Abstract
A film-forming composition comprises a stable aqueous solution of a protein hydrolysate, e.g. a partially hydrolyzed collagen protein, preferably having a molecular weight of from 3,000 to 45,000, glycerol and optionally a water-miscible solvent. The composition may be used to form a protective barrier on skin, e.g. one or more teats of a cow.
Claims5
A non-gelling, film-forming composition comprising a stable aqueous solution containing 25% to 40% by weight of partially hydrolysed collagen protein solids having a molecular weight of from 3,000 to 45,000 and from 1% to 10% by weight glycerol.
A method of treating human or animal skin comprising applying a coating of a non-gelling, film-forming composition comprising a stable aqueous solution containing 25% to 40% by weight of partially hydrolysed collagen protein solids having a molecular weight of from 3,000 to 45,000 and from 1% to 10% by weight glycerol to said skin, and effecting drying of said coating to form a film.
A method of forming a protective barrier film around one or more teats of a cow comprising applying a coating of a non-gelling, film-forming composition comprising a stable aqueous solution containing 25% to 40% by weight of partially hydrolysed collagen protein solids having a molecular weight of from 3,000 to 45,000 and from 1% to 10% by weight glycerol to said teat(s) and effecting drying of said coating to form said protective barrier film.
