천연계 비이온 계면활성제 APG(Alkyl Polyglucoslde)는 옥수수 성분의 글루코스와 팜, 야자유에서 얻어지는 지방 알코올을 이용하여 합성된다. 친수성인 글루코스의 중합도(D.P.=1.2~1.8)와 소수성인 alkyl chain 길이 (C8-C14)에 따른 계면특성(표면 계면장력, cmc, 기포력, effectiveness 등)을 조사한 바 중합도에는 영향이 적으나, alkyl chain 길이에는 큰 영향을 받았다. 지방산 오염에 대한 APG alkyl chain 길이별 세정력 평가를 한 결과 계면 장력이 낮을수록, 단위 면적당 흡착량이 많을수록 우수한 세정력을 나타내었으며, 그 순서는 APG 0814> APG 1214> APG 10> APG 0810> APG 08과 같다.

Alkyl polyglucosides (APG), so called natural nonionic surfactants, are prepared with glucose from corn starch and fatty alcohol from palm and/or coconut oil. When we studied on interfacial properties of APG, surface and interfacial tension, cmc, foaming and effectiveness, according to degree of polymerization of glucose unit (D.P.=1.2~1.8) and alkyl chain length, the former hardly affects but the latter greatly affects on them. The order of detergency for fatty acid soils decreased as followings ; APG 0814> APG 1214> APG 10> APG 0810> APG 08, and the samples with lowest interfacial tension and maximum adsorption had a better detergency.
