Patent

CA 2177057

In a particulate detergent composition containing 10 wt % or more of mobile ethoxylated nonionic surfactant, the incorporation of a graft copolymer of polyethylene, polypropylene or polybutylene oxide with vinyl acetate/alcohol reduces bleeding out of nonionic surfactant as well as providing the known soil release benefit. Preferred compositions of the invention also contain sodium citrate and are of high bulk density.

Dans une composition détergente particulaire contenant 10% en poids ou davantage d'un tensioactif mobile, non ionique et éthoxylé, l'incorporation d'un copolymère greffé d'oxyde de polyéthylène, de polypropylène ou de polybutylène avec de l'acétate/alcool de vinyle, réduit le phénomène de migration du tensioactif non ionique tout en offrant les avantages connus d'enlèvement de la saleté. Des compositions préférées selon l'invention contiennent également du citrate de sodium et possèdent une masse volumique en vrac élevée.
