Silybum Marianum Ethyl Ester is derived from the oil of the Lady’s Thistle, scientifically known as Silybum marianum (L.), which belongs to the Asteraceae family. This ingredient is also known by other names such as Milk Thistle Ethyl Ester. The primary component of this ester is the fatty acids extracted from the seeds of the Lady’s Thistle, which are then chemically modified to form the ethyl ester.
Historically, the Lady’s Thistle plant has been renowned for its medicinal properties, particularly in liver health and detoxification. However, its journey into the cosmetic industry is relatively recent. The shift occurred as researchers began to explore the skin-conditioning benefits of its fatty acids. The ethyl ester form was developed to enhance the stability and efficacy of these fatty acids when applied to the skin.
The production process of Silybum Marianum Ethyl Ester involves extracting the oil from the seeds of the Lady’s Thistle plant. This oil is rich in beneficial fatty acids. These fatty acids are then subjected to an esterification process, where they react with ethanol to form the ethyl ester. This chemical transformation not only stabilizes the fatty acids but also makes them more easily absorbable by the skin, thereby enhancing their conditioning properties.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Silybum Marianum Ethyl Ester:
Silybum Marianum Ethyl Ester is primarily known for its skin conditioning properties. This means it helps to maintain the skin in good condition.
