  • Patent number: 10292925
    Abstract: The present invention relates to a PEG free, stable, low viscosity classic oil-in-water emulsion and the use and preparation thereof. The oil-in-water emulsion comprises, A) a primary emulsifier selected from alkyl polyglucosides and long chained polyglycerol esters, B) a secondary emulsifier selected from short chained polyglycerol esters and short chained sorbitan esters, and optionally a thickener if the amount of secondary emulsifier is below 2.5 wt. %. The emulsion is a classic emulsion and can be sprayable. The emulsion is suitable to prepare spray or foam emulsion products with good application effect.

  • Patent number: 9675533
    Abstract: A changing color composition in the form of a gel for caring for and/or making up keratin materials is disclosed. The composition comprises in a physiologically acceptable medium, a) from 0.1 to 10% by weight preferably from 0.5 to 10% more preferably from 1 to 5% by weight relative to the weight of the composition of microcapsules containing releasable colorant(s), said microcapsules comprising: —a core comprising one organic material, —at least one layered coating surrounding said core, the layered coating comprising at least one polymer at least one colorant, and advantageously at least one lipid-based material, b) at least 3% by weight, preferably at least 5% by weight, more preferably at least 8% by weight and advantageously at least 10% by weight relative to the weight of the composition of an aqueous phase comprising water and at least one compound chosen from polyols, glycols and C2-C8 monoalcohols, and mixtures thereof, and c) at least one hydrophilic gelifying agent.
