Point of Interest

The home of SwiftCraftyMonkey! Join Susan as she obsesses about cosmetic chemistry and other things (some possibly related to monkeys). Often strange, occasionally useful, and always worth a stop as a point of interest on your journey through the Intertron.

Substantivity

Substantivity is defined as “an adsorption phenomenon by which materials that have opposing charges or like composition are more readily adsorbed onto or attracted to its surface and, once there, resistant to subsequent rinse-off.” In other words, a material that is positively charged – like our cationic ingredients – will be attracted to the surface of our hair, which is negatively charged or anionic.
