In one preferred embodiment, the topical ointment comprises a particulate material such as zinc oxide as an optional component.
1. A topical ointment comprising from about 30% by total weight of the ointment to about 80% by total weight of the ointment of an emollient, from about 20% by total weight of the ointment to about 40% by total weight of the ointment of a structurant, from about 0.1% by total weight of the ointment to about 40% by total weight of the ointment of a rheology enhancer, from about 0.1% by total weight of the ointment to about 10% by total weight of the ointment of a surfactant having an HLB in the range of from about 2 to about 7, wherein the rheology enhancer is selected from the group consisting of polyisobutylene; hydrogenated polyisobutene and butylene/ethylene/styrene copolymers; hydrogenated polyisobutene and ethylene/propylene/styrene copolymers and butylene/ethylene/styrene copolymers; isononyl isononanoate and ethylene/propylene/styrene copolymers and butylene/ethylene/styrene copolymers; isododecane and ethylene/propylene/styrene copolymers and butylene/ethylene/styrene copolymers; isohexadecane and ethylene/propylene/styrene copolymers and butylene/ethylene/styrene copolymers; isopropyl palmitate and ethylene/propylene/styrene copolymers and butylene/ethylene/styrene copolymers; and combinations thereof.
2. The topical ointment as set forth in claim 1 wherein the surfactant is selected from the group consisting of sorbitan monooleate, sorbitan sequioleate, sorbitan trioleate, glyceryl stearate, sorbitan stearate, sorbitan tristearate, and mixtures thereof.
3. The topical ointment as set forth in claim 1 further comprising from about 0.1% by total weight of the ointment to about 10% by total weight of the ointment of a hydrophilic skin care active.
4. The topical ointment as set forth in claim 3 wherein the hydrophilic skin care active is selected from the group consisting of botanicals, glycerin, hydrogenated starch hydrolysate, propylene glycol, sodium PCA, sodium lactate, sorbitol, and mixtures thereof.
5. A topical ointment comprising from about 30% by total weight of the ointment to about 80% by total weight of the ointment of an emollient, from about 20% by total weight of the ointment to about 40% by total weight of the ointment of a structurant, from about 0.1% by total weight of the ointment to about 40% by total weight of the ointment of a rheology enhancer, from about 0.1% by total weight of the ointment to about 10% by total weight of the ointment of a particulate material, and from about 0.1% by total weight of the ointment to about 10% by total weight of the ointment of a low HLB surfactant, wherein the rheology enhancer is selected from the group consisting of polyisobutylene; hydrogenated polyisobutene and butylene/ethylene/styrene copolymers; hydrogenated polyisobutene and ethylene/propylene/styrene copolymers and butylene/ethylene/styrene copolymers; isononyl isononanoate and ethylene/propylene/styrene copolymers and butylene/ethylene/styrene copolymers; isododecane and ethylene/propylene/styrene copolymers and butylene/ethylene/styrene copolymers; isohexadecane and ethylene/propylene/styrene copolymers and butylene/ethylene/styrene copolymers; isopropyl palmitate and ethylene/propylene/styrene copolymers and butylene/ethylene/styrene copolymers; and combinations thereof.
6. The topical ointment as set forth in claim 5 wherein the rheology enhancer is polyisobutylene.
