AI Technical Summary

Benefits of technology

The present invention provides low-cost compositions that are anhydrous and have no oily component, which results in a reduced greasy feel relative to similar or identical compositions containing oil and / or water. These compositions dry faster and are more resistant to being washed off or rubbed off. Additionally, they provide a water-resistant or water-proof film, which prevents the undesired removal of actives upon exposure to moisture. This water resistance or water proofing is achieved, at least in part, by a silicone component included in the composition.

Problems solved by technology

In addition, the compositions may be made at room temperature which decreases the loss of certain actives during production.

Abstract

The present invention relates to compositions including anhydrous compositions which include a dimethicone crosspolymer and / or dimethicone elastomer gum and one or more skin care products.

Description

FIELD OF THE INVENTIONThe present invention relates to clear, greaseless compositions which include a pharmaceutically active component. The compositions are preferably anhydrous and include silicones, for example, one or more of dimethicone crosspolymers, dimethicone gum, hexamethyldisiloxane and low molecular weight dimethicones.More particularly, the composition may be a topically applied composition containing one or more analgesics or one or more skin care components.In a further and more specific aspect, the invention relates to clear, greaseless compositions including a pharmaceutically active component such as an analgesic including methyl salicylate, camphor, menthol and capsaicin or a skin care component selected from the group consisting of anti-wrinkle components, anti-skin atrophy components, skin repair components, and mixtures thereof. Advantageously, the pharmaceutically active component is a skin care component selected from the group consisting of retinoic acid, re...
