[0014] The present invention relates to a cleansing cosmetic containing a lactic acid bacteria fermentation product obtained by fermenting an aloe-containing medium with lactic acid bacteria (hereinafter referred to as an "aloe lactic acid bacteria fermentation product," "lactic acid bacteria fermentation product (aloe)," or "lactic acid bacteria fermentation extract (aloe)," etc.), particularly a cleansing cosmetic containing a surfactant. Here, the cleansing cosmetic can be in any desired form, such as an aqueous solution, emulsion, or gel, and can include hair cleansing cosmetics such as shampoos and body cleansing cosmetics such as soaps.

[0015] Aloe lactic acid bacteria fermentation product The aloe lactic acid bacteria fermentation product of the present invention is essentially obtained by culturing lactic acid bacteria in a medium containing aloe.

[0016] The aloe contained in the medium is a general term for a plant of the liliaceae family native to Africa, and includes over 300 varieties, including Aloe arborescens and Aloe vera. This aloe is known to contain a large amount of polysaccharides, such as mucin and aloemannan, as well as components such as aloin, aloenin, aloetin, arotimin, and aloe ursin. The aloe used in one embodiment is not particularly limited as long as it is a member of the Aloe family, but Aloe arborescens or Aloe vera is preferred, particularly from the perspectives of availability and cost. The parts of the aloe used are not particularly limited, but in addition to leaves, mesophyll, buds, and roots, juices and drips from these parts, as well as various components derived therefrom, can also be used, as these parts lack fiber and therefore simplify subsequent manufacturing processes.

[0017] However, since many lactic acid bacteria cannot assimilate the fiber components and proteins in aloe, it is preferable to subject the aloe to degradation treatments such as cellulase treatment and protease treatment before fermentation, as per conventional methods. Cellulase treatment improves assimilation and allows fermentation to proceed, eliminating unassimilated cellulose and other components in the aloe lactic acid bacteria fermentation product, simplifying subsequent production steps. Furthermore, protease treatment eliminates protein components and other components from remaining in the aloe lactic acid bacteria fermentation product, preventing turbidity and allowing the elimination of a clarification step after fermentation. Furthermore, the assimilation of lactic acid bacteria can be further improved by combining amylase treatment. For the enzymatic hydrolysis treatment, one or more enzymes may be appropriately selected from the following: fibrous enzymes (cellulases) such as cellulase and pectidase; protease enzymes (proteases) such as acid protease, neutral protease, alkaline protease, proteinases such as papain, ficin, and bromelain, peptidase, and mannanase; and starch-degrading enzymes (amylases) such as α-amylase and glucoamylase. Since lactic acid bacteria can sufficiently utilize aloe by subjecting them to the above-mentioned treatments as needed, it is usually not necessary to supply other carbon sources (e.g., sugars) during fermentation. Furthermore, adding sugars to aloe during fermentation may change the sensory characteristics of the resulting aloe lactic acid bacteria fermentation product. In cases where such changes could impair the palatability of the final product, it is preferable not to add sugars to aloe.

[0018] The lactic acid bacteria used for fermentation are preferably Lactobacillus lactic acid bacteria, more preferably Lactobacillus plantarum. Alternatively, in addition to Lactobacillus plantarum, other lactic acid bacteria may be used for fermentation, such as Lactobacillus casei, Lactobacillus crispus, Lactobacillus amylovorus, Lactobacillus brevis, Lactobacillus buchneri, Lactobacillus fermentum, Lactobacillus mali, Lactobacillus parabuchneri, Lactobacillus paracasei, Lactobacillus pentosus, Lactobacillus rhamnosus, Lactobacillus vitulinus, Lactobacillus zeae, and other Lactococcus lactis. Examples of lactic acid bacteria include the genus Leuconostoc, such as Leuconostoc mesenteroides, Leuconostoc carnosum, Leuconostoc citreum, Leuconostoc gelidum, and Leuconostoc lactis; the genus Pediococcus, such as Pediococcus pentosaceus; the genus Enterococcus, such as Enterococcus faecalis and Enterococcus faecium; the genus Weissella, such as Weissella confusa, Weissella paramesenteroides, and Weissella viridescens; and the genus Streptococcus, such as Streptococcus thermophilus. One or more of the lactic acid bacteria listed above may be used.

[0019] To ferment an aloe-containing medium with lactic acid bacteria, for example, the Brix is preferably 3.0 or higher, and preferably 3.3 or higher. Furthermore, the aloe extract, whose pH has been adjusted to 4.2 or lower (preferably 4.0 or lower), is adjusted with water to a dry solids content of 0.5 to 20% by weight, preferably 1 to 10%, to prepare a medium. Lactic acid bacteria are inoculated into the medium at 0.01 to 10% by weight, preferably 0.1 to 5% by weight, and the medium is cultured at 20 to 40°C, preferably 25 to 40°C, for 6 to 96 hours, and preferably 24 to 96 hours. Other culture conditions include standing, stirring, shaking, aeration, etc., and a method suitable for culture may be selected from these.

[0020] To supplement the nutritional sources for culturing lactic acid bacteria, the aloe-containing medium may contain other commonly used ingredients, provided that the effects of the present invention are not impaired. Examples of such ingredients include yeast extract, chlorella extract, vitamins such as vitamin A, vitamin B, vitamin C, and vitamin E, protein hydrolysates including various peptides, amino acids, salts such as calcium and magnesium, surfactants such as polysorbate 80, fatty acids such as oleic acid, and metals such as calcium, magnesium, and manganese.

[0021] The aloe lactic acid bacteria fermentation product obtained as described above can be subjected to known purification and separation processes such as filtration, dialysis, precipitation, and centrifugation, as well as extraction processes using solvents, heat treatment, freeze-drying, and concentration to dryness.

[0022] For example, one embodiment of the aloe lactic acid bacteria fermentation product of the present invention may be a supernatant obtained from fermenting an aloe-containing medium with lactic acid bacteria.

[0023] The supernatant obtained by fermenting this aloe-containing medium with lactic acid bacteria is obtained by removing solids from the aloe lactic acid bacteria fermentation product obtained as described above using standard methods such as centrifugation, filtration, etc. As mentioned above, the supernatant may be further treated by dialysis, solvent extraction, heating, freeze-drying, and / or concentration and coagulation.

[0024] In one embodiment, the content of the aloe lactic acid bacteria fermentation product in the cleansing cosmetic of the present invention can be 0.3 to 3.0 wt % in terms of dry solid content of the total composition, and particularly preferably 1.0 to 2.5 wt %.

[0025] Cleansing cosmetics The cleansing cosmetic composition of the present invention contains a surfactant. In one embodiment of the cleansing cosmetic composition of the present invention, an ionic surfactant can be used as the surfactant, and among these, an anionic surfactant and an amphoteric surfactant are preferably used.

[0026] The anionic surfactants that can be used in the present invention include various surfactants such as carboxylate-based anionic surfactants, higher alcohol-based anionic surfactants, sulfonate-based anionic surfactants, phosphate-based anionic surfactants, amino acid-based anionic surfactants, etc. For example, alkyl (or alkenyl) sulfates, polyoxyalkylene alkyl (or alkenyl) ether sulfates, alkanesulfonates, olefinsulfonates, alkylbenzenesulfonates, alkyl (or alkenyl) sulfosuccinates, dialkyl (or dialkenyl) sulfosuccinates, polyoxyalkylene alkyl (or alkenyl) sulfosuccinates, alkyl (or alkenyl) ether carboxylates, polyoxyalkylene alkyl (or alkenyl) ether carboxylates, polyoxyalkylene alkyl (or alkenyl) ether phosphates, fatty acid salts, N-acyl glutamates, N-acyl taurates, N-acyl methyl taurines, etc. can be used in the present invention. Among these, the anionic surfactant according to one embodiment of the present invention is preferably a higher alcohol-based surfactant (particularly, one having 12 or more carbon atoms). In another embodiment of the present invention, the surfactant is preferably a polyoxyethylene-based anionic surfactant having an ethylene oxide moiety. Specifically, sodium laureth sulfate, sodium dodecyl sulfate, and sodium methyl cocoyl taurate are particularly preferred, but are not limited to these.

[0027] The above-mentioned anionic surfactants can be obtained as commercial products in the form of an aqueous solution either as is or formulated with other accessory components, and examples of such products include EMAL (registered trademark) 20C (manufactured by Kao Corporation) and DIAPO K-SF (manufactured by NOF Corporation).

[0028] In another embodiment of the present invention, the surfactant is preferably an amphoteric surfactant. As the amphoteric surfactant, glycine type, alkyl betaine type, alkyl amide betaine type, amine oxide type, aminopropion type, etc. can be used, among which glycine type sodium cocoamphoacetate is preferred. Such amphoteric surfactants can also be commercially available, for example, Softazoline CH (manufactured by Kawaken Fine Chemicals Co., Ltd.).

[0029] In the cleansing cosmetic composition of the present invention, the surfactant may be selected from the above-listed surfactants alone or in combination of two or more thereof.

[0030] In addition to water, a lactic acid bacteria fermentation product, and a surfactant, the cleansing cosmetic composition according to one embodiment of the present invention can contain various additives depending on the purpose. For example, the cleansing cosmetic composition can contain antibacterial agents such as butylene glycol and 1,2-pentanediol, cooling agents such as menthol and ethanol, preservatives such as methylparaben, sodium benzoate, and phenoxyethanol, salts such as sodium chloride, pH adjusters such as citric acid, propellants such as dimethyl ether, fragrances, colorants, etc.

[0031] In one embodiment, the content of surfactant incorporated into the cleansing cosmetic of the present invention can be adjusted appropriately based on the desired foaming properties, foam stability, etc., and can be, for example, 0.1 to 20 wt %, 0.2 to 15 wt %, 0.3 to 12.5 wt %, 0.5 to 10 wt %, 1.0 to 5.0 wt %, 1.2 to 3.0 wt %, or 1.5 to 2.5 wt % of the total composition. When the cleansing cosmetic is composed only of water, a lactic acid fermentation product, and a surfactant, the content of surfactant incorporated into the cleansing cosmetic is preferably 0.1 to 12.5 wt %, and particularly preferably 0.3 to 2.5 wt % of the total composition.

[0032] The amount of surfactant blended into the cleansing cosmetic can be adjusted depending on the type and amount of additives. For example, when butylene glycol or cocamide DEA is used as an additive, the amount is preferably 1.5 to 4.0 wt. %, and more preferably 1.5 to 3.0 wt. %.

[0033] The cleansing cosmetic composition of the present invention can be prepared by any technique known to those skilled in the art as suitable for blending the essential components (aloe fermentation product and surfactant) and optional components (various additives, etc.) of the composition to form a physically stable composition, preferably a liquid composition, suitable for application to hair or skin. For example, all of the components can be mixed at once, or a combination of some of the components can be mixed in any order, in water or other aqueous solvents (ethanol, glycerol, etc.) or mixtures thereof, and further diluted with water, etc., if necessary.

[0034] Foaming enhancers and foam stability enhancers Therefore, the aloe lactic acid bacteria fermentation extract of the present invention may be added to a cleansing cosmetic in the form of a foaming improver and / or a foam stability improver for the cleansing cosmetic. The foaming improver and foam stability improver may be the aloe lactic acid bacteria fermentation product of the present invention itself as an active ingredient, or may be in the form of a composition that may optionally contain, for example, an antibacterial agent, a preservative, a pH adjuster, etc.

[0035] The foaming improver and foam stability improver of the present invention are added to the cleansing cosmetic of the present invention in amounts such that the content of the aloe lactic acid bacteria fermentation product of the present invention in the cleansing cosmetic falls within the above-mentioned ranges. That is, by adding the aloe lactic acid bacteria fermentation product of the present invention in this manner, the foaming property and / or foam stability of the cleansing cosmetic are improved.
