Title:
LIQUID CRYSTAL EMULSIFICATION COMPOSITION AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2020/138000
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a liquid crystal emulsification composition that is viscous petroleum jelly-like but is less sticky after being applied. As a solution to the problem, provided is a liquid crystal emulsification composition characterized by containing (A)-(G) in the following proportion. (A) 1-8 wt% of one or both of: a hydrophilic surfactant (a1) which is a polyoxyethylene polyoxypropylene alkylether represented by general formula 1; and a hydrophilic surfactant (a2) which is a polyoxy ethylene alkylether represented by general formula 2. General formula 1: HO(C2H4O)n-(C3H6O)mR (In the formula, n is 15-50, m represent an integer of 1-16, and R represents an alkyl group having a carbon number of C12-C24.) General formula 2: HO(C2H4O)nR (In the formula, n is 15-50, and R represents an alkyl group having a carbon number of C12-C24.) (B) 1-8 wt% of one or both of: a hydrophilic surfactant (b1) which is a polyoxy ethylene fatty acid derivative in which an alkyl group has a carbon number of C15-C24 and in which the number of added moles of polyoxy ethylene is 15-60; and a hydrophilic surfactant (b2) which is a polyoxy ethylene-hydrogenated castor oil and in which the number of added moles of polyoxy ethylene is 20-100. (C) 2-8 wt% of a non-hydrophilic surfactant. (D) 5-30 wt% of oil content. (E) 15-80 wt% of a water-soluble alcohol. (F) 1-8 wt% of trimethylglycine. (G) 8-40 wt% of water.
