Usage

Description

N-Lauroylsarcosine, also known as N-lauroyl sarcosine, is a synthetic compound derived from the combination of lauric acid and sarcosine. It is a zwitterionic amphiphilic molecule with both hydrophilic and lipophilic properties, which allows it to interact with various biological and chemical systems. Its unique structure and properties make it a versatile ingredient in various applications.

Uses

Used in Pharmaceutical Industry:
N-Lauroylsarcosine is used as a permeation enhancer in transdermal drug delivery formulations. It increases the fluidity of the stratum corneum lipid structure of the skin, allowing for improved penetration and absorption of drugs through the skin. This enhances the bioavailability and effectiveness of transdermal drug delivery systems.
Used in Cosmetics Industry:
N-Lauroylsarcosine is used as a foam booster and viscosity modifier in cosmetic formulations, such as shampoos, shower gels, and cleansers. Its amphiphilic properties allow it to create a rich lather and improve the texture and stability of the products.
Used in Personal Care Industry:
N-Lauroylsarcosine is used as a mild surfactant and emulsifier in personal care products, such as toothpaste and mouthwashes. Its mildness and ability to form stable emulsions make it suitable for sensitive applications, including oral care products.
Used in Food Industry:
N-Lauroylsarcosine can be used as an emulsifier and foaming agent in the food industry, particularly in the production of beverages and processed foods. Its ability to stabilize emulsions and create foams can improve the texture, appearance, and shelf life of various food products.

Palladium-catalyzed amidocarbonylation - A new, efficient synthesis of N-acyl amino acids

For the first time palladium catalysts have been used successfully for the amidocarbonylation reaction. The activity of the cobalt catalysts that were used exclusively beforehand has now been exceeded by an order of magnitude, and the reaction can be performed under far milder conditions. Palladium-catalyzed amidocarbonylation reactions can now be used for the synthesis of a much wider range of N-acyl amino acids.
