Description

The present invention relates to compositions.

Conventionally, cosmetics such as shampoos, body soaps, and hand soaps, household detergents for tableware and clothes, and daily necessities such as mouthwashes and toothpastes contain various surfactants such as nonionic, anionic, and amphoteric surfactants. is These surfactants are selected according to the purpose and application, such as functions such as detergency, usability such as foaming and viscosity suitable for use, and sensory properties such as finger combing during rinsing. Used.

So far, sulfuric acid-based or olefinsulfonic acid-based anionic surfactants, which have high foaming properties, detergency, and appropriate viscosity, have been widely used. However, in cosmetics that are applied directly to the hair or skin, due to the growing interest in scalp and skin care, cosmetics that use less irritating amino acid-based surfactants as anionic surfactants are gaining popularity. In addition, the development of cosmetics labeled as "sulfate-free" is also underway.

Compared to conventional anionic surfactants, amino acid-based surfactants are less irritating surfactants that have cleansing action without damaging the skin and hair, and are manufactured using natural raw materials. Therefore, it is considered to be useful as an environmentally friendly and sustainable surfactant (see, for example, Patent Document 1). So far, techniques using amino acid-based surfactants have been studied, for example, a thickening composition containing an amino acid-based surfactant and a specific (meth)acrylic acid-based copolymer (e.g., Patent Document 2 See), at least one selected from a specific fatty acid salt, 2-ethylhexyl glyceryl ether and a fatty acid ester having a fatty acid residue having 4 to 10 carbon atoms, and an N-acyl amino acid surfactant, a specific containing A skin cleanser composition with a specific amount and ratio (see, for example, Patent Document 3) and the like have been proposed.

As described above, it can be said that development of a new composition using an amino acid-based surfactant is required in consideration of irritation, environmental load, etc. while maintaining conventional functions.

However, the techniques of Patent Documents 1 to 3 do not mention the occurrence of clouding and solidification over time in a composition containing cocoylglycine or a salt thereof, which is an amino acid surfactant. As described above, no consideration has been given to the stability over time of compositions containing cocoylglycine or salts thereof.

Accordingly, an object of the present invention is to provide a composition containing cocoylglycine or a salt thereof, betaine lauryldimethylaminoacetate and lauroylmethylalanine or a salt thereof, which exhibits excellent stability over time.

Still another object of the present invention is to provide a composition that is excellent in foaming and foam retention.

The present inventor has investigated the development of a composition that is excellent in foaming and foam retention without containing a sulfuric acid-based or olefin sulfonic acid-based surfactant. It was found that salt exhibits excellent effects. However, the composition containing cocoylglycine or a salt thereof causes clouding and solidification over time, leaving room for improvement. Therefore, as a result of examining the combination of surfactants, it was found that by containing betaine lauryldimethylaminoacetate and lauroylmethylalanine or a salt thereof at a specific content ratio, clouding and solidification over time are suppressed, and transparent to translucent The present inventors have found that the composition is stable enough to maintain a smooth appearance, and that the composition is excellent in good foaming and good foam retention, thereby completing the present invention.
