Cetrimide emulsifying ointment

Ion pair titration using a coloured indicator complex is used in pharmacopoeial assays of dicyclamine elixir, procyclidine tablets, sodium dodecyl sulphate and cetrimide emulsifying ointment. 

Cetrimide Emulsifying Ointment, B.P.C, Contains 30 per cent of cetrimide emulsifying wax. It can be standardised by the anionic-cationic titration method (b) described above. 

Comments cationic emulsifying wax is claimed to be of particular value in cosmetic and pharmaceutical formulations when cationic characteristics are important. Thus it can be used in medicated creams, germicidal creams, ointments and lotions, hair conditioners, baby creams, and skin care products in which cationic compounds are included. Cationic emulsifying wax is compatible with cationic and nonionic materials, but is incompatible with anionic surfactants and drugs. Additional antimicrobial preservatives should be included in creams. Cetrimide may cause irritation to the eye see Cetrimide.
