Usage

General Description

Heptyl stearate is a chemical compound composed of heptyl alcohol and stearic acid. It is a clear, odorless liquid that is commonly used as an emollient and skin conditioning agent in cosmetics and personal care products. Heptyl stearate acts as a moisturizer, helping to soften and smooth the skin by forming a protective barrier to prevent moisture loss. It is also used as a lubricant in various industrial applications, such as in the production of plastics and rubbers. Additionally, heptyl stearate is found in some pharmaceutical formulations and is generally considered safe for use in skincare products when used in accordance with regulatory guidelines.

Specific enzyme-catalyzed hydrolysis and synthesis in aqueous and organic medium using biocatalysts with lipase activity from Aspergillus niger MYA 135

In the present study, the specific hydrolytic activity of three biocatalysts such as the constitutive mycelium-bound lipase, the induced mycelium-bound lipase and the lyophilized induced supernatant from A. niger MYA 135 was evaluated in both aqueous and organic media.A direct correlation between activity in water and n-hexane was not observed for the same hydrolytic reaction. The n-hexane/water activity ratio (RO/A) was applied to characterize the activity in organic medium. The three biocatalysts showed RO/A values higher than 1 for hydrolysis of long-chain fatty acid esters, demonstrating a higher specific hydrolytic activity in organic solvent than in water. A different behavior was observed during hydrolysis of middle-chain fatty acid esters, which was higher in aqueous medium (R O/Adw) observed in a reaction mixture containing propanol and p-nitrophenyl laurate. Finally, both p-nitrophenyl caprate (C10) and p-nitrophenyl laurate (C12) were preferentially methanolized by the lyophilized induced supernatant, being this lipase activity the most specific biocatalyst preparation under transesterification conditions. A selectivity-based analysis of each lipase preparation toward transesterification or hydrolysis in organic medium was evaluated as well. Springer Science+Business Media, LLC 2012.
