Usage

General Description

PEG-2 DILAURATE is a chemical compound that is a polyethylene glycol derivative of lauric acid. It is commonly used in cosmetics and personal care products as an emulsifier, surfactant, and skin conditioning agent. PEG-2 DILAURATE helps to blend oil and water-based ingredients in products such as lotions, creams, and shampoos, and also helps to improve the spreadability and texture of these formulations. It is considered to be safe for use in cosmetics when used in accordance with regulations and at appropriate concentrations. However, there are some concerns about its potential to be contaminated with harmful impurities during the manufacturing process.

Fat Hydrolysis and Esterification by a Lipase from Humicola lanuginosa

The hydrolysis and esterification by a thermostable lipase from Humicola lanuginosa No. 3 were investigated.Both reactions occurred readily at temperatures between 45-50 deg C.Esterification by the enzyme with glycerol was observed to be specific towards fatty acids with carbon numbers of C12-C18.Lauric acid esters with different alcohols such as primary alcohols, terpene alcohols, etc., were also synthesized readily.Esterification by the enzyme was adversely affected by the water content (optimum, ca. 7percent), however, the hydrolysis rate increased rapidly with increasing water content (optimum, ca. 60percent).The enzyme showed increased activity in organic solvent-aqueous reaction systems.Nevertheless, hydrolysis in complete organic phase reactions was found not to be feasible.Hydrolysis at a higher temperature (50 or 55 deg C) in a solvent free phase was almost the same as that in organic solvent-aqueous phase reactions.The components of glycerides varied considerably during hydrolysis, whereby esterification resulted in a higher quantity of mono- and diglycerides (about 40percent), compared to in the case of hydrolysis, for which the value was about 10-20percent.
