0.01-95% particulates.
9 . The composition of claim 8 further comprising one or more sunscreens.
10 . The composition of claim 9 having an SPF ranging from about 1 to 25.
11 . A method for moisturizing and hydrating lips comprising applying to the lips a lipstick composition comprising water and at least one occlusive oil capable of forming a barrier layer on the lips after the lipstick composition has been applied to the lips.
12 . The method of claim 11 wherein the at least one occlusive oil forms a water entrapping barrier layer on the lips.
13 . The method of claim 12 wherein at least a portion of the water present in the lipstick is entrapped by the barrier layer.
14 . The method of claim 13 wherein the at least one occlusive oil forms an ingredient entrapping barrier layer on the lips.
15 . The method of claim 14 wherein the ingredients trapped by the barrier layer are oils, pigments, water soluble ingredients, or mixtures thereof.
16 . The method of claim 11 wherein the at least one occlusive oil is a phenyl-substituted silicone.
17 . The method of claim 16 wherein the phenyl-substituted silicone oil has a viscosity of greater than about 650 centipoise at 25° C.
18 . The method of claim 17 wherein the phenyl-substituted silicone oil has a viscosity of greater than about 850 centipoise at 25° C.
