Benefits of technology

The present invention provides an oil component made or derived from seeds of plants of the Nicotiana species that can be incorporated into various cosmetic products. The oil component has a high content of linoleic acid, which is beneficial for skin and hair. The oil can be in the form of a tobacco seed oil extract, which can be mixed with other cosmetic ingredients like fats, lipids, organic solvents, thickeners, binders, conditioning agents, and more. The resulting cosmetic compositions can be in the form of a lotion, cream, or body butter emulsion, among others. The oil component can also be combined with other ingredients like emollients, humectants, surfactants, preservatives, pigments, humectants, emollients, occlusives, antioxidants, vitamins, and α-hydroxy acids.

Problems solved by technology

However, these anti-aging acids can be associated with consumer discomfort characterized by burning, stinging, itching or a sensation of tightness after application.

example 1

[0105]The following non-limiting example describes how tobacco seed oil can be extracted and refined for purposes of the invention.

[0106]Tobacco seeds are harvested from field grown plants and extracted with hexane and agitation. The defatted seed cake is removed from the hexane extract by simple filtration. The extract is then placed in a distillation apparatus, which separates the hexane from the tobacco seed oil.

[0107]The raw oil derived from these processes comprises approximately 20% by weight free fatty acids, and 80% by weight triglyceride bound fatty acids, comprising primarily linoleic acid (˜70% by weight). The free fatty acids are then removed by a refinement process that consists of an acidic wash (citric acid) followed by a base wash (sodium hydroxide) and subsequent centrifugation. The resulting refined oil is approximately 4% by weight free fatty acids and 96% triglyceride bound fatty acids. A lower free fatty acid content is advantageous for product incorporation as ...

example 2

[0108]Storage and stability testing is performed on various embodiments of cosmetic products incorporating tobacco seed oil. The incorporation of the tobacco seed oil does not pose any unusual problems or issues when preparing formulations. The material is relatively easy to incorporate and is essentially comparable to Argan oil.

[0109]Stability testing (e.g., testing at 45° C., Freeze / thaw testing, testing at 4° C. and testing at room temperature) does not show any color or odor issues and no noticeable adverse effect on product integrity. Argan oil and tobacco seed oil behave in similar manners. The odor of the tobacco seed oil is very low and does not appear to go “rancid” or adversely affect the formulations prepared under stability test conditions.

[0110]In a Shampoo / Body Wash formula, the tobacco seed oil does not appear to have any adverse effect on foaming as compared to the Argan oil. From a practical use assessment, there does not appear to be any major formulation challenge...

example 3

[0111]As shown in Table 1, tobacco seed oil is incorporated into a facial moisturizer. The tobacco seed oil replaces sunflower seed oil, olive oil and grape seed oil in the product composition. The resulting product has sensory characteristics similar to the characteristics of a comparable composition containing the replaced ingredients.

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.

Description

FIELD OF THE INVENTION[0001]The present invention relates to cosmetic products comprising a components made or derived from tobacco. Of particular interest are oil compositions obtained or derived from plant seeds or portions of plant seeds from the Nicotiana species.BACKGROUND OF THE INVENTION[0002]Cosmetics are generally defined as substances used to enhance the appearance or odor of the human body. They are generally mixtures of chemical compounds, some being derived from natural sources and others being synthetic. In the U.S., the Food and Drug Administration (FDA), which regulates cosmetics, defines cosmetics as “intended to be applied to the human body for cleansing, beautifying, promoting attractiveness, or altering the appearance without affecting the body's structure or functions.”[0003]There are many different types of cosmetic products, including, but not limited to, hair treatment products such as shampoos and conditioners, body and facial cleansers, skin moisturizing pr...
