Abstract
Abstract A solid, non-thixotropic pre-wash cleaner is disclosed. Its ingredients are a balanced system of selected paraffinic hydrocarbon solvents and nonionic synthetic detergents, tallow soap and sorbitol. The sorbitol binds the composition into a solid mass suitable for forming into a soap stick. Sodium thiosulfate, perfume and color are optional ingredients and may be added for preservation and aesthetic enhancement.
