PERSONAL CARE COMPOSITIONS COMPRISING A SENSATE
A personal care composition comprising a sensate comprising a methyl ketone structure with fewer than two rings. In one embodiment this sensate is selected from the group consisting of gamma methyl ionone; 6-Methyl-5-hepten-2-one; and mixtures thereof.
1 ) A method of treating skin comprising:
a) applying a personal care composition to a portion of skin to form a portion of treated skin, said personal care composition comprising from about 0.001% to about 20% of a sensate having a methyl ketone structure with fewer than two rings.
2 ) The method of claim 1 , wherein said step of applying said personal care composition forms a minimum dosage level of at least 0.0015 mg/cm 2 of said sensate.
3 ) The method of claim 1 , further comprising a step of leaving said personal care composition on said portion of treated skin for from about 5 seconds to 120 seconds.
4 ) The method of claim 1 , further comprising a step of removing said personal care composition from said portion of treated skin, followed by applying a second personal care composition also comprising a sensate having a methyl ketone structure with fewer than two rings.
5 ) The method of claim 1 , wherein said portion of skin is from at least one of the following body parts: the lips, the face, the neck, the underarm, the upper and/or fore arm, the chest, the back, the loin, the leg, the thigh, the abdomen and a mixture thereof.
6 ) The method of claim 1 , wherein the sensate having a methyl ketone structure with fewer than two rings is selected from the group consisting of gamma methyl ionone; 6-Methyl-5-hepten-2-one; and mixtures thereof.
7 ) The method of claim 6 , wherein said gamma methyl ionone has the formula of:
8 ) The method of claim 6 , wherein the 6-Methyl-5-hepten-2-one has the formula of:
9 ) The method of claim 1 , further comprising a step of down regulating at least on TRP receptor in the proximity of said portion of treated skin, wherein said at least one TRP receptor is selected from the group consisting of a TRPV1 receptor, a TRPA1 receptor, and a combination thereof.
10 ) The method of claim 9 , wherein both the TRPV1 receptor and the TRPA1 receptors are down regulated.
11 ) The method of claim 1 , further comprising a step of at least partially removing hair from said portion of skin prior to the step of applying the personal care composition.
12 ) The method of claim 1 , further comprising a step of at least partially removing hair from said portion of treated skin after to the step of applying the personal care composition.
13 ) The method of claim 1 , wherein the personal care composition is selected from the group consisting of cosmetics, moisturizers, lotions, oils, personal cleansers, facial cleansers, shave gels, shave foams, shave oils, after shaves lotions and splashes, pre-shave lotions or oils, and combinations thereof.
14 ) The method of claim 1 , wherein the personal care composition further comprises an additional sensate selected from the group consisting of: 1-(1,2,3,4,5,6,7,8-octahydro-2,3,8,8-tetramethyl-2naphthalenyl)-ethan-1-one molecule; p-methane-3,8-diol; Isopulegol; Menthoxypropane-1,2,-diol; Curcumin; Menthyl Lactate; Gingerol; Icilin; Menthol; Tea Tree Oil; Methyl Salicylate; Camphor; Peppermint Oil; N-Ethyl-p-menthane-3-carboxamide; Ethyl 3-(p-menthane-3-carboxamido)acetate; 2-Isopropyl-N,2,3-trimethylbutyramide; Menthone glycerol ketal, and mixtures thereof.
15 ) A personal care composition comprising:
a) from about 0.001% to about 1% of a sensate selected from the group consisting of gamma methyl ionone; 6-Methyl-5-hepten-2-one; and mixtures thereof; and
b) from about 50% to about 99.99% of a carrier selected from the group consisting of: a oil-in-water emulsion, water in oil emulsion, a water-in-silicone emulsion, an silicone-in-water emulsion, a lathering surfactant aqueous solution, and mixtures thereof.
