1. 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.
