Abstract
A clear, water based, homogeneous insect repellent sunscreen composition, comprising an oil soluble hydrophobic sunscreen component, an amido insect repellent component, an alcohol component, and water.
Claims22
A substantially emulsifier-free, clear, stable, single phase, water based, homogeneous insect repellent sunscreen composition, consisting essentially of:
- (a) about 1 weight % to about 45 weight % of a hydrophobic sunscreen component;
- (b) about 3 weight % to about 70 weight % of an amido insect repellent component;
- (c) about 10 weight % to about 60 weight % of at least one alcohol component having from 2 to 10 carbon atoms;
- and
- (d) 5 weight % to about 40 weight % of water, said components (b) and (c) being present in an amount sufficient to provide a clear homogeneous composition, and wherein the amido insect repellent component serves as a co-solvent with the low molecular weight alcohol component to enable the water component and the hydrophobic sunscreen component to be combined to produce the single phase, clear, stable, water based, homogeneous insect repellent sunscreen composition, said composition being substantially emulsifier-free, all percents being by weight of the total composition.
