    Dispersing Agent - an overview | ScienceDirect Topics

    In enclosed vessel, they may also act as reducing agents destroying some azoic disperse dyes. Modern dispersing agents are high-molecular weight compounds and some may be polymeric versions of sodium dinaphthylmethane sulphonate. Anionic dispersing agents may be based on methylated naphthalene sulphonic acid-formaldehyde condensate.
