PURPOSE:To obtain an O/W type or a W/O type emulsion type cosmetic having improved shelf stability, skin safety, spreading and extending properties, by blending a chitin derivative with a dextrin fatty acid ester with a surface active agent, an oily substance and water. CONSTITUTION:A emulsion type cosmetic obtained by blending at least one chitin derivative (preferably one having >=1,000 dalton molecular wight) selected from a group consisting of glycol chitin, carboxymethyl chitin, a salt thereof and sodium chitin sulfate with a dextrin fatty acid ster, a surface active agent (anionic type or nonionic type), an oily substance and water. The blending ratio of each component based on sum of the cosmetic is preferably 0.2-5.0wt% chitin derivative and 0.3-5.0wt% dextrin fatty acid ester, 10-70wt% oily substance (wax, etc.) and usually 20-80wt% water. The blending ratio of the surface active agent is 1.0-3.0wt% in the case of sorbitan sesquioleate. |
