67 words
A skin treatment composition which counteracts moisture loss and promotes healing of burned or sunburned skin, in the form of an ointment, cream, lotion or liquid, comprising water, at least one preservative and between about 2% and about 30% by weight of a moisturizing component which is comprised of polyglyceryl methacrylate, glycerine, allantoin, panthenol, fibronectin and an amino acid complex including proline, arginine, and pyrrolidone carboxylic acid.
Claim 2
Dependent Claim
67 words
A skin treatment composition which counteracts moisture loss and promotes healing of burned or sunburned skin, in the form of an ointment, cream, lotion or liquid, comprising water, at least one preservative and between about 2% and about 30% by weight of a moisturizing component which is comprised of polyglyceryl methacrylate, glycerine, allantoin, panthenol, fibronectin and an amino acid complex including proline, arginine, and pyrrolidone carboxylic acid.
Claim 3
Dependent Claim
31 words
The composition as defined in claim 1 wherein the moisturizing component is present in an amount within the range of from about 5 to about 15% by weight of the composition.
Claim 4
Dependent Claim
21 words
