Stearic Acid is a vegetable source fatty acid used to thicken and stabilize formulations. Used in creams and lotions, it can be partially neutralized with triethanolamine or other alkalis to form an in-situ soap (sodium stearate) which acts as a secondary emulsifier. It is used as a hardener in stick products and in soap. stearic acid might be classified as non-comedogenic due to its fairly low rating 2.
Cosmetic Benefits of Stearic Acid:
It’s a Surfactant and Therefore A Cleanser: Surfactants or surface-active agents are one of the primary and active ingredients in cleaning detergents. As a surfactant, stearic acid makes it easier for water, oil, and dirt to bind together, so they can be easily removed. The reason why stearic acid is good for the skin in this regard is that it cleanses without stripping your skin of its natural oils and leaving it dry.
Has Moisturizing Properties: It is an emollient or moisturizer that softens, smoothes, and lubricates the skin. That’s why it’s commonly used to add moisturizing properties to skin care products. For instance, it increases a product’s capacity to hold more water in proportion to oil.
Helps Maintain Your Skin’s pH: As mentioned, stearic acid is not like other strong and corrosive acids, like hydrochloric acid, which has a pH of 0. When it comes to acids, the lower the pH, the stronger the acid. The good news is, stearic acid has a pH of between 5.5 and 6, meaning it’s closer to the pH of water, which sits at neutral seven. As a mild acid, stearic acid perfectly matches the skin’s ideal pH, which ranges from 4.7 to 5.75.
Strengthens the Skin’s Barrier: Since it is a moisturizer that prevents water loss it can help maintain and strengthen the skin’s protective barrier. Your skin produces natural oils that keep moisture locked in while insulating you from irritants, allergens, and bacteria. Stearic acid improves this function of the skin, unlike other harsh products which can damage or disrupt the skin barrier
