| Introduction | Humolyl ester (Homosalate), also known as protomembrane ester, is a typical salicylic acid ultraviolet absorber, chemically named 3,3, 5-trimethylcyclohexylsalicylate, which can absorb UVB295 ~ 315nm ultraviolet rays, it has been approved by FDA, Europe, Japan and Australia for sunscreen chemicals to protect skin from UVB radiation damage. It is widely used in sunscreen, toner and other cosmetics and clothing fabrics. |
| prepare | 250ml three-mouth bottle add 10.0g of methyl salicylate, 14.0g of 3,3, 5-trimethylcyclohexanol, mix evenly, add 5.0g of carbonic acid potassium, raise the temperature to 120-130 ℃ for 10h, and monitor the conversion rate of methyl salicylate to 85.6% by gas chromatography. Decompression was distilled to obtain 12.2g of colorless and transparent humolate with 70.8% yield and GC purity greater than 99%. |
| biological activity | Homosalate is an organic compound that is used as a sunscreen to filter ultraviolet rays and protect the skin from sunlight damage. |
