A single-dose detergent formulation having a hydrophobically modified polymer and useful for either laundry or auto dishwashing applications is presented. The polymer consists of a hydrophilic backbone to which a hydrophobic moiety has been added by means of at least one hydrophobic monomer, chain transfer agent, or surfactant. The hydrophobically modified polymer is soluble in non- aqueous solvents, and useful in sachets or pouches for single-dose applications. The polymer also inhibits the corrosion of aluminum, and is therefore useful in applications such as cleaning and deicing, or in a metal- working fluid.
Cette invention concerne un préparation détergente sous forme de dose unique renfermant un polymère à hydrophobie modifiée convenant bien pour des lave-linge ou des lave-vaisselle automatiques. Ce polymère est constitué par une structure hydrophile à laquelle on a ajouté une fraction hydrophobe sous forme d'au moins un monomère hydrophobe, d'un agent de transfert de chaînes ou d'un tensioactif. Le polymère à hydrophobie modifiée est soluble dans des solvants non aqueux et convient bien en dose unique, en paquet ou en sachet. Ce polymère freine la corrosion de l'aluminium et se prête à des applications telles que le nettoyage, le dégivrage, ou bien comme fluide pour le travail des métaux.
