What is Propylparaben Inci?

Preservatives are substances that prevent the growth of microorganisms within a product or that react with the product. In cosmetics, the role of preservatives is to protect the product from microbial contamination, prolong the shelf life of the product, ensure the safety of the product, prevent possible infection by consumers due to the use of microbially contaminated products, and at the same time make The product avoids secondary pollution during consumer use. However, as a chemical additive, if the amount of preservatives is too large, it may have a potential impact on the human body. Therefore, how to reduce the amount of preservatives in cosmetics and balance the amount of preservatives and their antibacterial effects is particularly important.

Propylparaben Inci, also known as parabens, are a kind of high-efficiency food preservatives, with good ability to inhibit bacterial reproduction and prevent fermentation, and their antibacterial properties are stronger than benzoic acid and sorbic acid. Propylparaben Inci have low toxicity. Human long-term intake of parabens, the part of which is not hydrolyzed into metabolite p-hydroxybenzoic acid by tissue esterase in the body will be directly absorbed and stored in human tissues, which is harmful to human health. cause serious impact.

Studies have shown that Propylparaben Inci have estrogenic activity and play an important role in the development of breast cancer. The national standard GB2760-2011 stipulates that the maximum amount of methylparaben and Propylparaben Inci in oyster sauce, shrimp oil, fish sauce and other products is 0.25g/kg, and the maximum amount of Propylparaben Inci in aquatic products is not specified. . 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 and the like.

Propylparaben Inci Uses

  1. Propylparaben Inci is used as a preservative and antioxidant, also in the pharmaceutical industry.
  2. Propylparaben Inci is used as a bacteriostatic preservative in pharmaceuticals and cosmetics.
  3. Propylparaben Inci is used as an antiseptic bactericide for food, cosmetics, pharmaceuticals, etc.

Propylparaben Inci Preparation

1. Put the silica gel into a drying box, dry it at 150°C for 4 hours, cool it to room temperature, then immerse the silica gel in a perchloric acid solution, soak it for 14 hours, filter it with suction, dry it, and seal it for later use;

2. Add p-hydroxybenzoic acid, n-propanol and the catalyst prepared above in turn to the flask equipped with thermometer, stirrer, water separator and reflux condenser, stir and heat to 85℃-90℃, and react for 3h;

3. After the reaction is completed, filter out the catalyst while hot, steam excess propanol from the filtrate, cool, wash the precipitated solid, filter with suction, and dry to obtain crude ester, which is purified to obtain white Propylparaben Inci.

The preparation method of Propylparaben Inci has the beneficial effects of using perchloric acid-silica gel as a catalyst, high catalytic activity, simple operation, no corrosion to equipment, low price, non-toxic, no pollution to the environment, and is suitable for industrialization Production.
