And now you’re saying, wait, that should mean that it should remove the cationic stuff because it has a negative charge and opposites attract. Shampooing is not always a solution because most shampoos are based on anionic (negatively charged) surfactants. Not unless you experience symptoms of build-up. Having these ingredients on your hair is not a problem in itself. This is known as “substantivity” in cosmetics chemistry. Electromagnets that are used in scrap metal yards. Imagine magnets – the positive end of the quaternary cationic surfactant bonds to the negative hair. Most of these are not water soluble, but water-solubility doesn’t much matter because they’re bonding to your hair. Quaternary cationic surfactants include ingredients such as:īehentrimonium chloride, Behentrimonium methosulfate, Cetrimonium bromide, Cetrimonium chloride, Stearalkonium chloride, Dicetyldimonium chloride, Guar hydroxypropyltrimonium chloride. Quaternary Cationic Surfactants: ©Science-y Hair Blog 2013 Straight hair might get stringy or increase in volume (not necessarily in a good way). Wavy, curly or coily hair might not pull together in it's proper curl pattern when you have build-up. Cationic polymers in styling products (Polyquaternium-4, for example) also bond to hair to form a film that provides hold and humidity resistance.īuild-up tends to look like you'd rubbed your hair with a balloon (static-y, flyaway, self-repellant). ![]() Quaternary cationic surfactants (and cationic polymers) are the real “conditioners” in hair and skin products. It is also more likely for the owner of low-porosity hair to notice / experience "product build-up." Low porosity hair has fewer negative charges to adsorb conditioners and cationic ingredients. More-damaged hair (the ends, heat-styled, sun-damaged, chemically relaxed, permed, highlighted) has more negative bonds and will bond with or "adsorb" more cationic ingredients. Opposites attract (positive and negative) when it comes to hair and conditioner. Hair has a net negative charge at the pH environment in which it usually exists (somewhere between pH 4.5 and 5 is average). First off, cationic means something has a net positive charge (+). Here I’m referring to 2 classes of chemicals: Quaternary cationic surfactants and cationic polymers. When they're good, they're very good and when there is too much, you feel "build-up." Cationic ingredients that bond to the hair. Oily residues like actual oils and butters, creamy ingredients like Cetyl alcohol and other emollient ingredients.
