Abstract

Cosmetic compositions are provided that include an extract from a seed of the Nicotiana species, one or more cosmetically acceptable carriers to act as a diluent, dispersant or carrier for the composition, and optionally one or more cosmetic adjuvants. The tobacco seed extract is typically characterized as having a significant lipid content and, thus, finds use as an oil component in a cosmetic composition.

First claim

What is claimed:

1. A method of forming a cosmetic composition, comprising:
receiving a crude oil that has been extracted from a seed of a plant of the Nicotiana species;
refining the crude oil through a chemical modification process comprising: treating the crude oil that has been extracted from a seed of the plant of the Nicotiana species with an acid to give an acid-treated oil; neutralizing the acid treated oil with a basic solution to give a neutralized mixture; and separating a precipitate from the neutralized mixture to provide the refined tobacco seed oil; and
incorporating the refined tobacco seed oil into a cosmetic composition comprising the refined tobacco seed oil and at least one cosmetically acceptable carrier, wherein the cosmetic composition is in a form adapted for application to skin or hair;
wherein the refined tobacco seed oil has a free fatty acid content of less than about 15 weight percent, based on the total weight of the refined tobacco seed oil.

2. The method of claim 1 , wherein the acid is citric acid.

3. The method of claim 1 , wherein the basic aqueous solution is sodium hydroxide.

4. The method of claim 1 , further comprising receiving a seed of the plant of the Nicotiana species and extracting the crude oil by dissolving the seed in a solvent suitable to extract the crude oil to form a solution and a residual solid seed material, separating the solution from the residual solid seed material, and concentrating the solution to provide an extracted or leached crude oil.

5. The method of claim 1 , wherein the refined tobacco seed oil has a free fatty acid content of less than about 10 weight percent, based on the total weight of the refined tobacco seed oil.

6. The method of claim 1 , wherein the refined tobacco seed oil comprises at least about 60 weight percent of linoleic acid, based on the total weight of the refined tobacco seed oil.

7. The method of claim 1 , wherein the cosmetic composition is in the form of an emulsion with an aqueous phase and an oily phase comprising the tobacco seed oil.

8. The method of claim 1 , wherein the cosmetically acceptable carrier is an aqueous carrier and the composition is in the form of an emulsion.

9. The method of claim 1 , wherein the cosmetic composition is in the form of a liquid, a lotion, a gel, a cream, a milk, an ointment, a paste, a plaster, a powder, a foam, a make-up, a stick, an aerosol, or embedded or absorbed in a wipe.

10. The method of claim 1 , wherein the cosmetic composition is adapted for use as a body moisturizing oil, a body moisturizing lotion, a body moisturizing gel, a body moisturizing cream, a shaving preparation, a skin powder, a suntan lotion, an anti-acne preparation, a peeling preparation, a shampoo, a hair conditioners, a hair tonic, a hair styling cream, a hair styling gel, a pomade, a hair rinse, a hair-straightening preparation, a hair-setting preparation, a hairspray, a hair dying or bleaching preparation, or a makeup.

11. The method of claim 1 , wherein the cosmetic composition further comprises one or more cosmetic adjuvants selected from the group consisting of additional fats or lipids, organic solvents, thickeners, binders, conditioning agents, demulcents, opacifiers, stabilizers, buffering agents, humectants, pigments, dyes, viscosity modifiers, emollients, antiperspirants, anti-foaming agents, foam boosters, hair colorants, hair perming agents, hair growth or restorer agents, hair loss prevention agents, abrasives, absorbents, anti-acne agents, anti-caking agents, moisturizing agents, perfumes or fragrances, preservatives, sunscreens, astringents, propellants, bleaching or lightening agents for skin or hair, tanning agents, deposition aids, suspending agents, polymers, fillers, sequestrants, bactericides, odor absorbers, antifungal agents, alkalinizing or acidifying agents, pearlescent aids, chelants, proteins, anti-dandruff agents, surfactants, emulsifiers, anti-free radical agents, antioxidants, vitamins, and α-hydroxy acids.

12. The method of claim 1 , wherein the cosmetically acceptable carrier comprises water and the cosmetic composition is in the form of a lotion or cream emulsion with an aqueous phase and an oily phase comprising a tobacco seed oil, the cosmetic composition further comprising one or more cosmetic adjuvants selected from the group consisting of additional oils, thickeners, surfactants, preservatives, pigments, humectants, emollients, occlusives, and combinations thereof.

13. The method of claim 1 , wherein the cosmetic composition further comprises one or more emollients in an amount of about 0.01 to about 20% by weight of the cosmetic composition.

14. The method of claim 1 , wherein the cosmetic composition further comprises one or more humectants in an amount of about 0.01 to about 10% by weight of the cosmetic composition.

15. The method of claim 1 , wherein the cosmetic composition further comprises one or more surfactants in an amount of about 0.01 to about 50% by weight of the cosmetic composition.

16. The method of claim 1 , wherein the cosmetic composition further comprises one or more conditioning agents in an amount of about 0.01 to about 5% by weight of the cosmetic composition.

17. The method of claim 1 , wherein the cosmetic composition further comprises one or more preservatives in an amount of about 0.01 to about 10% by weight of the cosmetic composition.

18. The method of claim 1 , wherein the cosmetic composition further comprises one or more thickening agents in an amount of about 0.01 to about 15% by weight of the cosmetic composition.

19. The method of claim 1 , wherein the cosmetic composition further comprises one or more emulsifiers in an amount of about 0.01 to about 15% by weight of the cosmetic composition.

20. The method of claim 1 , wherein the cosmetic composition further comprises one or more antioxidants in an amount of about 0.01 to about 10% by weight of the cosmetic composition.

21. The method of claim 1 , wherein the cosmetic composition further comprises one or more natural or essential oils in an amount of about 0.01 to about 20% by weight of the cosmetic composition.

22. The method of claim 1 , wherein the cosmetic composition further comprises one or more occlusives in an amount of about 0.01 to about 5% by weight of the cosmetic composition.

23. The method of claim 1 , wherein the cosmetic composition further comprises one or more agents useful for treating wrinkles in the skin in an amount of about 0.01 to about 5% by weight of the cosmetic composition.

24. The method of claim 1 , wherein the cosmetic composition is in the form of an emulsion adapted for moisturizing skin, the cosmetic composition comprising water in an amount up to about 80% by weight, the refined tobacco seed oil in an amount up to about 10% by weight, one or more emollients in an amount up to about 20% by weight, one or more emulsifiers in an amount up to about 15% by weight, and one or more humectants in an amount up to about 10% by weight.

25. The method of claim 1 , wherein the cosmetic composition is in the form of an emulsion adapted for cleansing skin or hair, the cosmetic composition comprising water in an amount up to about 80% by weight, the refined tobacco seed oil in an amount up to about 10% by weight, one or more emulsifiers in an amount up to about 15% by weight, and one or more surfactants in an amount up to about 50% by weight.
