抄録

Phosphate which has been formulated in synthetic detergents for many years, is now often considered to accerelate eutrofication. In this connection, an intensive search is being made by the detergent industries for phosphate substitutes.<BR>Japan Oil Chemists' Society has been entrusted in regard to the method of reducing phosphates in detergents by the Ministry of International Trade and Industry.<BR>In order to obtain more reliable soil removal data, it was decided to incorporate bundle testing into our detergency evaluation scheme.<BR>Bundle testing, compaing four laundry detergents, A : (STPP 10% as P2O5), B : (STPP 5% as P2O5), C : (STPP 0 % as P2O5), D : (STPP 5 % as P2O5, Zeolite 8.5%), and using naturally soiled family items such as dress shirts, shirts, socks etc., under controlled conditions, has been performed.<BR>For over ten months, 14 oil and surface chemists, 40 research assistants and 48 families (192 panelers) were engaged in this project.<BR>In our laborious experience, it was concluded that phosphate has proved useful and detergency lowered with decreasing phosphate in detergents, while certain amount of sodium almino silicate “Zeolite” may be used as a substitute to reduce the total amount of phosphate.
