A detergent composition is disclosed. The composition comprises polymer particles having an average particle size of 50-500 .mu.m in 5% by weight sodium chloride aqueous solution and a modulus of elasticity of 1.times.10.sup.3 -5.times.10.sup.5 dyne/cm.sup.2 in said sodium chloride aqueous solution. It exhibits a superior physical or mechanical washing performance, and gives remarkably reduced irritation and minimal damage to the object being washed. When a germicide is incorporated in addition to the polymer particles, its sterilization effect is greatly enhanced.

Detergent composition

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.

There is disclosed a hair cleansing composition having excellent detergency against oily dirts such as aged high-viscosity silicone compounds. The composition comprises the following components (a) to (d):

Hair cleansing composition

A skin detergent composition comprises (a) 5 to 95 percent by weight of a phosphoric acid ester having the formula (I) or (II) and (b) 0.0005 to 0.1 percent by weight of a water-soluble chitin compound.

Skin detergent composition containing a phosphate ester surfactant and a

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

A composition for a hair treatment agent comprising as essential components: a chelating agent having a specific chelating value with respect to the chelation of the calcium ion, and a polymer compound selected from a group consisting of cationic polymers containing quaternary nitrogen, and peptides of an average molecular weight of 40 to 10,000, or their derivatives. The composition provides a perm-treatment with a good finishing effect by depressing absorption of calcium to the hair when it is perm-treated. It also serves as a shampoo, by further formulating an anionic or amphoteric surface active agent, which gives an excellent effect of suppleness and smoothness after washing and rinsing to hair which is damaged from a perm treatment.

Composition for hair treatment agent

A detergent composition is disclosed, which comprises (A) 0.1 to 40% by weight of at least one kind of anionic or amphoteric surface active agents and (B) 0.05 to 4% by weight of at least one kind of quaternary ammonium salts represented by the following formula (I) or (II): ##STR1## wherein R.sub.1 represents a mixture of (a) a branched alkyl group represented by ##STR2## and (b) a linear alkyl group represented by CH.sub.3 --(CH.sub.2).sub.n -- wherein R.sub.7 represents a methyl or ethyl group, m is an integer to make the carbon atom content of the branched alkyl group to 8 to 16, and n is an integer of 7 to 15), with a ratio (a)/(a)+(b) being 0.1 to 1, R.sub.2 and R.sub.3 independently represent a benzyl group, an alkyl group having 1 to 3 carbon atoms, or a hydroxyalkyl group having 1 to 3 carbon atoms, R.sub.4 and R.sub.5 independently represent an alkyl group having 2 to 12 carbon atoms, R.sub.6 represents a group ##STR3## or an alkyl group having 1 to 3 carbon atoms, and X.sup.- represents a halogen ion or an organic anion. The detergent composition provides a shampoo with superb hair conditioning effects; softness and smoothness after washing, less sticky feeling, easy passage of comb through the hair, less hard or rough feeling as well as easy hair-set performance after drying. The detergent composition also provides a liquid detergent suitable for washing cloths made of wool or made of fine denier fibers.

Detergent composition comprising an anionic or amphoteric surface active

A surface active agent comprising a specific type of secondary amidoamino acid or ammonium ion or triethanolammonium salt thereof, ##STR1## as a major component, and not more than 0.2 mole of an inorganic salt per 100 gm of said secondary amidoamino acid or 100 gm of a salt thereof as converted to the acid type secondary amidoamino acid. The surface active agent can be prepared by subjecting the alkali metal salt of secondary amidoamino acid, usually containing a great amount of impurities such as sodium chloride, to electrodialysis. It has excellent compatibility with various additives such as water-soluble polymer due to its low ionic strength and yet exhibits a good low-temperature stability when made into an aqueous solution owing to its low Krafft point.

Surface active secondary amidoamino acid or salt compounds

A novel detergent composition comprising as a main detergent active ingredient a secondary amidoamino acid or its salts of the following general formula (I): ##STR1## The detergent composition has low irritativeness and good detergency, so that it is appropriately used as hair and skin detergents for babies, dish wash detergents and the like.

Secondary amidoamino acid based detergent composition

A polyvalent metal salt of 2-mercaptopyridine-N-oxide (Mept compound) is dispersed in water by aid of a specific dispersant selected from the group consisting of (A), (B) and (C):

Antimicrobial suspensions and antimicrobial hair treatment compositions

Novel detergent composition comprises one or more of N-acyl-N-hydroxyalkylglycines of the general formula (I) or salts thereof: ##STR1## The composition has a very good resistance to hard water, low stimulativeness, and good detergency. It is thus suitably employed as shampoo for babies, kitchen detergent and the like.

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.
