Problems solved by technology

[0003] Despite the known fact of using high (aqueous) internal phase emulsions, it is still difficult to form stable HIPE
Furthermore, the use of high water content emulsions, especially when the emulsion is a topically applied emulsion, does not achieve many of the desired sensory benefits of concern to consumers

Embodiment 1

[0075] A high humectant high internal phase emulsion according to the present invention is prepared by mixing the following ingredients:

[0076] Table I

[0077] Element wt% water margin glycerin 40-60 DC5225C 3 KSG340 2 KSG210 3 DC9045 5 DC245 9-12 DMF-A6 cs 1.5 CL2080 5 Aristoflex AVC 0-2

[0078] Add ingredients to mixing container. Combine water, thickener, and moisturizer in one container, and all other ingredients in another. The resulting mixtures were combined and mixed to form a homogeneous emulsion. Mixing was carried out at 25°C and atmospheric pressure.

[0079] The resulting compositions were evaluated for tack and pull or normal force. Viscosity and pull-up force were evaluated with an Ares Rheometer from TA Instruments. The temperature was maintained at 25°C. Pull-up force (Newtons) was determined with an initial gap set at 0.5 mm and a parallel geometry of 2.5 cm applied. All re...

Embodiment 2

[0084] Professional panelists applied high humectant HIPE similar to those prepared in Example 1 (approximately 2.5 mg composition / cm 2 skin). All panelists concluded that the HIPE prepared according to the invention was easy to apply, non-sticky and gave excellent wetting properties. The panelists also concluded that the HIPE of the present invention performed well (ie, produced skin moisturization) and was less tacky than a commercial formulation in which approximately 40 wt% glycerin was formulated.

Abstract

A high humectant high internal phase emulsion is described. The emulsion has a high content of humectant and less than about 70% by weight water in the internal phase. The emulsion yields excellent moisturizing results when applied and is not sticky during or after application.

Description

field of invention [0001] The present invention relates to high humectant high internal phase emulsions. More particularly, the present invention relates to high internal phase emulsions wherein the internal phase comprises at least about 70 volume percent of the emulsion and has less than about 70 weight percent water based on the total weight of the internal phase. High internal phase emulsions are excellent bases or carriers for topically applied actives. Unexpectedly, this emulsion is an excellent moisturizing composition that is easy to apply and has no unattractive sticky properties during or after application. Background of the invention [0002] A water-in-oil emulsion is a discontinuous or discrete dispersion of water particles, often referred to as an aqueous internal phase within an oil continuous or external oil phase. Certain emulsions can contain up to or above 70 vol% internal phase. Such emulsions are called high internal phase emulsions (HIPE). The volum...
