Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 921-820-3 | CAS number: -
Categories
- Category name:
- acetalization products between glucose and Acetalization products between glucose and C12/22 (even numbered)-alcohol
Justifications and discussions
- Category definition:
- The category is built with substances of Unknown or Variable composition, Complex reaction products or Biological material (UVCB substances). The substances in this particular category are composed of fatty alcohols with mono and di-glucoside, called alkylpolyglucoside . Each category member is, at least, composed of one fatty alcohol and one alkylpolyglucoside with the same carbon chain length.
- Category description:
- The category is composed with UVCBs with increasing chain length.
- Category rationale:
- The category is built with substances of Unknown or Variable composition, Complex reaction product or Biological material (UVCB substances). The substances in this particular category are consisting of fatty alcohols (even numbered) with mono and di-glucosides, called alkylpolyglucosides. Each category member is manufactured from fatty alcohol and glucose. All the members of this category are either mixture of fatty alcohols reacted with glucose or blends of alkyl glucosides of various chain lengths and degrees of polymerization.
The alcohols are saturated linear compounds with a chain length of 12 to 22 carbons (even numbered), and the alkylpolyglucosides are formed of a hydrophobic carbon chain, with the same length, linked to one or two glucoses. The polymerization rate is close to one (1.2 to 1.5) The above mentioned UVCB substances can be considered as a category because the constituents are very closely related and thus can be treated similarly. Actually, the fatty alcohols results from natural sources (i.e. primarily edible food crops) or from reproducible synthetic source.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
