Thorium(IV) oxide has binding characteristics.

Binding ingredients in cosmetic products help hold the product together and keep it from separating. They also help improve the product's texture, stability, and effectiveness and make application easier. These ingredients are usually added in small amounts to the product formulation and may be derived from natural or synthetic sources.

Common binding ingredients in cosmetics include waxes, thickeners, and emulsifiers. Waxes help to give the product a smooth and creamy texture, while thickeners make it thicker and more luxurious. Emulsifiers help to combine water and oil-based ingredients, which is important for many cosmetic products.
