Abstract: A bleaching composition which may serve as a detergent comprises hydrogen peroxide and a bleaching activator having a cationic group and having the formula (I) in which L is an ester-having phenyl and an amide-having phenyl: ##STR1##

Abstract: A bleaching composition comprises a peroxide and an amphoteric organic per acid precursor. In particular the amphoteric organic per acid precursor is a quaternary ammonium salt has the following formula in which Z is sulfonate or carboxylate and is a new compound.

Abstract: A softener composition comprising a quaternary ammonium salt having two hydrocarbon radicals having 12-22 carbon atoms and one unsaturated bond; the stereoisomeric structure of the above salt includes both the cis-isomer and the trans-isomer with the cis-isomer/trans-isomer ratio being in the range of from 25/75-90/10.

Abstract: A bleaching composition comprises a peroxide and an amphoteric organic per acid precursor. In particular the amphoteric organic per acid precursor is a quaternary ammonium salt has the following formula in which Z is sulfonate or carboxylate and is a new compound.

Abstract: 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.

Abstract: 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.

Abstract: A novel process for preparing an alkanolammonium salt or ammonium salt of an amino acid surface active agent or an acylated amino acid surface active agent. In the process, an alkali metal salt of an amino acid surface active agent or acylated amino acid surface active agent is subjected to electrodialysis in the presence of a mineral acid salt of an alkanolamine or ammonia, or a mixture of an alkanolamine or ammonia and a mineral acid.By-products which are produced during the preparation of the above surface active agents can be mostly removed to outside during the electrodialysis and are thus purified conveniently.
