What’s Alkyl polyglucoside (APG) ?

Alkyl polyglycosides are hemiacetal hydroxyl groups of glucose and fatty alcohol hydroxyl groups, which are obtained by losing one molecule of water under the catalysis of acid. It is a category of nonionic surfactant, it’s been widely used in a variety of daily chemicals, cosmetic, detergent and industrial applications. The raw materials are mainly extracted from palm and coconut oil so it is considered eco-friendly because of their complete biodegradation, this property makes almost no other surfactant comparable to it. So APG has been widely used in variety of filed.

2.The performance of APG applied in enhancing heavy oil recovery.  
Alkyl polyglucosides (APG) is a green surfactant with good interfacial activity, emulsification, foaming and wettability, and has the potential to improve heavy oil recovery under high temperature and high salinity conditions. The surface tension, interfacial tension, emulsion property, emulsion stability and emulsion droplet size of APG were studied. Also the effects of temperature and salinity on the interfacial activity and emulsifying properties of APG were studied. The results show that APG has good interfacial activity and emulsifying properties among all surfactants. In addition, the interfacial activity and emulsifying performance of APG are stable, and even became better with the increase of temperature or salinity, while the interfacial activity and emulsifying performance of other surfactants got worse to varying degrees. For example, at 90℃ with a salinity of 30 g/L, the oil recovery by using APG can reach up to 10.1%, nearly twice times higher than that ordinary EOR surfactant. The results show that APG is an effective surfactant for improving heavy oil recovery at high temperature and high salinity condition.

3.The properties of Alkyl polyglucoside(APG)
The functional attributes of Alkyl Polyglucoside(APG) surfactant,such as foaming,emulsification and bio-degradability.
Foaming: Alkyl polyglucoside surfactants are non-toxic, non-irritating, well compatible and have good foaming and surface activity. They are widely used in detergents and personal care products to promote foam formation.
