What is Propylparaben in Skin Care?

A preservative is a substance that prevents the growth of microorganisms within a product or prevents the growth of microorganisms that react with the product. In cosmetics, the role of preservatives is to protect products from microbial contamination, prolong product shelf life, ensure product safety, and prevent consumers from possible infections caused by using microbially contaminated products. The product avoids secondary pollution during consumer use. However, as a chemical additive, preservatives may have a potential impact on the human body if the amount is too large, so how to reduce the amount of preservatives in cosmetics and balance the amount of preservatives and their antibacterial effects is particularly important.

Propylparaben in Skin Care, also known as paraben, is a kind of high-efficiency food preservative, which has good ability to inhibit bacterial reproduction and prevent fermentation, and its antibacterial performance is stronger than that of benzoic acid and sorbic acid. Paraben ester preservatives are low-toxic. Humans take paraben ester for a long time, and the part that is not hydrolyzed by esterase in the body into the metabolite p-hydroxybenzoic acid will be directly absorbed and stored in human tissues, thus harming human health. cause serious impact.

Studies have shown that Propylparaben in Skin Care has estrogenic activity and plays an important role in the development of breast cancer. The national standard GB2760-2011 stipulates that the maximum amount of methyl paraben and Propylparaben in Skin Care in oyster sauce, shrimp oil, fish sauce and other products is 0.25g/kg, and does not stipulate the maximum limit of paraben in aquatic products. At present, the detection methods of parabens include high performance liquid chromatography, capillary electrophoresis, ultraviolet spectroscopy, gas chromatography, gas chromatography-mass spectrometry, liquid chromatography-mass spectrometry, etc.
