MQ-T propyl siloxane resins comprising (R13SiO112)a, (R22SiO2/2)b , (R3SiO3/2)c , and (SiO4J2)d units, where at least 40 mole % of the R3 groups are propyl are disclosed. A method of preparing such siloxane resins by reacting a MQ siloxane resin with a T propyl siloxane resin is also disclosed. These siloxane resins are useful in a variety of personal, household, and medical care applications, and in particular, as a resin additive in pigmented cosmetic formulations. |
