Uses

Different sources of media describe the Uses of 118-60-5 differently. You can refer to the following data:
1. Solvent for solid sunscreens.
2. 2-ethylhexyl salicylate is also known as ethylhexyl salicylate and octyl salicylate. It is a uVB absorber.
3. ethylhexyl salicylate is an FDA-approved uVB sunscreen chemical, it absorbs within the entire uVB range. It has an approved usage level of 3 to 5 percent in both the united States and the european union, and is a good solubilizer for benzophenone-3. In suntan lotions, it is used as a preservative and anti-microbial. This is a salt of salicylic acid occurring in wintergreen leaves and in other plants. It is also synthetically manufactured. It is considered a non-comedogenic raw material. This is the InCI name for octyl salicylate.
4. octisalate is a uVB protector. This is the drug name for ethylhexyl salicylate and octyl salicylate.

Preparation

From 2-ethylhexanol and salicylic acid by azeotropic-type esterification (Arctander, 1969).

Brand name

Escalol (ISP Van Dyk); Neo Heliopan (Haarmann & Reimer, Germany); Uvinul (BASF). Note—The International Cosmetic Ingredient (INCI) name for octisalate is octyl salicylate.

General Description

A method for production of salicylic acid isooctyl

The invention provides a method for industrially producing ethylhexyl salicylate. The method comprises the steps of esterifying salicylic acid and isooctyl alcohol in an n-heptane solvent under sodium hydrogen sulfate serving as a catalyst to synthesize a coarse ethylhexyl salicylate product, and enabling the salicylic acid conversion rate to be greater than or equal to 99 percent and the isooctyl ether generation amount to be less than 1 percent by controlling the backflow temperature to be 110+/-5 DEG C and the backflow water division time to be 8-10 hours; then performing decompression rectification, effectively separating impurities with different boiling points by controlling the temperature of circulating water of a built-in backflow condenser to obtain a high-purity ethylhexyl salicylate product, wherein the product yield is greater than or equal to 95 percent, and the purity of a product detected by GC (gas chromatography) is greater than or equal to 99.5 percent. The esterifying synthesized catalyst and the non-reacted salicylic acid can be both recycled and directly used for synthesis of the next batch, so that raw materials are saved and the cost are reduced. The synthesis method is reasonable in design, easy to operate and suitable for being popularized and industrialized.
