Open Data Verified Data
Put 1mol of polyethylene glycol 600 into a reactor, heat and melt, and add a catalyst amount of heteropoly acid and 2mol of lauric acid under stirring. Reflux under vacuum for 6 hours, sample and measure the acid value to 4-5mgKOH/g. Use an appropriate amount of hydrogen peroxide to decolorize, centrifuge, filter, and dry before packaging to obtain the finished product.

639 - Introduction
Polyethylene glycol (600) dilaurate is a chemical substance, which is the esterification product produced by the reaction of polyethylene glycol (PEG) with dilauric acid. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: Polyethylene glycol (600) double laurate is often a colorless or slightly yellow liquid.
-Solubility: It is insoluble in water, but can be dissolved in organic solvents.
Use:
-Emulsion stabilizer: Polyethylene glycol (600) dilaurate is widely used in cosmetics and personal care products. It can increase the viscosity of the product, improve its texture, and help stabilize the dispersion system.
-Penetration enhancer: Polyethylene glycol (600) dilaurate can help the penetration of drugs on the skin, so it is used as a penetration enhancer in the drug delivery system.
Preparation Method:
The preparation of polyethylene glycol (600) dilaurate is mainly obtained by esterification of polyethylene glycol and lauric acid in the presence of an acid catalyst.
Safety Information:
-Polyethylene glycol (600) dilaurate is generally considered to be a relatively safe chemical, but the following matters still need to be paid attention:
-avoid contact with skin and eyes, such as contact should immediately rinse with plenty of water.
-Avoid inhaling its vapor or mist, and ensure that the operation is carried out in a well-ventilated place.
-When storing and using, appropriate laboratory safety procedures should be followed.
-If necessary, use under professional guidance.
