![]() I do like the presence of the lecithin in hair and bodycare products however and I have used it in hundreds of balms, deodorants and other waterless formulations or bar products (with a low water content). There are enough attractive and easy to work W/O emulsifiers available these days that work cold or hot process with amazing outcomes in terms of stability and skin feel. To be honest, I personally never liked W/O emulsions made with lecithin although this is one of my favorite ingredients. It is rather difficult to create stable emulsions and the process is very heat sensitive. Working with lecithin as a W/O emulsifier is quite a hassle and the outcomes are usually not that amazing. ![]() Both lysolecithin and ecogel are much more expensive than the native lecithins. The popular ecogel which is both an emulsifier and a stabilizer contains lysolecithin as well. We do have a lysolecithin in our shop and have already published a few sample formulations with it. These are basically calles lysolecithins and are used as an O/W emulsifier. There are more hydrophilic versions of lecithin available now which are obtained by hydrolysing lecithin. Lecithin has been used as a W/O emulsifier for a very long time. The following chart depicts the difference in glycerophospholipid content of some plant oils. Phosphatidic acid, Phosphatidylcholine (PC), Phosphatidylethanolamine (PE), Phosphatidylinositol (PI), Phosphatidylserine (PS) and phosphatidylglycerol (PG). Lecithins from different sources differ mainly in the components of the glycerophospholipids. Soy bean, sunflower and rapeseed are the main sources of commercially available lecithin. The following chart depicts the lecithin content of various plants. It is a penetration enhancer and accelerates penetration of active ingredients and drug components, it is an amollient and a barriere enhancer. Lecithin was first isolated from the egg yolk by a 19th century French chemist.īecause of its unique structure and composition, it is now used as a dietary supplement, in pharmaceuticals and mostly in skin care and topical drugs. Lecithins are found in plant and animal tissues and depending on the tissue and the origin the composition of the lecithin may be different. It is actually a generic name for a group of lipophilic ingredients containing fatty acids, sterols, triglycerides, glycolipids and phospholipids. Lecithin is an amazing natural ingredient in skin care, nutrition and pharmacy.
