Abstract
A person's skin is protected from percutaneous absorption of lipophilic or semi-polar contaminant chemicals by applying to the skin a plural-constituent solvent system, wherein each constituent has a molecular weight greater than or equal to 350 and includes at least one solvent in which the contaminant chemicals are soluble. The solvent system may include one or more emulsifiers to facilitate water-rinsing of the solvent system and any dissolved contaminant chemicals from the skin. Oil-based and glycol-based solvent systems are disclosed, each having at least two solvents which may have different solubility ranges. The solvent system may be applied to the skin before exposure to contaminant chemicals to serve as a barrier or after exposure to serve as s cleanser. The solvent system includes no water, emollients or detergents and all constituents are skin-safe.
