Is Hydrogenated Lecithin Safe?
The safety of lecithin and hydrogenated lecithin has been assessed by the Cosmetic Ingredient Review Expert Panel. The Expert Panel evaluated the scientific data and concluded that lecithin and hydrogenated lecithin are safe as used in rinse-off products. However, the Panel limited the use of lecithin and hydrogenated lecithin in leave-on products to concentrations less than or equal to 15 percent.
Since hydrogenated lecithin functions as a penetration enhancer, caution should be exercised when it is combined in formulations with other ingredients that may be harmful if absorbed through the skin.
It is possible for some people to have allergies to hydrogenated lecithin since it can be derived from soybeans, eggs, and milk, which are common allergenic foods. Those that are highly sensitive to these foods might react to hydrogenated lecithin
