Definition "Component Category" - UN GHS -Regulatory Conten Documentation

Hello everybody,

I have a question according the definition "Component category". Can somebody explain me the term „Component category“?

I found this term in der Document "GHS_V5-1 - GHS Version 5.1 – Functional Description" (Regulatory Content - August 2016) on page 17:

But I have no clue what the component category is. Is it similar to the "Component Type"? Where can I maintain it? In the CG02 "Substance Workbench"?

Thanks for your advice.

    Dear Melanie

    I assume the term tries to "mix" something.

    1:) one part is the component type

    2.) second part. for composition you might use e.g. "PURE_SUB" / "LIST_SUB" etc.

    Normally neither the "component type" nor the spec type is relevant for using a rule set.

    Not a very good term.


    PS: For composition: you can use as well "Exeption value". Up to know: I do not know "good" uses of this values as part of composition. To my knowledge: Exception value is not used in a "Rule set"

    Hello Melanie,

    The component type is a value that you can enter in the "Composition Tab" to specify what "role" a certain component plays in your composition. This is meant by the term component category.

    The following values are possible:

    ACT_AGENT Active ingredient ADDITIVE Additive ADJUVANT Auxiliary agent CATALYST Catalyst CONFIDENT Confidental component EMULSIFIER Emulsifier IMPURITY Impurity INGREDIENT Ingredient INHIBITOR Inhibitor INTADDED Intentionally Added INTERLAC Surface-active agent MONOMERE Monomer PRESERV Preservative PRODUCT Product SOLVENT Solvent STABILIZER Stabilizer TRIGGER Starter ZPH_API Active Pharmaceutical ingredient

    Some rule sets do not take certain component categories into account - or you can customize them to do so. Apparently the GHS rule set does not care.

    Kind Regards
