Abstract
This disclosure relates to a composition comprising a continuous hydrophobic phase, a hydrophilic phase dispersed in the hydrophobic phase, a hydrophilic active ingredient dissolved in the hydrophilic phase, and a stabilizing component comprising 4-20 wt % or 4-7.9 wt % of an emulsifier having a hydrophilic-lipophilic balance (HLB) value of at least 10, and 80-96 wt % or 92.1-96 wt % of an emulsifier having an HLB value of less than 10, wherein the continuous hydrophobic phase optionally comprises a solid lipid component comprising 50-100 wt % of one or more high melting point triglycerides and 0-50 wt % of one or more waxes and optionally wherein the weight ratio of the stabilizing component to the hydrophilic active ingredient is less than 10:1.
