Ingredients higher up in an ingredient list are typically present in a larger amount. Ammonium Polyacryloyldimethyl Taurate is a polymer made from ammonium salts. It works as a thickener, emulsifier, and texture enhancer that gives gel-creams a silky, lightweight feel. This ingredient is versatile and low-maintenance so manufacturers love working with it. Typical usage levels in cosmetics are usually low and in the range of 0.015 - 2.3%. Butylene Glycol (or BG) is used within cosmetic products for a few different reasons: Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients. Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness. Caprylyl Glycol is a humectant, skin conditioner, emollient, and preservative booster derived from either caprylic acid or synthetically created. Typical use levels vary from 0.3-1% as a preservative booster and go up to 2% to condition skin. Because it is not a free-fatty acid, this ingredient is fungal acne safe (there's nothing for Malassezia to feed on). Dicaprylyl Ether is created from caprylic acid. It is a texture-enhancer and emollient. As an emollient, Dicaprylyl Ether is non-comedogenic. It helps soften and smooth the skin by creating a barrier on top. This barrier helps trap moisture in, helping to hydrate the skin. Dicaprylyl Ether gives a non-greasy feel and better spreadability to products. Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum. Topically, glycerin does several things at once: Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3. Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin. This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products. Just know very high concentrations (>40%) can feel tacky in low humidity. Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine. Glycine Soja Oil is a plant-derived oil from soybean seeds. Like other oils, it is rich in essential fatty acids (mostly linoleic and oleic) that support skin hydration and barrier function. The fatty acids are able to integrate into the lipid matrix of the stratum corneum to help soften skin and reduce water loss. On top of that, soybean oil is rich in vitamins like vitamin E, a potent antioxidant. Research on soybean's active components also point to anti-inflammatory, collagen-stimulating, antioxidant ac
