Abstract

Abstract: Two ways for assessment and prediction of long-term physical stability of emulsion cosmetics,centrifugation in combination with near infrared irradiation and cold-hot cycling,were conducted and compared.Results showed that the unstablization process of samples generated from separate formulation systems is different and the centrifugation method cannot accelerate all kinds of the unstablization process.The centrifugation in combination with near infrared irradiation method can rather accurately predict the stability of samples with similar formulation system and makes important sense in the raw material screening and selection period and the formulation development period as well as for the quality-control in production.However,for samples of completely different formulation system,the simple centrifugation in combination with near infrared irradiation method is not sufficient to predict and judge the stability of the product.
