AS ADMINISTRATIVE AGENT 2016-04-20 Assigned to CALUMET PENRECO, LLC reassignment CALUMET PENRECO, LLC RELEASE BY SECURED PARTY (SEE DOCUMENT FOR DETAILS). Clear rigid gels are desirable products in the cosmetic and personal care industry. While there are many prior art methods to make clear aqueous gels, there are few methods of making clear non-aqueous gel compositions. Aqueous gels are clear and strong, but they dry out and crack as the aqueous component volatilizes. Prior art clear non-aqueous gels are often very soft, and they exhibit such undesirable properties as synerisis and haziness.

The prior art non-aqueous gels that are clear and rigid, such as gels made with Versagel® R for cosmetic use, exhibit high elasticity and low “pay-off” (a term used to describe both the amount of product, such as lipstick, and the way the product distributes on the user's skin). These qualities make all prior art non-aqueous gels known to the present inventor inadequate where a non-aqueous gel is desired that possesses the qualities of clarity, rigidity, non-elasticity, and high pay-off. 6,468,510 teaches a transparent lipstick composition comprising an N-acyl glutamic acid diamide (sold by Ajinomoto Co., Inc., under the trade designation GP-1) as an oil-gelatinizing agent. However, the present invention combines GP-1 with an ester compound (C12-C15 alkyl benzoate) to give a much stiffer consistency than with the combinations disclosed in the prior art. In the present invention, the combination of GP-1 and Versagel S1000 also helps to constitute crystallinity to the otherwise rubbery texture of Versagel S1000 alone.

Traditionally, lipsticks have been made out of wax, oil, castor oil and a colored pigment blend. In recent years, the industry trend has been to create long-lasting lipsticks with large volumes of volatile silicone to create a thin film on the lips.

The disadvantage of this technology is that the film usually becomes dry and cracked due to the escape of the volatile components. Large amounts of wax in the formulation will also make the lipstick brittle and difficult to apply, and it will negatively affect the gloss quality. Versagel® S1000 can be used to replace a portion of the wax and silicone components in a traditional lipstick formula to improve the moisturization, film formation, and texture of the finished products.BRIEF SUMMARY OF THE INVENTION. Versagel S1000 comprises approximately 80% by weight hydrogenated polyisobutene, 6% by weight butyl stearate, 6% by weight isostearyl alcohol, 1.5% by weight hydrogenated styrene/isoprene copolymers, 5% by weight. Kraton G1650® polymers, 1% by weight dibutyl lauroyl glutamide, and 0.07% by weight butylated hydroxy toluene. To make the base component of Versagel® S1000, hydrogenated polyisobutene is placed in a mixing vessel along with butylated hydroxy toluene and hydrogenated polyisobutene which is then heated to 75 C while stirring. Both polymers and dibutyl lauroyl glutamide are added to the mixture which is brought up to a range of 120-135 C, until the solids are dissolved.

The temperature is then lowered and all subsequent ingredients are mixed into the composition to make the base product. The Versagel® S1000 is then used along with hydrogenated polyisobutene, C 12-15 Alkyl Benzoate, and dibutyl lauroyl glutamide to produce a clear or semi-clear non-aqueous gel that can be used to form a rigid lipstick with low elasticity and high pay-off.
