Abstract
This invention provides for a thin emulsion base for cosmetic products with low to medium viscosity. The bases are excipients that provide stability to cosmetic products. The thin emulsion bases of this invention are from non-synthetic and non-petroleum based products and comprise over 80% juice derived solvents with the balance being a combination of alkane texture enhancers and lipid emulsifiers.
Claims17
A composition comprising a thin emulsion base and an active ingredient, wherein the thin emulsion base comprises a solvent, an alkane texture enhancer, and a lipid emulsifier, wherein:
- i) the solvent is a plant juice derived supernatant having 6-20 wt % carbohydrate content, an acidic pH of between 2.2 to 6.0, and a bacterial cell count of less than 150 CFU/g, wherein the amount of the solvent ranges from 85 to 86 wt % of the total weight of the thin emulsion base;
- ii) the alkane texture enhancer is a mixture consisting of at least 90 wt % C12 alkanes, less than 10 wt % C14 alkanes, and less than 10 wt % coco-caprylate/caprate;
- iii) the lipid emulsifier is a mixture consisting of 30 to 60 wt % polyglyceryl-10 mono/dioleate, 30 to 60 wt % polyglyceryl-3 oleate, 3 to 7 wt % glycerin, and 0.5 to 1.5 wt % phosphatidylglycerol;
- wherein the weight to weight ratio of the alkane texture enhancer to the lipid emulsifier of the thin emulsion base is 1;
- and
- wherein the thin emulsion base is stable for at least 90 days at 40° C.
