摘要:
The present invention relates to isotropic enzymatic liquid detergent compositions comprising lipolytic enzymes. The stability of the lipolytic enzymes is significantly improved therein by inclusion of particular nonionic ethylene glycol containing copolymers therein. These polymers comprise ethylene oxide or ethylene glycol, copolymerized with difunctional acids or acrylic based copolymers. Isotropic liquids are obtained without the aid of hydrocarbon solvents.The compositions preferably also contain proteolytic enzymes.

The present invention relates to thickened personal care compositions which utilize a thickening amount of an acrylate-based polymeric rheology modifier prepared by polymerization of a C.sub.1 -C.sub.6 alkyl ester of acrylic acid and/or a C.sub.1 -C.sub.6 alkyl ester of methacrylic acid, a monomer chosen from a vinyl-substituted heterocyclic compound containing at least one of a nitrogen or sulfur atom, (meth)acrylamide, a mono- or di-(C.sub.1 -C.sub.4)alkylamino (C.sub.1 -C.sub.4)alkyl (meth)acrylate, a mono or di-(C.sub.1 -C.sub.4)alkylamino (C.sub.1 -C.sub.4)alkyl (meth)acrylamide, and, optionally, an associative monomer.
摘要:
The invention relates to the stabilization of mixtures of proteolytic and lipolytic enzymes in a liquid medium such as a liquid detergent composition. By inclusion therein of a stabilizing system comprising a polyol and a boron compound which are capable of reacting with each other whereby the polyol has a first binding constant with the boron compound of at least 500 l/mole and a second binding constant of at least 1,000 l.sup.2 /mole.sup.2, the stability of the lipase in the presence of the protease is significantly improved.The lipase is preferably obtained from Humicola lanuginosa, and the stabilizing system preferably comprises a mixture of sorbitol and borax.
摘要:
This invention provides a liquid detergent composition comprising:(a) 5-85% by weight of a surfactant selected from the group consisting of anionic, nonionic, cationic, ampholytic or zwitterionic surfactants and mixtures thereof;(b) an effective amount of enzyme; and(c) an amount of protein containing quaternary nitrogen substituent sufficient to stabilize the enzyme from loss of activity.
