Patent ID: 7887785

Claim:
A personal care composition comprising a formulation including a silicone resin of the generic formula: MQ, wherein the ratio of M to Q is about from 0.01/1 to about 3.96/1; M x D y T z , wherein x is about 0.01 to about 3,900,000, y is about 0.035 to about 10,000,000, z is about 0.35 to about 8,000,000; TD, wherein the ratio of T to D is about 0.001/1 to about 73/1; or a combination comprising at least one of the foregoing resins, wherein the formulation includes a sunscreening agent and has an SPF, wherein the resin or resin combination is present in an amount effective to increase the SPF of the formulation at least about 10% over the same formulation without the resin or resin combination; and further wherein M is of the formula R 1 a R 2 b R 3 c SiO 1/2 wherein each R 1 and R 2 is independently the same or different monovalent hydrocarbon radical having 1 to about 60 carbon atoms, a hydroxyl, or a halogen; R 3 is a hydroxyl, a halogen, or a monovalent hydrocarbon radical having 1 to about 90 carbon atoms, optionally with a heteroatom; and a=1, 2, or 3; b=0, 1, or 2; c=0, 1, or 2; subject to the limitation that a+b+c=3; Q is of the generic formula SiO 4/2 ; T is of the formula R 4 SiO 3/2 wherein each R 4 is independently a hydroxyl, a halogen, or a monovalent hydrocarbon radical having 1 to about 60 carbon atoms, optionally with heteroatoms; D is of the formula R 5 R 6 SiO 2/2 , wherein each R 5 and R 6 is independently a hydroxyl, a halogen, or a monovalent hydrocarbon radical having 1 to about 60 carbon atoms, optionally with heteroatoms; a personal care component; and a volatile fluid, said composition achieving an increase in SPF value as compared to the SPF value of a composition without said silicone resin, wherein the ratio of increase of the SPF value to the weight percent of said silicone resin in the composition (% SPF increase/wt. % silicone), is from 12 to 36.
