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.

Liquid detergent composition

A hair cosmetic is disclosed which comprises the following components (A), (B) and (C):

Hair cosmetic containing a cationic surfactant, fat and oil and an alkyl

A low-irritant detergent composition comprising (A) an alkyl saccharide surfactant and (B) a sucrose fatty acid ester surfactant, and, optionally, (C) an anionic surfactant or amphoteric surfactant is disclosed. The composition is low-irritant to the skin and hair and produces creamy and abundant foam, giving an excellent slippery feel to the skin and the hair.

Detergent composition

A detergent composition comprising a phosphate-type surface active agent and an alkyl saccharide-type surface active agent is described. The phosphate-type surface active agent which can be used have the following formula (I) or (II), and the alkyl saccharide-type surface active agent have the following formula (III): ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, and R.sub.4 represent a linear or branched alkyl, alkenyl group, or alkyl phenyl groups of a C.sub.8-18 carbon atom content, X and Y represent a hydrogen atom, an alkali metal, an ammonium, or an alkanol amine having a hydroxyl alkyl group of a C.sub.2-3 carbon atom content, R.sub.5 represents an alkylene group of a C.sub.2-4 carbon atom content, G represents a reduced sugar of a C.sub.5-6 carbon atom content, and 1, m, n, and p denote a value of 0 to 10. The detergent composition exhibits exceptionally good detergent capability and foaming capability. In addition, it imparts less irritation to the hair and skin, less creaking feeling to the hair, and superior smooth and moistened feeling to the skin.

The detergent composition exhibits exceptionaly good detergent capability and foaming capability. In addition, it imparts less irritation to the hair and skin, less creaking feeling to the hair, and superior smooth and moistened feeling to the skin.

A low-irritation detergent composition comprising (A) an alkyl saccharide-type surface active agent and (B) a cationic polymer. The composition is a low irritant to the skin and hair, produces excellent creamy foam, possesses a superior hair conditioning effect, and imparts an outstanding moisture feeling to the skin.

Low-irritation detergent composition

A detergent composition comprising an alkylsaccharide surface active agent and a silicone derivative is disclosed. The composition can produce fine, slippery, creamy foam, imparts the least irritation to the skin and hair, a tense, slippery feeling to the hair, and a light, refreshing feeling to the skin. The detergent composition thus can be favorably used as a shampoo and a body shampoo.

Mild liquid aqueous detergent compositions containing an alkylsaccharide

A low-irritant detergent composition comprising alkyl saccharide surfactant and sulfosuccinate surfactant is disclosed. The detergent composition possesses excellent foaming capability and low-temperature stability. The detergent composition also imparts fine feeling when used as a detergent for the hair and the skin without irritation to the skin.

Low-irritant detergent composition containing alkyl saccharide and

Mild cosmetic cleansing foams containing an HlB3-8 nonionic surfactant

Lactic acid esters of an .alpha.-branched fatty acid possessing an excellent hair conditioning effect are disclosed. Typical example is sodium 2-heptylundecanoyl acid lactate prepared by the reaction of 2-heptylundecanoic acid and lactic acid in the presence of an alkali such as sodium hydroxide. This compound gives a shampoo composition in conjunction with an anionic surface active agent, and a hair rinse composition when a quaternary ammonium salt is formulated. The compositions have excellent conditioning effects on use such as good slipperiness and hair curling formation or retention performance.

Novel fatty acid-lactic acid ester

A water-soluble viscosity increasing agent consisting essentially of: (i) an ester of a 40 to 400 moles ethylene oxide adduct of polyhydric alcohol and a C.sub.8-36 branched fatty acid, (ii) an ester of polyethylene glycol having average molecular weight of 2,000 to 20,000 and a C.sub.8-36 branched fatty acid, and (iii) a 40 to 400 mole ethylene oxide adduct of an ester of a polyhydric alcohol and a C.sub.8-36 branched fatty acid. The viscosity increasing agent can increase the viscosity of solutions of various surface active agents, while maintaining their stability and solubility in the solutions. When it is formulated to a detergent suitable for washing textiles, tablewares, human skins, hairs and the like, it can provide a detergent composition with a proper viscosity as well as a good detergency.
