The requirement is described in CLP as follows:
3.1.3.6.2.2. In the event that a component without any useable information for classification is used in a mixture at a concentration ≥ 1 %, it is concluded that the mixture cannot be attributed a definitive acute toxicity estimate. In this situation the mixture shall be classified based on the known components only, with the additional statement on the label and in the SDS that ‘x per cent of the mixture consists of component(s) of unknown acute toxicity’, taking into account the provisions set out in section 3.1.4.2.
4.1.3.6.1. In the event that no useable information on short-term (acute) and/or long-term (chronic) aquatic hazard is available for one or more relevant components, it is concluded that the mixture cannot be attributed to one or more definitive hazard category(ies). In this situation the mixture shall be classified based on the known components only, with the additional statement on the label and in the SDS that: ‘Contains x % of components with unknown hazards to the aquatic environment’
This concept is part of UN GHS, i.e. it applies to all legislations. While acute (human) toxicity uses ATE values, aquatic toxicity does not. Thus we implement this as follows:
We have implemented unknown human toxicity which is relevant for classification, but not the counterpart for ecological hazards. This needs to be added.
