The process is comprised of dispersing one or more polyacrylic acid polymers in water to form a dispersion; melting one or more fatty alcohols and at least one wax and/or a mixture of liquid and solid hydrocarbons to form a mixture; thoroughly mixing the dispersion and mixture obtained in (a) and (b) without effecting complete homogenization, incomplete homogenization causing the graininess of the preparation; and optionally, adding one or more substances selected from neutralizing agents, skin moisturizers, preservatives, oils, thickeners and perfumes.
