This paper describes the differences between alkyl polyglucosides (APG) of natural alcohol and oxo‐alcohol. The same reaction rate was observed for the one‐step synthesis of APG from branched alcohols and from linear alcohols. Biodegradation studies showed that the primary biodegradability value of natural C 8–10 APG was slightly higher than for oxo‐C 10–11 APG, and there was no significant difference between oxo‐C 12–13 APG and C 12–14 APG. The primary biodegradability value of oxo‐C 14–15 APG was lower than the four APG already named. The goal of this study of the physicochemical properties of these APG of natural alcohol and oxo‐alcohol was to evaluate their differences. Diversification of APG selection will help improve its physicochemical properties and expand its application fields. The results are that the wetting abilities of oxo‐C 10–11 APG and oxo‐C 12–13 APG are better than the natural alcohol C 8–10 APG and C 12–14 APG, whereas the foamabilities of oxo‐C 10–11 APG and oxo‐C 12–13 APG are worse than those for natural C 8–10 APG and C 12–14 APG. There are no real differences in surface tension and detergency between APG of natural alcohol and oxo‐alcohol.
