Oleamidopropyl betaine is a new type of special amphoteric surfactant. It belongs to the same series as lauroamidopropyl betaine, and both are modified derivatives of alkyl betaine. Oleic acid amidopropyl betaine has the characteristics of temperature resistance, acid and alkali resistance, good salt resistance, wide isoelectric point, and strong viscoelasticity. It is widely used in oilfield flooding, leather, daily chemical industry and other fields. As a good viscoelastic surfactant used in the acidification of the oilfield matrix, it can effectively reduce the oil/water interfacial tension and improve the tertiary oil recovery. In addition, it can be used as a conditioning agent, wetting agent, bactericide, antistatic agent, emulsifier, thickener, and self-returning acid system for hydrochloric acid carbonate.


It has washing, conditioning, antistatic and bactericidal effects. It is used in the preparation of shampoos, bath agents, facial cleansers, baby detergents; enzyme preparations. It is widely used in cheese manufacturing, and also used in the manufacture of coagulated casein and curd pudding. The amount depends on the production needs. The general dosage of powder is 0.002%~0.004%, first dissolve it in 2% salt solution for use.

Amphoteric surfactants are surfactants that contain both anionic hydrophilic groups and cationic hydrophilic groups in the same molecule. Amphoteric surfactants usually have good washing, dispersing, emulsifying, sterilizing, soft fiber and antistatic properties, and can be used as fabric finishing aids, dyeing aids, calcium soap dispersants, dry cleaning surfactants and metal corrosion inhibitor Wait. However, the price of this type of surfactant is more expensive, and the practical application range is smaller than other types of surfactants. "Amphoteric Surfactants" on ECHEMI mainly supplies chemicals for amphoteric surfactants.
