stearic acid for skin
If a polymer already has a plasticizer added, fatty acids in the mixture become external lubricants. Stearic acid is not a carcinogen in humans. Stearic acid (SA), sometimes also called octadecanoic acid, is a saturated long-chain fatty acid. So first let us understand what stearic acid is. The Cosmetic Ingredient Review (CIR) Expert Panel evaluated the scientific data and concluded that stearic acid is safe for use in cosmetic products.THIS SITE IS FOR INFORMATIONAL PURPOSES ONLY AND SHOULD NOT BE USED AS A SUBSTITUTE FOR ADVICE OR TREATMENT FROM A QUALIFIED MEDICAL PROFESSIONAL.THE OWNER OF THEDERMREVIEW.COM HAS MATERIAL BUSINESS RELATIONSHIPS WITH ADVANCED DERMATOLOGY AND FORMULYST, WHOSE PRODUCTS WE ALSO REVIEW AND RANK.
In emulsions, Stearic Acid is an effective stabilizer, thickener, and softener that contributes a cooling sensation on the skin. These sources are heated and pressurized in order to isolate and remove stearic acid.It then goes a process that involves distillation, steaming and cooling in order to create a finished product of concentrated SA, which is usually a waxy substance.Additionally, it is found in some supplements, including.Although the consumption of commercially hydrogenated fats is not recommended, since these are found in packaged foods that are linked to various health problems, SA is also used to create these fats.You’ll find stearic acid listed on product labels under several different names, some which include:Because SA is sometimes sourced from animals, it’s not always suitable for vegans or found in vegan cosmetics.

Much more research is needed in this area to assess the potential of stearic acid as a therapeutic agent.”.The Food and Drug Administration (FDA) includes stearic acid on its list of direct food additives considered Generally Recognized As Safe (GRAS). Once again, stearic acid reduces the surface tension by positioning itself at the oil/water or air/water interface, which has a stabilizing effect on the emulsion.Another property of stearic acid is its ability to function as a thickener or hardener.
