Description

[Technical field]

[0001] The present invention relates to a composition comprising at least one glycolipid, at least one taurine surfactant, and at least one amino acid surfactant, preferably a cosmetic composition comprising the same, more preferably a rinse-off cosmetic composition comprising the same. [Background technology]

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

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

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

[0005] Biosurfactants such as glycolipids, including rhamnolipids, are naturally occurring materials known to have unique biological activities, such as anti-inflammatory efficacy, anti-allergic efficacy, antibacterial efficacy, etc. For example, glycolipids are known to have anti-inflammatory efficacy and are potentially of use on keratinous materials such as skin.

[0006] For example, JP2015-507626A discloses a composition comprising water, at least one biosurfactant, and at least one fatty acid, in which the total fraction of all surfactants in the composition is 1-30% by mass, and the fraction of fatty acids is 0.1-20% by mass based on the total of the fatty acids and the surfactants.

[0007] However, although glycolipids have some unique biological activities, there is a problem in that compositions containing glycolipids may become less stable when the temperature is changed.

[0008] Thus, there is a need to provide compositions comprising glycolipids that exhibit improved stability against temperature changes. [Prior art documents] [Patent documents]

Typically, amino acid surfactant is an anionic surfactant that contains at least one amino moiety and at least one carboxylic acid moiety in the form of carboxylate. Amino acid surfactant may have two or more amino moieties and / or two or more carboxylic acid moieties in the form of carboxylate. Amino acid surfactant may also be called amino acid-based surfactant.

[0113] (c) The amino acid surfactant is different from the (b) taurine surfactant herein.

[0114] (c) amino acid surfactant can be preferably selected from amino acid derivatives. More preferably, amino acid derivatives can be selected from salts of amino acids and N-acylated amino acids, such as alkali metal salts and alkaline earth metal salts of amino acids and N-acylated amino acids, such as sodium salts, potassium salts, magnesium salts and calcium salts of amino acids and N-acylated amino acids. Therefore, (c) amino acid surfactant is preferably N-acyl amino acid surfactant.

[0117] The carboxylates of these amino acids can be formed by conventional means such as neutralizing the respective amino acids with a base. The amine group located on the α- or β-carbon of the neutralized amino acid is acylated with a fatty acid halide (acyl halide) in the presence of a base via the well-known Schotten-Baumann reaction to generate an amide, thus forming the desired surfactant reaction product, i.e., the amino acid surfactant. Suitable acyl halides for acylation of the amino acid carboxylates include acyl chlorides, acyl bromides, acyl fluorides and acyl iodides. The acyl halides can be saturated or unsaturated, linear or branched, C8-C 22 They can be prepared by reacting fatty acids with thionyl halides (bromides, chlorides, fluorides and iodides). Representative acyl halides include, but are not limited to, acyl chlorides selected from decanoyl chloride, dodecanoyl chloride (lauroyl chloride), cocoyl chloride (fatty acid chloride derived from coconut oil), tetradecanoyl chloride (myristoyl chloride), hexadecanoyl chloride (palmitoyl chloride), octadecanoyl chloride (stearoyl chloride), 9-octadecenoyl chloride (oleoyl chloride), eicosanoyl chloride (arachidoyl chloride), docosanoyl chloride (behenoyl chloride), and any mixtures thereof. Other acyl halides include bromides, fluorides and iodides of the aforementioned fatty acids.

[0210] The present invention will now be described in more detail by examples, which should not be construed as limiting the scope of the present invention.

[0211] (Examples 1 to 5 and Comparative Examples 1 to 3) The homogeneous solution compositions according to Examples 1-5 and Comparative Examples 1-3 were prepared by mixing the components listed in Tables 1 and 2 using a magnetic stirrer. All values ​​for the amounts of components shown in the tables are based on the "mass %" of the active ingredient. As the glycolipid, a rhamnolipid surfactant obtained from EVONIK (product name: RHEANCE (registered trademark) One) was used.

[0212] [evaluation] The stability of each of the compositions according to Examples 1 to 5 and Comparative Examples 1 to 3 was evaluated as follows.

[0213] (+20℃ / -20℃ cycle) Each composition was placed in a cylindrical transparent sample vial (SV-30) and stored for 5 days in a cycle incubator in which the temperature was controlled within a cycle of +20° C. and −20° C. The appearance of the composition was observed with the naked eye and evaluated based on the following criteria. Good: No precipitation was observed and the original appearance was maintained. Poor: White precipitate particles were observed at the bottom of the sample vial. Very poor: A white deposit was observed at the bottom of the sample vial.

[0214] The temperature cycle consisted of the following steps: (a) keeping the sample at +20°C for 6 hours; (b) cooling the samples to −20° C. for 6 hours; (c) keeping the samples at −20° C. for 6 hours; (d) heating the sample to +20°C for 6 hours; (e) Repeat step (a) above.

[0215] (-5℃, 4℃, or RT) Immediately after preparation of each composition, the composition was placed in a cylindrical transparent sample vial (SV-30) and stored in an incubator at -5°C, 4°C or room temperature for 7 days. The appearance of the composition was observed with the naked eye and evaluated based on the following criteria. Good: No precipitation was observed and the original appearance was maintained. Poor: White precipitate particles were observed at the bottom of the sample vial. Very poor: A white deposit was observed at the bottom of the sample vial.

[0216] The results are summarized in Tables 1 and 2 below.

[0217] [Table 2]

[0218] [Table 3]

[0219] As can be seen from Tables 1 and 2, the compositions according to Examples 1 to 5 containing specific amounts and combinations of (a) glycolipid and (b) taurine surfactant components, and (c) amino acid surfactant, exhibited improved stability against temperature changes and from low to RT.

[0220] On the other hand, the compositions according to Comparative Examples 1 to 3, which did not contain a sufficient amount of (b) taurine surfactant, failed to show improved stability.

[0221] Accordingly, it can be said that the compositions according to the invention are highly suitable as cosmetic compositions for the care and / or cleansing of keratinous materials, since they are able to provide the keratinous materials with the benefit of the biological activity provided by glycolipids, whilst exhibiting improved stability.
