Description

[Technical field]

[0001] The present invention relates to a composition comprising at least one cationic polymer and at least one basic amino acid, and to a cosmetic method using the composition. [Background technology]

[0002] Environmentally compatible cosmetic formulations, which are designed and developed with environmental issues in mind, have become a major goal to meet global challenges.

[0003] It is therefore essential to propose more sustainable compositions, preparation methods and ingredients to address these environmental issues.

[0004] In this context, it is important to develop new cosmetic compositions that have a better carbon footprint, in particular by promoting the use of renewable raw materials and / or materials with a good natural index and / or materials of natural origin, more particularly materials of plant origin, while reducing the use of compounds of petrochemical origin.

[0005] Polyion complexes formed from anionic polymers and cationic polymers are already known.

[0006] For example, WO2021 / 125069 discloses a composition useful for cosmetic treatment, comprising at least one cationic polymer, at least one anionic polymer, and at least one polyion complex particle comprising a non-polymeric acid having two or more pKa values. WO2021 / 125069 also discloses that the composition disclosed herein may include an oil and may be in the form of an emulsion. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] After extensive investigation, the inventors have discovered that it is possible to provide a stable, odorless composition that comprises at least one oil and water, and that may contain at least one environmentally compatible ingredient.

[0028] The composition according to the invention comprises (a-1) at least one cationic polymer; (a-2) at least one monovalent non-polymeric acid or a salt thereof; (a-3) water, (b-1) at least one oil, and (b-2) at least one basic amino acid Includes.

[0029] The compositions of the present invention are stable and odorless.

[0030] The composition of the present invention is stable and therefore does not undergo phase separation over a long period of time and maintains a uniform appearance, therefore the composition of the present invention can be stored for a long period of time.

[0031] The compositions of the present invention are odorless, although they contain at least one oil that may cause rancidity, and are therefore useful for cosmetic applications.

[0032] When the (a-1) cationic polymer is obtained from a natural resource, the (a-1) cationic polymer can be an environmentally compatible component. For example, the (a-1) cationic polymer can be selected from environmentally compatible chitosan. Therefore, the composition of the present invention can include an environmentally compatible component.

[0033] In addition, components (a-2), (b-1) and (b-2) can originate from renewable and / or biodegradable materials, such as plants, and therefore the composition of the present invention can be environmentally compatible.

[0034] The present invention will now be described in more detail.

[0035] [Composition] The composition of the present invention comprises (a-1) at least one cationic polymer; (a-2) at least one monovalent non-polymeric acid or a salt thereof; (a-3) water, (b-1) at least one oil, and (b-2) at least one basic amino acid Includes.

[0036] In the composition of the present invention, at least (a-1) the cationic polymer and (b-2) the basic amino acid can form at least one type of complex.

[0037] (a-1) Cationic polymer amino (-NH 2 ) or ammonium (-NH 3 + A moiety that can have a positive charge and / or has a positive charge, such as a carboxylate (-COOH) group, can ionic interact with the carboxylic acid (-COOH) or carboxylate (-COO-) group of the basic amino acid (b-2) to form a complex. The complex contains at least one hydrophobic moiety derived from the basic moiety of the basic amino acid (b-2). Thus, the cationic polymer (a-1) can be hydrophobized by the basic amino acid (b-2) by forming a complex.

[0038] The complex of (a-1) cationic polymer and (b-2) basic amino acid can be present at the interface between (b-1) oil-containing fatty phase and (a-3) water-containing aqueous phase. The fatty phase can be stabilized by said complex. Thus, the aggregation of the fatty phase can be prevented. This stabilization can be brought about without using any conventional surfactant. In one embodiment, the composition of the present invention can be in the form of an O / W emulsion, which can also resemble a so-called Pickering emulsion.

[0039] According to the present invention, the (b-1) oil may be surrounded by a plurality of complexes of the (a-1) cationic polymer and the (b-2) basic amino acid. In other words, the (b-1) oil may be coated with the above complex. The complex may be in the form of particles. Therefore, the (b-1) oil may be coated with particles containing the above complex.

[0040] The (b-1) oil surrounded by the above complex of (a-1) cationic polymer and (b-2) basic amino acid cannot directly contact keratinous materials such as skin. Therefore, even if the (b-1) oil has a sticky or oily feel when used, the composition of the present invention is not expected to have a sticky or oily feel when used.

[0041] (cationic polymer) The composition of the present invention comprises (a-1) at least one cationic polymer. A single type of cationic polymer may be used, or two or more different types of cationic polymers may be used in combination.

[0043] It may be preferable that the molecular weight of the (a-1) cationic polymer is 1,000 or more, preferably 2,000 or more, more preferably 3,000 or more, and even more preferably 4,000 or more.

[0044] It may be particularly preferred that the (a-1) cationic polymer has a molecular weight of greater than 20,000.

The term (primary) "amino group" as used herein means -NH 2 means a group.

[0047] The (a-1) cationic polymer may be a homopolymer or a copolymer. The term "copolymer" is understood to mean both copolymers obtained from two types of monomers and those obtained from more than two types of monomers, for example terpolymers resulting from three types of monomers.

Other examples of suitable cationic polymers include, but are not limited to, cationic proteins and cationic protein hydrolysates, polyalkyleneimines, such as polyethyleneimines, polymers comprising units selected from vinylpyridine units and vinylpyridinium units, condensates of polyamines with epichlorohydrin, quaternary polyureylenes, and chitin derivatives.

[0087] According to one embodiment of the present invention, the (a-1) cationic polymer is selected from cellulose ether derivatives containing quaternary ammonium groups, such as the product sold under the name "JR 400" by UNION CARBIDE CORPORATION, cationic cyclopolymers, such as the homopolymers and copolymers of dimethyldiallylammonium chloride sold under the names MERQUAT® 100, MERQUAT® 550 and MERQUAT® S by CALGON, guar gum modified with 2,3-epoxypropyltrimethylammonium salt, and quaternary polymers of vinylpyrrolidone and vinylimidazole.

[0088] (13) Polyamines As (a-1) cationic polymer, it is also possible to use (co)polyamines, which may be homopolymers or copolymers, having a plurality of amino groups. The amino groups may be primary, secondary, tertiary or quaternary amino groups. The amino groups may be present in the polymer backbone of the (co)polyamine or, if present, in pendant groups.

[0089] Examples of (co)polyamines include chitosan, (co)polyallylamine, (co)polyvinylamine, (co)polyaniline, (co)polyvinylimidazole, (co)polydimethylaminoethylene methacrylate, (co)polyvinylpyridine such as (co)poly-1-methyl-2-vinylpyridine, (co)polyimines such as (co)polyethylenimine, (co)polypyridines such as (co)poly(quaternary pyridine), (co)polybiguanides such as (co)polyaminopropyl biguanide, (co)polylysine, (co)polyornithine, (co)polyarginine, (co)polyhistidine, aminodextran, aminocellulose, amino(co)polyvinyl acetal, and salts thereof.

For example, polylysine can be ε-poly-L-lysine, which is typically used as a natural preservative in food. Polylysine is a polyelectrolyte that is soluble in polar solvents, such as water, propylene glycol and glycerol. Polylysine is commercially available in various forms, such as poly-D-lysine and poly-L-lysine. Poly-L-lysine is preferred. Polylysine may be in the form of a salt and / or a solution.

[0091] (14) Cationic polyamino acids (a-1) As the cationic polymer, it may be possible to use cationic polyamino acids, which may be cationic homopolymers or copolymers having multiple amino and carboxyl groups. The amino groups may be primary, secondary, tertiary or quaternary amino groups. The amino groups may be present in the polymer backbone of the cationic polyamino acid or in pendant groups, if present.
