Abstract
A harshness reducing, enzymatic additive for a main wash detergent based on a fungal cellulase, i.e., a cellulase produced by means of Humicola insolens. The enzymatic additive can be produced in high yields and has an extraordinarily high activity at alkaline pH values, whereby it is possible to mix the additive with a main wash detergent and perform the harshness reduction and the washing as a single operation.
Claims14
A harshness reducing detergent additive for a main wash detergent composition, comprising
- a non-dusting granulate containing a fungal cellulase producible by a strain of Humicola insolens or Humicola grisea var. thermoidea.
A harshness reducing detergent additive for a main wash detergent composition, comprising
- a solution of a fungal cellulase producible by a strain of Humicola insolens or Humicola grisea var. thermoidea, and a non-ionic surfactant.
A main wash detergent composition, which comprises detergent ingredients and a harshness reducing amount of a fungal cellulase producible by a strain of Humicola insolens or Humicola grisea var. thermoidea, said composition having a pH in a solution of 1 g of the main wash detergent composition in 1 liter of 10.degree. German water in the range of from 7 to 10.
A main wash method which comprises:
- washing cellulose containing textiles, at less than 70.degree. C. with a main wash detergent composition having therein a proteolytic enzyme and a harshness reducing agent at a pH in the range of pH 7-10, said harshness reducing agent being a fungal cellulase producible by a strain of Humicola insolens (Humicola grisea var. thermoidea) and being present in a content of from 5 to 50 regular C.sub.x units/gram of detergent composition.
