高保湿性能、稳定性良好O/W乳剂型粉底液的研制

Preparation of a Good Stability and Moisture of the O/W Foundation

设计、制备O/W乳剂型粉底液,并测定其相关性能。采用搅拌、高速分散均质制备粉底液,以高速离心、低温、高温加速破坏试验考查配方稳定性,以人体皮肤水分含量表征其保湿效果,采用原子吸收测定其重金属(汞、砷、铅)含量。制备了稳定性、保湿作用良好的O/W乳剂型粉底液,重金属砷、铅、汞符合GB/T 7916—1987。说明该配方设计的合理性,和制备方法的可行性。

The formula of O/w foundation emulsion was devised and its relative capabilities were tested Through mixture and dispersion with high speed, an O/W foundation emulsion was made. The stability of the formula was evaluated, by high speed centrifugation and temperature accelerating test. The efficacy of its moisture retention was determined by the levels of skin moisture and its content of hydrargyrum, arsenic and plumbum were also tested by AAS. An O/W foundation emulsion with good stability and moisture retention was prepared and its content of Hg,As and Pb comply with the standard GB7916-87 of China.
