Abstract
Disclosed are hair styling compositions comprising at least two latex polymers chosen from acrylate and polyurethane polymers, wherein at least one latex polymer is a film-forming polymer. Methods of styling the hair are also disclosed.
Claims13
A method of styling the hair, said method comprising applying a composition to the hair, said composition comprising:
- (a) latex polymer A having a Young's modulus ranging from about 0.1 MPa to about 10 MPa, and a strain, under stress at 0.5 MPa, of at least about 1%, wherein latex polymer A is Acrylates copolymer, Acrylates/Ethylhexyl Acrylate copolymer, Acrylates/VA copolymer, Polyurethane-34, Polyurethane-32, or Polyurethane-48;
- and
- (b) latex polymer B having a Young's modulus ranging from about 10 MPa to about 6 GPa, and a strain, under stress at 0.5 MPa, of less than about 5%, wherein latex polymer B is Acrylates copolymer, Polyacrylate-2 crosspolymer, Styrene/Acrylic copolymer, Polyurethane-35, Polyurethane-1, or Polycarbamyl Polyglycol Ester;
- with the proviso that when latex polymer A is an acrylate polymer, latex polymer B is a polyurethane polymer;
- and when latex polymer A is a polyurethane polymer, latex polymer B is an acrylate polymer;
- wherein the total combined amount of latex polymers A and B ranges from about 0.1% to about 30% by weight, relative to the weight of the composition;
- wherein the weight ratio of latex polymers A:B ranges from about 10:1 to about 1:10;
- and
- wherein said composition is in a non-aerosol form chosen from a cream, a foam, a lotion, an emulsion, or a liquid.
