TL;DR: A cosmetic composition comprising of 1-70% volatile solvent, 0.1-15% silicone resin, 10-45% wax, 5-50% powder, and 1-30% oil has improved transfer resistance over previously-known cosmetics as discussed by the authors.
Abstract: A cosmetic composition comprising: a) 1-70% volatile solvent; b) 0.1-15% silicone resin; c) 10-45% wax; d) 5-50% powder; and e) 1-30% oil has improved transfer resistance over previously-known cosmetics. They may be prepared by grinding some of the dry components with the solvent and resin, adding the wax and oil followed by the remainder of the dry components. When filled into suitable receptacles, the composition may be used as a concealer, blusher, eye shadow, foundation, lipstick or the like.
TL;DR: In this paper, a lipstick composition consisting of wax, emollient and a gelling agent is described. And a method of making the lipstick is also disclosed, which can be delivered to the lips in a non-polar/lipophilic medium in a thermodynamically stable way.
Abstract: The present invention relates to lipstick compositions which comprise wax, emollient and a gelling agent wherein the inclusion of the gelling agent facilitates the retention of emollient oils particularly under high humidity and temperatures. Lipsticks of the present invention contain moisturizers which may be delivered to the lips in a non-polar/lipophilic medium in a thermodynamically stable way by using associated structures. A method of making the lipstick is also disclosed.
TL;DR: In this article, a gloss-enhancing amount of isohexadecane in a conventional lipstick formulation was revealed, i.e. about 0.5 to 8 weight percent of iso hexadecaine.

TL;DR: The D-optimal mixture design analysis showed that the variation in the response (melting point) could be depicted as a quadratic function of the main components of the lipstick.
Abstract: The D-optimal mixture experimental design was employed to optimize the melting point of natural lipstick based on pitaya (Hylocereus polyrhizus) seed oil. The influence of the main lipstick components-pitaya seed oil (10%-25% w/w), virgin coconut oil (25%-45% w/w), beeswax (5%-25% w/w), candelilla wax (1%-5% w/w) and carnauba wax (1%-5% w/w)-were investigated with respect to the melting point properties of the lipstick formulation. The D-optimal mixture experimental design was applied to optimize the properties of lipstick by focusing on the melting point with respect to the above influencing components. The D-optimal mixture design analysis showed that the variation in the response (melting point) could be depicted as a quadratic function of the main components of the lipstick. The best combination of each significant factor determined by the D-optimal mixture design was established to be pitaya seed oil (25% w/w), virgin coconut oil (37% w/w), beeswax (17% w/w), candelilla wax (2% w/w) and carnauba wax (2% w/w). With respect to these factors, the 46.0 °C melting point property was observed experimentally, similar to the theoretical prediction of 46.5 °C. Carnauba wax is the most influential factor on this response (melting point) with its function being with respect to heat endurance. The quadratic polynomial model sufficiently fit the experimental data.
TL;DR: In this article, a formulation comprising oils encapsulated in a water-soluble shell dispersed within an anhydrous base is presented, which imparts a shiny wet or moist look to the lips.
Abstract: Lipstick formulation comprising oils encapsulated in a water-soluble shell dispersed within an anhydrous base. The anhydrous base comprises a mixture of various waxes, oils and coloring agents. By remoistening the lips, a sustained release of the encapsulated oils is effected which imparts a shiny wet or moist look to the lips.
