Abstract:
1. Process for making a wet-skin treatment composition comprising the steps of: i) forming an aqueous phase comprising less than 1% anionic surfactant, water and dispersion stabilizer, wherein said dispersion stabilizer is selected from inorganic dispersion stabilizers selected from clays, silicas and mixtures thereof; organic stabilizers having a molecular weight lower than about 1000 Daltons and capable of forming a network in the aqueous phase that immobilizes a dispersed structured oil phase and wherein said organic stabilizer is selected from the group consisting glycol mono-, di- and triesters having 14 to 22 atoms carbon alone and mixtures thereof; and polymeric stabilizers selected from carbohydrate gums, acrylate-containing homo and co-polymers and mixtures thereof, ii) forming a structured oil phase comprising a liquid oil selected from triglycerides, modified triglycerides, or their mixtures and a structurant present in an amount to yield viscosity of 100 to 5000 poise measured at 1 sec iii) directly mixing said structured oil phase and said aqueous phase to form a structured oil-in-water predispersion having weight average droplet size of greater than about 100 microns; iv) passing said structured oil-in-water predispersion through a screen having an opening of up to about 2000 micrometers to make the wet skin treatment composition having oil drops of about 20 to 300 microns in size;
