Ingredients higher up in an ingredient list are typically present in a larger amount. Alumina (aka aluminum oxide) is an inorganic mineral powder refined from bauxite that works as a quiet workhorse in a formula. It shows up often as an abrasive, absorbent, anticaking, bulking, and viscosity-controlling agent. One of its most common jobs is acting as a pigment carrier and dispersant. Alumina platelets are often blended with inorganic sunscreens like Titanium Dioxide (or with colorants) and then coated with a silicone such as Triethoxycaprylylsilane so the pigment spreads evenly and smoothly. In makeup, it can also double as a light-diffusing powder or oil absorber to keep formulas from looking greasy. The Cosmetic Ingredient Review Expert Panel has concluded alumina to be safe in present practices of use and concentration. They note it's a stable, oxidized compound and scientific research has failed to establish links to health issues. Concentrations vary depending on the product: Ascorbyl Glucoside (AA-2G) is one of the most stable vitamin C derivatives out there. It's made by attaching a glucose molecule to ascorbic acid; this glucose "cap" shields the vitamin C from air, light, heat, and metal ions that normally cause pure ascorbic acid to oxidize. Once on your skin, the enzyme alpha-glucosidase snips off the glucose and gradually releases active ascorbic acid right where it's needed. Basically, it behaves like a slow-release pro-vitamin C with less of a stinging that high-strength ascorbic acid can cause. The research supports the classic vitamin C benefits as well. In lab and human studies, AA-2G slowed down the skin's production of melanin (the pigment behind dark spots) and helped shield skin cells against sun damage better than ascorbyl phosphate. These studies also showed AA-2G released vitamin C over a longer period. A frequently cited manufacturer trial found that a 2% AA-2G face cream significantly improved wrinkle depth and skin roughness after 45 days. And in 2009, a clinical trial showed it meaningfully lightened dark patches on the gums compared to a placebo. There's also collagen-synthesis support (since vitamin C is a required cofactor for that) and an antioxidant effect too. Typical usage is usually between 0.5-5% and most studies/products land around 2%. AA-2G performs best when formulated at a mildly acidic pH (~5-7) which is much gentler than the pH that pure vitamin C demands (~2.5-3.5). Just one thing worth knowing: the in-skin conversation rate is only about 55-60% by weight. So a 5% AA-2G product delivers roughly 2.75-3% of actual active vitamin C. On top of that, skin absorption is relatively low because the ingredient is water-soluble. 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
