Abstract
Bleaching and cleaning compositions having improved bleaching and cleaning capacity are disclosed which comprise a peroxide compound bleach, e.g. sodium perborate, a proteolytic enzyme and manganese (II) metal. The bleaching and cleaning compositions are effective for washing fabrics at substantially all washing temperatures, and are usable for example in washing machines at lower than 60.degree. C. wash cycle.
Claims10
A bleaching and cleaning composition having improved bleaching and cleaning capacity at all washing temperatures, especially at lower temperatures, comprising:
- (a) from 4 to 90% by weight of a peroxide compound bleach;
- (b) from 0.001 to 10% by weight of a proteolytic enzyme;
- and
- (c) a manganese compound which yields manganese (II) cations in aqueous solution in an amount of from 0.005 to 5% by weight as manganese (II) metal ion based on the total composition.
An alkaline bleaching and cleaning agent having improved bleaching and cleaning capacity at all washing temperatures and especially at lower temperatures, comprising:
- (i) from 2 to 50% by weight of a detergent-active material, selected from the group consisting of organic anionic, nonionic, amphoteric and zwitterionic detergents and soaps, and mixtures thereof;
- (ii) from 15 to 60% by weight of a detergency builder salt;
- (iii) from 4 to 35% by weight of a peroxide compound bleach;
- (iv) from 0.001 to 10% by weight of a proteolytic enzyme;
- and
- (v) from 0.005 to 5% by weight of manganese (II) metal ion.
- such that the composition has a solution pH of from 8-13 and a proteolytic activity of from 2 to 20 Anson Units per kilogram.
