Ingredients higher up in an ingredient list are typically present in a larger amount. 1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse. It is a: Humectant, drawing moisture into the skin Emollient, helping to soften skin Solvent, dispersing and stabilizing formulas Preservative booster, enhancing the antimicrobial activity of other preservatives Allantoin is a soothing ingredient known for its protective and moisturizing properties; it's basically a quiet workhorse ingredient you can find in a huge range of cosmetics. Though it can be derived from the comfrey plant, allantoin is produced synthetically for cosmetic products to ensure purity. Research shows it can encourage your skin cells to turn over and renew by stimulating keratinocyte and fibroblast proliferation. It also has mild keratolytic properties to help loosen and shed dead skin cells without being harsh. Studies also suggest allantoin can help calm inflammation by dialing down some of the chemical signals your skin sends out when it is irritated. This ingredient is typically used in the 0.1-0.5% range, and the FDA recognizes it as a skin protectant in OTC products up to 2%. Overall, allantoin is a wonderful addition to most routines; it is stable across a wide pH range (~4-8), works well with other ingredients, and is considered non-sensitizing/non-irritating. Fun fact: Allantoin is naturally occurring in comfrey root, beets, chamomile, and wheat sprouts. Our bodies even produce it as a byproduct of uric acid metabolism. Ammonium Acryloyldimethyltaurate/Vp Copolymer is a synthetically created polymer. It's used as a film-forming agent and used to thicken the consistency of products. Think of it as a supportive ingredient that helps your gel-creams feel silky, "cloud cream-like", and spread evenly without being greasy. The Cosmetic Ingredient Review (CIR) Expert Panel evaluated it (along with 22 other acryloyldimethyltaurate polymers) and concluded it's: Due to its large molecular size, it sits on the surface of skin rather than penetrating it. Betaine is a humectant. Like hyaluronic acid, it helps attract and retain moisture in the skin. It’s known for being gentle and for helping the skin maintain balanced hydration. Betaine is mainly used to improve hydration and support calmer skin. It helps skin cells regulate water balance because it functions as an osmolyte. Some studies suggest betaine may support making skin tone more even. Fun fact: Betaine naturally exists in the skin and the body. In cosmetic products, it can be either plant-derived (most commonly from sugar beets) or synthetically produced for consistency and stability. Betaine is also known as trimethylglycine. 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 type
