Lecithin ●
TL;DR. This ingredient primarily acts as a natural emulsifier, helping oil and water phases stay blended. It also supports skin conditioning and can help form liposome-style delivery systems in serums and creams.
What does Lecithin do in a cosmetic formula?
This ingredient primarily acts as a natural emulsifier, helping oil and water phases stay blended. It also supports skin conditioning and can help form liposome-style delivery systems in serums and creams.
Is Lecithin clean?
This ingredient is generally well accepted in clean-beauty frameworks and is typically well tolerated on skin. The main watch points are source transparency, such as soy or egg origin, potential allergen labeling, and non-GMO preferences.
Is Lecithin sustainable?
This material is usually sourced from plant oils, most often soy or sunflower, and is often a byproduct of edible oil refining. It is biodegradable and renewable, with sustainability quality depending on crop practices, traceability, and deforestation controls.
Is Lecithin COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when sourced and processed according to the standard. It fits Green Chemistry reasonably well because it can come from renewable feedstocks, biodegrades readily, and performs without high concern solvents when properly manufactured.
How does Lecithin work chemically?
The molecule profile is a mixture of amphiphilic phospholipids with fatty acid chains and polar head groups, which lets it sit at oil-water interfaces and form lamellar structures. Typical use levels are about 0.1 to 5% depending on whether it is used for emulsification, skin feel, or vesicle formation, and formulas should account for oxidation sensitivity from unsaturated lipid chains.
