Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

(a) Category members subject to the REACh Phase-in registration deadline of 31 May 2013 are indicated in bold font. Only for these substances a full set of experimental results and/or read-across is given.
(b) Substances that are either already registered under REACh or not subject to the REACh Phase-in registration deadline of 31 May 2013 are indicated in normal font. Lack of data for a given endpoint is indicated by “--“.
(c) Surrogate substances are either chemicals forming part of a related category of structurally similar fatty acid esters or precursors/breakdown products of category members (i.e. alcohol and fatty acid moieties).Available data on these substances are used for assessment of (eco)toxicological properties by read-across on the same basis of structural similarity and/or mechanistic reasoning as described below for the present category.
(d) Assessment of toxicological properties is conducted also taking into account available data on mixtures of synthetic and/or naturally occurring glycerides (e.g. vegetable oils), which cannot be identified by a (single) CAS/EC number.The test materials short-, medium- and long-chain triglycerides (SCT, MCT, LCT) and their combinations (e.g. MLCT, SALATRIM – a SLCT) comprise triesters of glycerol with fatty acid chain lengths of C2 and C4 (short-chain), C8 and C10 (medium-chain) and C18 saturated/unsaturated (long-chain). The substance “mixture of mono-, di-, and triglycerides of lauric acid” comprises mono-, di and triesters of glycerol with dodecanoic acid (C12). The substance “Modified triglyceride” contains main components: 1,3-dioleoyl 2-palmitoyl triacylglycerol and 1,2-dipalmitoyl 3-oleoyl triacylglycerol, comprising triesters of glycerol with hexadecanoic (C16) and (9Z)-Octadec-9-enoic acid (C18:1). Available data on identity and composition of the individual test material for a given study is provided in the technical dossier.
*) The substance was preregistered with CAS 97593-30-1 / EC 307-333-3, Glycerides, C8-21 and C8-21unsatd. mono. and di-, acetates. During analytical specification process the more appropriate CAS 91744-35-3 / EC 294-597-7, Dodecanoic acid, ester with 1,2,3-propanetriol, acetylated was found. Therefore, the substance will be registered as CAS 91744-35-3.
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).
