A method for perming or coloring hair, in which hair is treated with a cosmetic composition including a protein-glutaminase and not including an alkaline substance. A method of enhancing hair-permeation of an active ingredient included in a cosmetic composition, in which a protein glutaminase is included in the cosmetic composition. The cosmetic composition does not include an alkaline substance, and the active ingredient is at least one of a hair perm agent and a hair coloring agent.

Cosmetic composition

The present invention provides a cosmetic composition containing (A) a powder composed of one or more kinds of the N-medium-chain-acyl basic amino acid powder represented by the following formula (I), (B) an inorganic powder, and (C) an oil material: wherein R is a saturated or unsaturated straight hydrocarbon group having 5-9 carbon atoms, and m is an integer of 1-4.

The present invention provides a composition containing (A) and (B), which shows a decreased peculiar odor of acylproline and a salt thereof, has a moist feeling and is superior in the stability: (A) acylproline represented by the formula (1) or a salt thereof (wherein an acyl group represented by R&#x2014;CO&#x2014; is an acyl group induced from saturated or unsaturated fatty acid having 3-23 carbon atoms)(B) a zinc salt of pyrrolidone carboxylate.

Moisturizer and cosmetic containing same

Provided is a composition containing a sterol ester, which is an oil poorly soluble in water, and superior in transparency, stability, foaming property, rinsability, skin feel (during rinsing and/or after use), and emollience. A composition containing

Liquid cleanser comprising sterol ester and C5-6 hydroxyalcohol

Provision of an N-acyl basic amino acid dispersion superior in dispersibility. The present invention provides a production method of an N-acyl basic amino acid dispersion having a pH of 2 to 12, comprising

N-acyl basic amino acid dispersion

Aqueous preservative solutions with a high amino acid content which is excellent in preservation, particularly a preservative effect on fungi, and safety, and is excellent in storage stability so as not to cause a problem such as depositing, coloring or smelling even when it is stored for a long time, and when incorporated in a cosmetic, is capable of imparting a high moisturizing effect without causing a sticky feeling, and imparting an effect of preventing dyed hair from color fading, can be achieved by incorporating pyrrolidone carboxylic acid and/or a salt thereof (Component A), a basic amino acid and/or a salt thereof (Component B), an acidic amino acid and/or a salt thereof (Component C), a neutral amino acid and/or a salt thereof (Component D) and lactic acid and/or a salt thereof (Component E) at a specific incorporation ratio and at a specific pH.

Aqueous preservative solution with high amino acid content

A detergent composition comprising (A) 5 to 30% by weight of at least one kind of surfactant selected from the group consisting of an anionic surfactant, an amphoteric surfactant, and a nonionic surfactant based on the total weight of the composition; (B) 0.1 to 5% by weight of a substance selected from the group consisting of an N-long-chain acyl acidic amino acid and a salt thereof based on the total weight of the composition; and (C) less than 0.2% by weight of a cationic polymer compound based on the total weight of the composition. The detergent composition provided has good foaming property and causes no friction during rinsing, as well as has excellent feeling of use by imparting moistness without tackiness to skin and providing good hair control without stiffness.

Detergent composition

A cleansing composition containing a N-long-chain-acylated dipeptide and an N-long-chain-acylated acidic amino acid. The cleansing composition exhibits low skin irritation, excellent resistance to hard water, is free from turbidity and the unpleasant odor associated with some natural peptides. The composition also provides excellent skin and hair feel qualities during and after use.
