Claims4
A gel composition comprising:
- a silicone elastomer from the reaction of;
- A) an SiH containing MQ resin comprising the formula
- (Me2HSiO1/2)a(Me3SiO1/2)b(SiO4/2)e
- where
- a is greater than 0
- b is from 0 to 0.8
- e is 0 to 0.9,
- with the provisos that the sum of a, b, and e is at least 0.95 and e is greater than 0,
- Me is methyl,
- B) an organic compound having at least two aliphatic unsaturated groups in its molecule selected from
- H2C═CHCH2O[C3H6O]gCH2CH═CH2,
- H2C═CHO[C3H6O]gCH═CH2,
- HC≡CCH3O[C3H6O]gCH2C≡CH2
- HC≡CC(CH3)2O[C3H6O]gC(CH3)2C≡CH, or
- H2C═C(CH3)CH2O[C3H6O]gCH2C(CH3)═CH2,
- where g is greater than 2,
- and
- C) a hydrosilylation catalyst,
- and;
- D) a carrier fluid selected from isododecane, isohexyldecane, or isodecyl neopentanoate,
- E) an optional personal or healthcare active,
- wherein the gel composition has a hardness of at least 0.03 Newton force.
