A cleanser composition comprising a phosphate type surfactant and an amide ether carboxylic acid as the essential components. This cleanser composition is lowly irritant to the skin etc., and excellent in lathering property, gives creamy foam in quality, and can give an excellent feeling to the skin cleansed even when it is used in hard water.

Cleanser composition

The present invention relates to a detergent composition which comprises (A) an amidoether derivative mixture (A) comprising an amidoether carboxylic acid or a salt thereof, an amidoether, and a glycerin derivative; and (B) a conditioning component, wherein the total amount of the amidoether carboxylic acid or a salt thereof and the amidoether is 50 wt % or more; the weight ratio of the amidoether carboxylic acid or a salt thereof to the amidoether is from 99:1 to 10:90; and the amount of the glycerin derivative is 5 wt % or less.

Detergent composition comprising an amidoether derivative mixture and a

A detergent composition comprising (a) 0.1 to 95% by weight of a saccharide nonionic surfactant and (b) 0.01 to 5% by weight of an antibacterial agent. The detergent compositions are outstandingly mild to the skin, exhibiting a high antibacterial effect, without influencing or weakening the cutaneous metabolic and barrier functions of the skin. The detergent compositions can effectively restrain the early occurrence of dandruff after shampooing when used as detergents for the scalp and the hair. They also exhibit high antibacterial effect when used as body detergents.

A process for preparing glucose-1-phosphate from an .alpha.-glucan and orthophosphate using a phosphorylase immobilized onto an anion-exchange resin is disclosed. The anion-exchange resin used is a synthetic polymer resin into which an anion exchange group; a primary to quarternary ammonium group, a phosphonium group, or a sulfonium group, is introduced. This type of immobilized phosphorylase ensures (i) an effective utilization of phosphorylase, (ii) a higher reactivity of a higher absorbance of the phosphorylase to the resin, (iii) an excellent phosphorylase activity retention performance, and (iv) a higher physical strength of the resin.

Immobilized phosphorylase
