GlossaryPhysical Stability

ability to maintain original physical properties over time

Physical stability refers to the ability of a substance or product to maintain its original physical properties over time under various environmental conditions. For example, in the context of hair care products, physical stability would mean that a shampoo or conditioner retains its consistency, color, and effectiveness without separating, crystallizing, or degrading when stored at different temperatures or humidity levels. This ensures that the product remains safe and effective for use throughout its shelf life.
