ABSTRACT:
A clear liquid synthetic organic heavy duty laundry detergent composition for use with an oxidizing bleach such as chlorine bleaches comprising a non-ionic and anionic biodegradable synthetic organic detergent system, water, an alcohol and at least one oxidizing bleach stable brightening agent selected from 4,4'-Bis(4-phenyl-1,2,3-triazol-2-yl)-2,2'stilbene disulfonic acid and salts thereof, 4,4'-diphenylvinylene-2,2'biphenyl disulfonic acid, and salts thereof. Small proportions of various additional optional agents such as sequestering agents and saltforming bases may also be included in the composition which is a single phase clear stable liquid which can be made opaque, creamy or opalescent if desired. The composition furthermore is substantially neutral or only slightly alkaline when measured at a 1% concentration in water and cleans and brightens soiled laundry to a degree comparable to that utilizing phosphate built alkaline detergents. Furthermore, by a judicious choice of non-ionic biodegradable detergents, the liquid detergent composition may be made to be non-gelling on standing in contact with the atmosphere.
