摘要： Aqueous surfactant concentrates comprise water and about 30 to 80% by weight of a surfactant mixture of (a) at least 50% by weight anionic surfactants based on the weight of the surfactant mixture, including at least 20% alkyl benzene sulphonate based on the weight of the surfactant mixture, and (b) at least 2%, based on the weight of the surfactant mixture, of nonionic ethoxylate having an HLB less than 12, the water being present in an amount adapted to form a spherulitic or lamellar composition. Liquid detergents contain water, from 5 to 25% by weight of said surfactant mixture and enough dissolved electrolyte to form a non-sedimenting spherulitic composition.

摘要： A convenient method for preparing a stabilized aqueous enzyme dispersion comprises:

(1) precipitating a water-soluble polymer from aqueous solution to form an aqueous dispersion, and
(2) before, during or after (1), contacting the dissolved or dispersed polymer with an aqueous solution or fine aqueous dispersion of enzyme.

Using this method, substantial improvement of the enzyme stability during storage can be obtained with surprisingly little polymer (relative to enzyme). And enzyme stabilization can, surprisingly, even be obtained by contacting precipitated polymer with dissolved enzyme. The stabilizing effect therefore appears not to be due (or at least not primarily due) to encapsulation.
