Method of making an anhydrous, pigmented composition |
| 摘要 |
The invention relates to a method of making an anhydrous, pigmented sunscreen composition. The method comprises first adding a hydrophobic silica to a lipid phase comprising a dispersed color pigment and an organic UV-filter and homogenizing the mixture. Next, a hydrophilic silica is added and re-homogenization is performed. |

1. A method of making an anhydrous, pigmented sunscreen composition, comprising in sequence:
adding a hydrophobic silica to a lipid phase comprising a dispersed color pigment and an organic UV-filter; homogenizing the lipid phase comprising the hydrophobic silica by rotary mixing at a rotation speed of at least 1000 rpm; adding a hydrophilic silica to the lipid phase comprising hydrophobic silica; and re-homogenizing the lipid phase comprising the hydrophobic silica and the hydrophilic silica by rotary mixing at a rotation speed of at least 1000 rpm. |
