Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information
The category of C12-22 alkyl polyglucoside 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 of substances included in this category are saturated linear compounds with a chain length from 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 1 (1.2 to 1.5).
The starting material 12-hydroxystearic alcohol is composed of saturated linear alcohols with a chain length of 18 carbons and thus falls into the category.
Log Koc ranges from 2.4 to > 5.63 for the 6 other members of the category. A log Koc of > 5.63 has been established for one member of the category with C16 -18 alkyl chain. This value of Log Koc represents the worst case value for all members of the category.
Therefore, the value of Log Koc > 5.63 can been taken for the substance acetalization product between glucose and 12 -hydroxystearyl alcohol.
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.
