Abstract
Methodologies and equipment for preparing a hypochlorite solution bleach consumer product to remove menstrual fluid, underarm perspiration or other hard-to-remove stains from soft fabric articles with reduced damage to the fabric articles when compared with popular chlorine bleaches. The soft fabric articles preferably are in white, although the present invention can also be applied to articles in other colors. In one embodiment, the weight concentration ratio of the alkali metal hydroxide over the hypochlorite salt in the hypochlorite admixture solution is no less than 1:12.5. The hypochlorite admixture solution may contain at least 0.2% by weight of sodium hydroxide and/or have a pH of at least 11.8.
Claims128
A method for producing a product that reduces the damaging effect of a bleach solution on a soft fabric article, comprising:
