Abstract
A process for the production of a solid cosmetic preparation is described wherein a wax phase comprising at least one wax, at least one oil, and if applicable, oil-soluble ingredients and solvents are melted, the molten wax phase is mixed with an aqueous phase comprising at least one water-soluble or water-soluble water-dispersible film former and with a w/o emulsifying system until an emulsion is formed, and the resulting emulsion is allowed to cool to form a wax matrix with aqueous phase droplets embedded therein, and the products made therefrom and their use.
Claims2
A wax preparation, comprising:
- a continuous wax phase comprising at least one wax;
- and
- 2%-10% of a volatile silicone oil;
- and
- 1%-10% of a water-in-oil emulsifying system,
- wherein the water-in-oil emulsifying system comprises:
- a sucrose ester-based emulsifier selected from the group consisting of sucrose laurate, sucrose stearate, sucrose distearate, sucrose polystearate, and combinations thereof, and
- a polyglyceryl fatty acid ester-based emulsifier selected from the group consisting of a polyglyceryl-5 dioleate, polyglyceryl-10 diisostearate, polyglyceryl-6 distearate, and combinations thereof;
- and
- a discontinuous aqueous phase comprising water and 8%-25% film former, wherein the film former is a mixture of polyurethane 35 and styrene/acrylates/ammonium methacrylate copolymer.
A pencil lead for a pencil, comprising:
- a solid-form preparation, wherein the solid-form preparation comprises
- a continuous wax phase comprising at least one wax;
- and
- 2%-10% of a volatile silicone oil;
- and
- 1%-10% of a water-in-oil emulsifying system,
- wherein the water-in-oil emulsifying system comprises:
- a sucrose ester-based emulsifier selected from the group consisting of sucrose laurate, sucrose stearate, sucrose distearate, sucrose polystearate, and combinations thereof, and
- a polyglyceryl fatty acid ester-based emulsifier selected from the group consisting of a polyglyceryl-5 dioleate, polyglyceryl-10 diisostearate, polyglyceryl-6 distearate, and combinations thereof;
- and
- a discontinuous aqueous phase comprising water and 8%-25% film former, wherein the film former is a mixture of polyurethane 35 and styrene/acrylates/ammonium methacrylate copolymer.
