Abstract:
PURPOSE: A method for controlling viscoelasticity of emulsion type cosmetics using extract of Astragalus membranaceus is provided to obtain an antioxidant effect and offer technology which improves viscoelasticity of emulsion. CONSTITUTION: A method for controlling viscoelasticity of emulsion type cosmetics improves viscoelasticity of emulsion and obtains an antioxidant effect at the same time by including extract of Astragalus membranaceus. The emulsion comprises a normal emulsifier. The extract of Astragalus membranaceus is extracted by using 1,3-butylene glycol as an extraction solvent. The extract of Astragalus membranaceus is in a range of 0.01-0.1 weight % based on the whole amount of the emulsion. [Reference numerals] (AA) Comparative example; (BB) Example 2; (CC) Example 1
