CLP classification: distinguish the evidence

Reference hazard classes in the source dataset: Skin Corr. 1C; Eye Dam. 1. Identified statement codes: H314, H318, EUH071. These codes do not classify a mixture.

Harmonised classificationVerify the exact Annex VI entry, including notes, physical form and scope.Other classification dataRegistrations, notifications and supplier SDSs must not be presented as harmonised classification.

SCL, ATE and M-factor

Use these values only after confirming substance identity, hazard class, route, units, form and the primary source. Numerical values are deliberately not published in this review edition.

Where the substance matters in an SDS

Depending on the product, substance data can affect Sections 2, 3, 7, 8, 9, 10, 11, 12, 14 and 15. Reactivity and incompatible materials must be taken from data relevant to the supplied grade and final mixture.

Essential distinction

A CAS number does not automatically classify a product

The classification of a mixture containing Lactic acid depends, among other factors, on concentration, physical form, impurities, applicable limits, mixture properties and product-specific supplier data.
