Manufacturers of preparations may use an alternative chemical name for a substance (art. 14 ChemO):
a. if they demonstrate that disclosing the name of the substance on the label or in the safety data sheet would put the confidential nature of their business, in particular their intellectual property rights, at risk; and
b. if the substance meets the criteria specified in Section 1.4 of Annex I to the CLP Regulation.
The alternative chemical name shall be a name that identifies the most important functional groups or serves as an alternative designation.
Manufacturers wishing to use an alternative chemical name must make a request* (art. 15 ChemV, fee: 400 CHF) in writing to the Notification Authority.
The use of an alternative chemical name may be requested for a preparation:
a. in a specific composition;
b. with a specific trade name or a specific designation; and
c. reserved for certain uses.
Authorisation to use an alternative chemical name is granted to the manufacturer and is non-transferable.
During the first six years after the registration, declaration or notification of a new substance, there is no need to deposit a request to use an alternative chemical name. After that period, the chemical name pursuant to art. 18 (2) CLP must be used, or a request to use an alternative chemical name must be submitted.
