Abstract
Abstract A composition comprising the product of a homogeneous dispersion of water and the active components soap, a water-soluble alkali-metal silicate, and sulfonated castor oil and having a pH adjusted with acid to within the range of 6.5 to 10 for applying to the hands or other parts of the body to protect the skin against the aid in removal of non-water-soluble contaminants or soil.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
105 words
A stable, spreadable composition for application to the skin, particularly of the hands, for protecting against and aiding removal of contaminants, comprising: the homogeneous product of dispersing in water the active components comprising soap particles, sulfonated castor oil, and a water-soluble alkali-metal silicate, the amount of said silicate being sufficient to provide the theoretical silica equivalent of between about 8 and 60 weight percent of the weight of sulfonated castor oil and the amount of sulfonated castor oil being between about 30 and 130 weight percent of the weight of soap, and acid as needed to adjust the pH to between about 6.5 and 10.
Claim 2
Dependent Claim
