Lash Sensational Sky High Mascara Very Black Waterproof

A lightweight hydrocarbon that gives formulas a smooth, silky feel. Used in color cosmetics and sunscreens. Well tolerated and inert.

A natural wax secreted by honeybees, used as an emollient and texture builder in balms and salves. It is generally well tolerated. People with bee or pollen allergies should patch test, as rare sensitization has been documented.

A plant-derived wax from carnauba palm leaves, widely used in cosmetics to provide texture and protective film-forming properties. Extensively documented as safe for topical use.

A quaternized clay mineral used to thicken and suspend products. CIR found it safe as used, though the mineral base means trace amounts of inhalable silica particles exist if the powder form is aerosolized. It is well tolerated in leave-on and rinse-off cosmetics when formulated properly.

The base most products are built on. It carries the other ingredients and has no safety concern.

A fast-evaporating solvent used to carry actives and give toners a light, "clean" feel; at the concentrations used in classic astringents it can be genuinely drying or irritating with repeated use, especially on dry or compromised skin, though it is not inherently toxic and is a normal, well-studied cosmetic ingredient.
