Claims
- 1. A method of forming a film on the skin as a barrier to reduce transepidermal water loss comprising applying a conditioning formulation to the skin which is a polysiloxane copolymer dissolved in a cyclic siloxane, the copolymer having a viscosity of less than about 350 Centistokes, and having the formula ##STR4## in which x and y are integers each of which is equal to at least one, x has a value of ten or less, the sum of x and y is from sixty to one hundred, z is an integer having a value of five to seventeen, and R is an alkyl group having from one to thirty carbon atoms, the formulation including 5-10 percent by weight of the copolymer in the cyclic siloxane.
- 2. The method of claim 1 in which the copolymer includes forty mole percent of x units.
- 3. A film forming conditioning formulation for application to human skin comprising an effective amount of a polysiloxane copolymer dissolved in a cyclic siloxane, the copolymer having a viscosity of less than about 350 Centistokes, and having the formula ##STR5## in which x and y are integers each of which is equal to at least one, x has a value of ten or less, and is present in an amount of at least five mole per cent of the total repeating units, and y is present in an amount of units sufficient to provide improved spreading of the material when applied as a film on the skin, the sum of x and y is from sixty to one hundred, z is an integer having a value of five to seventeen, and R is an alkyl group having from one to thirty carbon atoms.
- 4. The formulation of claim 3 in which the formulation includes 5-10 percent by weight of the copolymer.
- 5. The formulation of claim 3 in which the copolymer includes forty mole percent of z units.
