COMPOSITIONS AND METHODS FOR DELIVERING CANNABINOIDS TO SKIN
Provided herein are compositions for delivering one or more cannabinoids to the skin of a subject and methods of using the compositions to deliver the one or more cannabinoids to the skin of a subject. The compositions contain a carrier that facilitates the delivery and permeation of cannabinoids to and through the skin. The carriers of the compositions contain squalane or mixtures of squalane and hemisqualane. The compositions described herein may serve as the base for the preparation of various cosmetics or various pharmaceuticals. The cosmetics or pharmaceuticals may be used to reduce inflammation, control pain, or prevent aging of the skin of a subject.
1 . A composition comprising a carrier and one or more cannabinoids, wherein the carrier comprises squalane.
2 . The composition of claim 1 , wherein the carrier further comprises hemisqualane.
3 . The composition of claim 2 , wherein the squalane and hemisqualane are present in a ratio from about 10 to 1 (squalane to hemisqualane) by weight to about 1 to 10 (squalane to hemisqualane) by weight.
4 . The composition of claim 3 , wherein the squalane and hemisqualane are present in a ratio of about 1 to 1 by weight.
5 . The composition of any one of the preceding claims, wherein the one or more cannabinoids comprises from about 0.01% w/w to about 10% w/w of the composition.
6 . The composition of claim 5 , wherein the one or more cannabinoids comprises from about 0.3% w/w to about 1% w/w of the composition.
7 . The composition of claim 6 , wherein the one or more cannabinoids comprises about 0.7% w/w of the composition.
8 . The composition of any one of the preceding claims, wherein the squalane comprises from about 10% w/w to about 99.9% w/w of the composition.
9 . The composition of any one of the preceding claims, wherein the one or more cannabinoids is selected from cannabidiol (CBD), cannabidiolic acid (CBDA), cannabinol (CBN), cannabigerol (CBG), cannabichromene (CBC), cannabicyclol (CBL), cannabivarin (CBV), tetrahydrocannabivarin (THCV), cannabidivarin (CBDV), cannabichromevarin (CBCV), cannabigerovarin (CBGV), cannabigerol monomethyl ether (CBGM), cannabielsoin (CBE), cannabicitran (CBT), tetrahydrocannabinol (THC), and tetrahydrocannabinolic acid (THCA).
10 . The composition of claim 9 , wherein the one or more cannabinoids comprises cannabidiol (CBD).
11 . A cosmetic comprising a carrier and a cannabinoid, wherein the carrier comprises squalane.
12 . The cosmetic of claim 11 further comprising one or more excipients selected from the group consisting of natural oils, synthetic oils, emulsifiers, emollients, lipids, humectants, moisturizers, binders, conditioning agents, emulsion stabilizing salts, preservatives, chelating agents, sequestering agents, abrasives, pH adjusters, surfactants, perfumes and colorings.
13 . The cosmetic of claim 11 or 12 , wherein the carrier further comprises hemisqualane.
14 . The cosmetic of any one of claims 11 - 13 , wherein the squalane and hemisqualane are present in a ratio of about 10 to 1 (squalane to hemisqualane) by weight to about 1 to 10 (squalane to hemisqualane) by weight.
15 . The cosmetic of any one of claims 11 - 14 , wherein the cannabinoid is selected from cannabidiol (CBD), cannabidiolic acid (CBDA), cannabinol (CBN), cannabigerol (CBG), cannabichromene (CBC), cannabicyclol (CBL), cannabivarin (CBV), tetrahydrocannabivarin (THCV), cannabidivarin (CBDV), cannabichromevarin (CBCV), cannabigerovarin (CBGV), cannabigerol monomethyl ether (CBGM), cannabielsoin (CBE), cannabicitran (CBT), tetrahydrocannabinol (THC), tetrahydrocannabinolic acid (THCA), and combinations thereof.
16 . The cosmetic of claim 15 , wherein the cannabinoid comprises cannabidiol (CBD).
17 . A method of delivering a cannabinoid to a subject comprising applying the composition of any one of claims 1 - 10 to a skin area of the subject.
18 . The method of claim 17 , wherein the composition is applied to the skin area in an amount of from about 0.1 mg/cm 2 to about 10 mg/cm 2 .
19 . The method of claim 18 , wherein the composition is applied to the skin area in an amount of from about 1 mg/cm 2 to about 3 mg/cm 2 .
20 . The method of any one of claims 17 - 19 , wherein an effective amount of cannabinoid is delivered to the subject.
21 . A method of reducing inflammation in skin of a subject comprising administering an effective amount of the composition of any one of claims 1 - 10 to the skin of the subject, thereby reducing inflammation.
22 . The method of claim 21 , wherein the composition is administered to the skin area in an amount of from about 0.1 mg/cm 2 to about 10 mg/cm 2 .
23 . The method of claim 22 , wherein the composition is administered to the skin area in an amount of from about 1 mg/cm 2 to about 3 mg/cm 2 .
24 . The method of any one of claims 21 - 23 , wherein the composition is administered at least daily.
25 . The method of claim 24 , wherein the composition is adminstered at least twice daily.
26 . A method of reducing pain in a subject comprising administering an effective amount of the composition of any one of claims 1 - 10 to the skin of the subject, thereby reducing pain.
27 . The method of claim 26 , wherein the composition is administered to the skin area in an amount of from about 0.1 mg/cm 2 to about 10 mg/cm 2 .
28 . The method of claim 27 , wherein the composition is administered to the skin area in an amount of from about 1 mg/cm 2 to about 3 mg/cm 2 .
29 . The method of any one of claims 26 - 28 , wherein the composition is administered at least daily.
30 . The method of claim 29 , wherein the composition is adminstered at least twice daily.
