The adjective 'non-staining' describes a substance, material, or product that does not leave a mark or discoloration on a surface or material it comes into contact with. This property is highly desirable in various applications, ranging from personal care products to industrial coatings. The key characteristic is the lack of permanent or noticeable color transfer. Substances described as non-staining typically resist adherence to surfaces or are easily removed without leaving a residue that alters the appearance of the underlying material. This makes them ideal for applications where aesthetics or the preservation of the original surface are important, such as in cosmetic formulations or in the handling of delicate fabrics. The efficacy of a non-staining product can depend on various factors including the substance, the type of surface, and the duration of contact.
