Today alkyl poly glycosides are a typical ingredient in many cosmetics and in lightweight dishwashing formulations. Cognis (formerly Henkel) is the largest European producer with 25,000 tons capacity installed followed by Lamberti, SEPPIC and Akzo Nobel.

Personal Care Products The extremely low interfacial tension of microemulsions versus oil makes them very good candidates for the development of efficient cleanser formulations. Studies have been made using microemulsions for make-up cleanser applications (73), as skin cleansers to remove dirt and sebum from the skin (74), and the use of alkyl poly glycosides were shown to have excellent environmental and skin compatibihty (75) For topical cleanser applications, the flow properties are important. A formula based on... 

The surface tension of alkyl (poly)glycosides was investigated as a function of the alkyl chain and the degree of polymerization (DP) using samples differing in composition. In addition to pure surfactants for characterizing the basic depen-... 

Spectrum of supplementary effects [45-47], With regard to foam, alkyl poly glycosides are comparable to betaines and sulfosuccinates and can stabilize the foam of anionic surfactants in hard water and in the presence of sebum. The broad spectrum of applications in the personal care field is summarized in Table 4.6.

Unlike the system with GMO, the formation of a broad microemulsion phase is not observed in the whole temperature range for the phase inversion in the model emulsion containing glyceryl monoisostearate (GMI) (Fig. 7) [10]. Instead, a finely dispersed bluish emulsion is formed at an alkyl poly-glycoside/GMI ratio of about 2 1. A transparent microemulsion can be observed only at temperatures above 50°C. The phase inversion concentration ratio does not vary with temperature. 

The phase behavior of the emulsifier system with fixed oil and water contents is shown in Fig. 10. A microemulsion is formed at a GMO concentration between 15 and 25% of the total emulsifier system with C12/14 alkyl polyglycoside/Cg/ro alkyl polyglycoside in a suitable mixing ratio. The necessary amount of GMO differs only slightly from the optimal alkyl poly-glycoside/GMO ratio that was found in the simple model emulsion as discussed earlier.
