N,N-BIS(2-HYDROXYETHYL)-P-PHENYLENEDIAMINE SULFATE
N,N-BIS(2-HYDROXYETHYL)-P-PHENYLENEDIAMINE SULFATE is an aromatic hair-colour substance supplied as a sulfate salt. Its long name appears on colour-product ingredient lists because it identifies a member of the phenylenediamine family used in dye systems that work through oxidation.
N,N-BIS(2-HYDROXYETHYL)-P-PHENYLENEDIAMINE SULFATE: what it is
N,N-BIS(2-HYDROXYETHYL)-P-PHENYLENEDIAMINE SULFATE is an aromatic hair-colour substance supplied as a sulfate salt. Its long name appears on colour-product ingredient lists because it identifies a member of the phenylenediamine family used in dye systems that work through oxidation.
The sulfate form matters because it is the specific form used in this type of product, rather than a general label for any phenylenediamine. Similar-looking names on an ingredient list can therefore refer to different substances, each with its own conditions of use.
N,N-BIS(2-HYDROXYETHYL)-P-PHENYLENEDIAMINE SULFATE: what it does in cosmetics
In an oxidative hair-colour product, this ingredient takes part in producing colour while the prepared mixture is left on the hair. Its practical purpose for someone choosing a dye is to change the shade of the hair; it is not a treatment active or an ingredient intended to make hair feel softer on its own.
Use depends on the mixture being prepared as directed for the product, since that is the context in which the substance is intended to colour hair. Its name on the label identifies one component of the colour system and, by itself, cannot predict the finished shade.
N,N-BIS(2-HYDROXYETHYL)-P-PHENYLENEDIAMINE SULFATE: conditions and care
Restricted to oxidative hair-colour products: after mixing, the concentration applied to hair must not exceed 2.5%. Do not use with nitrosating agents; the label must state the mixing ratio and allergy-reaction warnings.
