Description

COACERVAT CLEANING COMPOSITION

The present disclosure relates to a skin care composition, in particular, a coacervate cleansing composition.

CONTEXT

Current skincare routines typically require multiple steps and multiple products to achieve desired skincare results. Typical skincare routines usually include a skin cleansing step followed by another product to provide various skin benefits such as hydration, anti-aging, or anti-acne. Common skin cleansing products typically rely on surfactants to provide cleansing and do not deposit skincare actives onto the skin.

There is a market need for skin cleansing compositions that can provide increased deposition of skin care actives. As such, consumers are seeking new and improved skin cleansing compositions that can cleanse the skin and also deliver skin care benefits more effectively.

Cationic Polymer :

In the various embodiments, the cosmetic cleansing composition comprises at least one cationic polymer chosen from polymers of natural origin which are polysaccharides, and other natural polymers (i.e. of plant, animal or bacterial origin), synthetic, or of modified natural or synthetic cationic origin.

In some embodiments, the cationic polymer is a naturally occurring polymer. In general, a naturally occurring cationic polymer may be selected from cationic forms and cationic derivatives of polysaccharides isolated from algae, polysaccharides produced by microorganisms, and polysaccharides from higher plants, such as homogeneous polysaccharides.

In some embodiments, the naturally occurring cationic polymer selected from polysaccharides may be selected from polysaccharides that include chitosan, chitin, starches, alginates, celluloses, galactomannans such as guar gums, in particular their cationic derivatives, and combinations thereof. In some embodiments, the at least one naturally occurring cationic polymer selected from polysaccharides may be selected from chitosan, chitosan derivatives, chitin, starch, starch derivatives, cellulose (e.g., but not limited to, ethylcellulose, nitrocellulose, hemicellulose, and hemicellulose derivatives), alginates, including, but not limited to, sodium alginate, and combinations thereof.

In some embodiments, the cationic polymer is a naturally occurring cationic polymer selected from: chitosan, chitosan oligosaccharide, polymeric chitosan having a molecular weight in a range of 1 kDa to about 1000 kDa, chitosan derivatives, chitosan derivatives having enhanced solubility, cyclodextrin, cationic gelatin, cationic dextran, cationic cellulose, polylysine, polyornithine, histone, collagen, chitosan-cysteine, chitosan-thiobutylamidine, chitosan-thioglycolic acid, or combinations thereof. In preferred embodiments, the cationic polymer is selected from chitosan, polylysine, or combinations thereof.

Examples of cationic polymers include polysaccharide-based delivery molecules (e.g., chitosan, cyclodextrin, cationic gelatin, cationic dextran, cationic cellulose), cationic peptides and their derivatives (e.g., polylysine, polyornithine), peptide/protein polymers (e.g., histone, collagen), linear or branched synthetic polymers (e.g., polybrene, polyethyleneimine), natural polymers (e.g., histone, collagen), synthetic dendrimers, thiolated cationic biopolymers (naturally occurring thiomers or naturally occurring dendrimers, e.g., chitosan-cysteine, chitosan-thiobutbutylamidine as well as chitosan-thioglycolic acid).

Examples of naturally occurring cationic polymers include polysaccharide-based delivery molecules (e.g., chitosan, cyclodextrin, cationic gelatin, cationic dextran, cationic cellulose); cationic peptides and their derivatives (e.g., polylysine, polyornithine), peptide/protein polymers (e.g., histone, collagen); thiolated cationic biopolymers (naturally occurring thiomers or naturally occurring dendrimers, e.g., chitosan-cysteine, chitosan-thiobutylamidine, chitosan-thioglycolic acid); or combinations thereof.

In some embodiments, the cosmetic cleansing composition comprises the at least one naturally occurring cationic chitosan selected from chitosan oligosaccharide, chitosan (or polymeric chitosan having a molecular weight (MW) in a range of about 1 kDa to about 1000 kDa), chitosan derivatives, including derivatives having enhanced solubility, or combinations thereof.

In various embodiments, the chitosan has a molecular weight (MW) in a range of about 1 kDa to about 1000 kDa. In some particular embodiments, the chitosan has a MW that is “low” and is in the range of about 1 kDa to about 20 kDa, or about 10 kDa to about 20 kDa, or about 12 kDa to about 18 kDa. In some embodiments, the chitosan has a MW of chitosan =~27 kDa

According to the present invention, the cationic polymer may be selected from polylysines. A single type of polylysines may be used, or two or more different types of polylysines may be used in combination.

Polylysines are the condensation of several lysine amino acids. Polylysine can be a natural homopolymer of L-lysine that can be produced by bacterial fermentation. Polylysines are typically used as a natural preservative in food products. Polylysine is a polyelectrolyte that is soluble in polar solvents such as water.

Polylysine can be, for example, epsilon-polylysine (or designated "ε-polylysine"), which is a condensation of amino groups in the ε position and carboxyl groups of lysines, or alpha-polylysine (or designated "α-polylysine"), which is a condensation of amino groups in the α position and carboxyl groups of lysines. Polylysine is commercially available in different forms, such as poly D-lysine and poly L-lysine. Polylysine is usually a condensate of L-lysines, i.e., poly L-lysine.

• Epsilon-poly-L-lysine de JNC CORPORATION qui est une solution à 25 % d’Epsilon-poly-L-lysine ayant un poids moléculaire moyen en poids d’environ 4.700 en solution aqueuse.

Examples of polylysine include:

• Epsilon-poly-L-lysine from JNC CORPORATION which is a 25% solution of Epsilon-poly-L-lysine having a weight average molecular weight of approximately 4,700 in aqueous solution.

Polylysine can be in the form of organic or inorganic salts. Acid addition salts are, for example, salts of hydrochloric or hydrobromic acid, sulfuric acid, citric acid, succinic acid, tartaric acid, lactic acid, para-toluenesulfonic acid, phosphoric acid, acetic acid; or salts of fatty acids, such as linoleic acid, oleic acid, palmitic acid, stearic acid, behenic acid, 18-methylicosanoic acid. Base addition salts are, for example, a sodium salt, a calcium salt, or a hydroxyalkylamine salt, for example, of N-methylglucamine, aminopropanediol or triethanolamine.

In certain preferred embodiments of the present invention, the polylysine of the present invention is present as a single molecule in the composition, or is not covalently linked to other compounds. In one embodiment of the present invention, the polylysine is not covalently linked to dye compounds. In one embodiment of the present invention, the polylysine is not covalently linked to polyorganosiloxane compounds. The term "polyorganosiloxane" is well known in the art to refer to compounds having an Si-O backbone and organic functional groups attached to the backbone.

In another embodiment of the present invention, the polylysine is in free form. The term "free form" herein indicates that the polylysine is not covalently linked to other compounds.
