Abstract

|
Water-soluble collagen (30 wt%) was entrapped within oil phase of lipstick using reversed micelle methodto improve the moisture capacity of the lipstick. Reversed micelles containing collagen were prepared using caprylic/capric triglyceride as external phase and polyoxyethylene (10) octylphenyl ether (Triton X-100) and 1-dodecanolas surfactant and co-surfactant, respectively. The formation of reversed micelle encapsulating collagen was confirmedby measuring electric conductivity and UV-vis spectrum using methylene blue (MB). The stability and moisture capacityof the lipstick containing 20 wt% collagen encapsulated reversed micelles were observed by measuring rheology property,moisture content and amino acid content. The molecular ratio (W, water-pool) of water to surfactant (Triton X-100)in the most stable reversed micelle was ≤ 10. The hardness of the lipstick had no difference with that of the lipstickwithout reversed micelle, and the moisture content was increased to 59% and the amino acid content was 92.7%.
