfactant is derived from a carboxylic acid salt of glycine, wherein the amine group located on the α -carbon or β -carbon of the glycinate is replaced by a C₈To C₂₂Acylation of the fatty acid derivative.

These carboxylic acid salts of glycine may be formed by conventional means, such as by neutralizing glycine with a base.

The amine group located on the alpha-carbon or beta-carbon of the neutralized glycine is acylated with a fatty acid halide (acid halide) in the presence of a base by the well-known Schotten-Baumann reaction to produce an amide, thereby forming the desired surfactant reaction product, a glycinate salt surfactant.

Suitable acid halides for acylation of the amino acid carboxylate include acid chloride, bromide, fluoride, and iodide.

The acid halide may be obtained by reacting a saturated or unsaturated, linear or branched C₈To C₂₂Fatty acids are prepared by reaction with thionyl halides (bromine, chlorine, fluorine and iodine). Representative acid halides include, but are not limited to, acid chlorides selected from the group consisting of decanoyl chloride, dodecanoyl chloride (lauroyl chloride), cocoyl chloride (coconut oil derived fatty acid chloride), tetradecanoyl chloride (myristoyl chloride), hexadecanoyl chloride (palmitoyl chloride), octadecanoyl chloride (stearoyl chloride), 9-octadecenoyl chloride (oleanoyl chloride), eicosanoyl chloride (arachidoyl chloride), docosanoyl chloride (behenoyl chloride), and any mixtures thereof.

Other acid halides include bromides, fluorides, and iodides of the above fatty acids. Methods for preparing acid halides and alternative methods for acylating amino acids are set forth in U.S. patent application publication 2008/0200704, published on 21/8/2008, which is incorporated herein by reference.

In one embodiment, the glycinate surfactant is represented by formula (I):

formula (I)

Wherein:

z represents a saturated or unsaturated, linear or branched hydrocarbon radical having from 8 to 22 carbon atoms,

x and Y are hydrogen radicals,

n is a number of 0, and n is,

m is a salt-forming cation, such as sodium, potassium, ammonium, or triethanolamine, where COO is a counter anion.

Examples of glycinate surfactants are palmitoyl glycinate, sodium lauroyl glycinate, sodium cocoyl glycinate, sodium myristoyl glycinate, potassium lauroyl glycinate, potassium cocoyl glycinate and mixtures thereof.

In formula (I) preferably:

z represents a saturated straight chain C₈To C₂₂An alkyl group, a carboxyl group,

x and Y are hydrogen radicals,

n is a number of 0, and n is,

Mention may be made of commercially available amino acid surfactants, for example Amilite from Ajinomoto^®Sodium N-cocoyl glycinate sold under the name GCS-12K, potassium cocoyl glycinate sold under the name Eversoft YCK-100K by Sino Lion corporation or Amilite sold under the name Ajinomoto corporation^®GCK-12K is a product sold under the name GCK-12K and mixtures thereof.

According to a preferred embodiment, the glycinate salt surfactant is sodium N-cocoyl glycinate.

According to the invention, the glycinate surfactant is present in an amount ranging from 1% to 30% by weight, preferably from 2% to 20% by weight and more preferably from 3% to 15% by weight relative to the total weight of the composition.

One or more water-soluble inorganic salts

According to one embodiment, the composition of the invention comprises at least 5% by weight of at least one water-soluble inorganic salt, relative to the total weight of the composition.

By "water soluble" is meant that the inorganic salt has a solubility in water of at least 100 g/L at room temperature, preferably at least 200 g/L at room temperature.

According to one embodiment, the inorganic salts suitable for use in the compositions of the present invention have a structure selected from Na⁺、K⁺、Li⁺、Ca²⁺、Mg²⁺、Cu²⁺Or Zn²⁺And a cation selected from the group consisting of halide, HCO₃ ^-Or HPO₄ ^-The anion of (4).

Preferably, a halogen ion is used.

The cation is preferably monovalent or divalent. Preferred cations are selected from Na, Ca, Li, K, Mg, Cu and Zn.

Preferred salts are selected from sodium chloride, potassium chloride, lithium chloride, ammonium chloride or mixtures thereof.

These salts are known for their good solubility in water and are therefore very often used in cosmetic formulations to adjust the pH of the formulation, to thicken micellar systems or to help stabilize emulsions.

Surprisingly, the present inventors have found that the combination of ingredients in the composition of the present invention enables the inorganic water soluble salt to be present in the composition in particulate form, rather than being dissolved, thus providing a frosting function to the skin during application. Thus, the compositions of the present invention provide excellent and mild exfoliating effects to the skin.

The inorganic salt may be present in the composition in a content of more than 5% by weight, preferably from 6% to 40% by weight, preferably from 7% to 35% by weight, more preferably from 10% to 30% by weight, relative to the total weight of the composition.

It is known to the person skilled in the art that salts, in particular water-soluble inorganic salts, have an influence on the foaming of compositions present on the market. Which in particular hampers foam generation or defoams in the cosmetic composition. To overcome this problem, conventional techniques use surfactants such as SLES in combination with low amounts of salts.

However, this type of composition does not provide an exfoliating effect because the salt is not present in the composition in particulate form. Furthermore, it does not provide a mild and gentle cleansing of the skin.

Surprisingly, the present invention makes it possible to formulate compositions for the cleansing and/or exfoliation of keratin materials comprising a high amount of salt in combination with glycinate surfactants and providing excellent lathering properties.

According to a preferred embodiment, said at least one C₂-C₆The weight ratio of the polyol to the at least one water-soluble inorganic salt is greater than or equal to 1, preferably from 1 to 10, more preferably from 1.5 to 5. According to this preferred embodiment, the at least one C is due to the fact that the salt is in particle form and provides the skin with the desired abrasive feel₂-C₆The ratio of the polyol and the at least one water-soluble inorganic salt may ensure excellent cleansing and exfoliating effects.
