Description

The technology disclosed in the present application relates to a cleansing cosmetic containing a fermented product of lactic acid bacteria and a surfactant, and a method for producing the same.

In general, cleansing cosmetics such as soaps and shampoos are required to have improved foamability and foam stability from the viewpoint of detergency and user satisfaction during cleansing. In this respect, various improvements have been reported from the viewpoint of surfactants contained in various cleansing cosmetics, but they are still not sufficient. Further improvement is required.

On the other hand, fermented products of lactic acid bacteria are said to have an effect of improving skin wrinkles and sagging, and are generally blended in lotions, basic cosmetics, and the like. Aloe extracts have also been reported to exhibit skin moisturizing effects and hair growth effects (for example, Patent Documents 1 and 2). However, the influence of lactic acid fermented products, particularly lactic acid fermented products derived from media containing aloe, on foamability and foam stability is unknown.

The present invention is a lactic acid fermented product obtained by fermenting an aloe-containing medium with lactic acid bacteria (hereinafter referred to as "lactic acid fermented product of aloe", "lactic acid fermented product (aloe)", or lactic acid fermented extract (aloe)". ), particularly to a cleansing cosmetic containing a surfactant. Here, the cleansing cosmetics include hair cleansing cosmetics such as shampoos and body cleansing cosmetics such as soaps in desired forms such as aqueous solutions, emulsions and gels.

Aloe Lactic Acid Bacteria Fermented Product The aloe lactic acid bacterium fermented product of the present invention is essentially obtained by culturing lactic acid bacteria in a medium containing aloe.

Aloe contained in the medium is a general term for plants of the Liliaceae family native to Africa, and has more than 300 varieties such as aloe vera and aloe vera. This aloe contains many polysaccharides such as mucin and aloemannan, and is known to contain components such as aloin, aloenin, aloetin, arothymine, and aloeursin. The aloe used in one embodiment is not particularly limited as long as it is a member of the aloe family, but it is preferable to use aloe vera or aloe vera from the standpoints of availability and cost. The part of the aloe vera used is not particularly limited, but in addition to the leaves, mesophyll, buds, and roots, the sap and drip of the part, which facilitates the subsequent manufacturing process because there are no fibrous components, and various components obtained therefrom. etc. can also be used.

By the way, since many lactic acid bacteria cannot assimilate the fibrous components, proteins, etc. in the aloe, it is possible to subject the aloe to decomposition treatment such as cellulase treatment, protease treatment, etc. before fermentation treatment according to a conventional method. preferable. By performing the cellulase treatment, the assimilation property is improved and the fermentation proceeds, and the cellulose that could not be assimilated does not remain in the fermented product of the lactic acid bacteria of aloe, and the subsequent production steps are simplified. In addition, by performing protease treatment, protein components and the like do not remain in the fermented product of lactic acid bacteria of aloe, so that turbidity does not occur, and a clarification step can be omitted after fermentation. Furthermore, by using amylase treatment together, the assimilation of lactic acid bacteria can be further improved. For enzymatic degradation treatment, fibril-degrading enzymes (cellulases) such as cellulase and pectitase, proteolytic enzymes such as acid protease, neutral protease, alkaline protease, papain, ficin, bromelain, etc., peptidase, mannanase, etc. (proteases), α-amylase, glucoamylase, and other amylolytic enzymes (amylases) may be appropriately selected and used. In addition, since lactic acid bacteria can fully assimilate aloe by performing the above-described treatment as necessary, it is usually not necessary to daringly supply other carbon sources (eg, sugars) during fermentation. In addition, the addition of sugars to aloe during fermentation may change the sensory characteristics of the resulting lactic acid bacteria fermented product, and such changes may impair the palatability of the final product. Preferably no sugars are added to the aloe.

As lactic acid bacteria used for fermentation, lactic acid bacteria belonging to the genus Lactobacillus are preferable, and Lactobacillus plantarum is more preferable. Alternatively, lactic acid bacteria used for fermentation other than Lactobacillus plantarum include, for example, Lactobacillus casei, Lactobacillus crisvertus, Lactobacillus amylovorus, Lactobacillus brevis, Lactobacillus buchneri, Lactobacillus fermentum, Lactobacillus genus such as Lactobacillus mari, Lactobacillus parabufuneri, Lactobacillus paracasei, Lactobacillus pentosus, Lactobacillus rhamnosus, Lactobacillus bitulinus, Lactobacillus zeae, Lactococcus genus such as Lactococcus lactis, Leuconostoc such as Leuconostoc mesenteroides, Leuconostoc carnosum, Leuconostoc citreum, Leuconostoc geridum, Leuconostoc lactis; Pediococcus such as Pediococcus pentosaceus; Lactic acid bacteria of the genus Enterococcus such as Faecalis and Enterococcus faecium, the genus Weissella such as Weissella confusa, Weissella paramesenteroides, and Weissella viridescens, and the genus Streptococcus such as Streptococcus thermophilus. In addition, 1 type of the lactic acid bacteria listed above may be used, and 2 or more types may be used.

Culture may be performed for 24 to 96 hours. Other culture conditions at this time include standing, stirring, shaking, aeration, and the like, and a method suitable for culture may be appropriately selected from these.

For the purpose of supplementing the nutrient source in the culture of lactic acid bacteria, the aloe-containing medium may additionally contain commonly used components as long as the effects of the present invention are not impaired. Such ingredients include yeast extract, chlorella extract, vitamins such as vitamin A, vitamin B, vitamin C, and vitamin E, protein hydrolyzate including various peptides, amino acids, salts such as calcium and magnesium, and polysorbate. surfactants such as 80, fatty acids such as oleic acid, and metals such as calcium, magnesium and manganese.
