How the BULKING function is used in CosIng

The BULKING function is assigned by the European Commission in the CosIng ingredient inventory. This page currently lists 206 ingredients carrying that function label in the dataset, which helps you move from a functional claim to the exact ingredients that use it.

Non-reactive (chemically inert), solid ingredients that dilute other solids and/or increase the volume of cosmetic products.

Function assignments come from official EU CosIng data. They describe intended cosmetic use, but they do not replace regulatory review of each linked ingredient and any annex records tied to it.

Frequently asked questions

The BULKING function, as defined in the EU CosIng database, describes the role this group of ingredients plays in a cosmetic formulation. There are currently 206 ingredients in the EU CosIng inventory assigned this function. Function labels are standardised terms used in Product Information Files (PIF) and ingredient declarations.

Yes. An ingredient's function in the CosIng inventory is independent of its regulatory status. An ingredient with the BULKING function may also be listed in Annex II (prohibited), Annex III (restricted), or other annexes. Always check each ingredient's annex records for applicable conditions before formulating.

Ingredient functions are documented in the Product Information File (PIF) as part of the cosmetic product safety assessment. They describe the intended role of each ingredient in the formulation and support the safety assessor's review. Functions do not appear on consumer-facing product labels, which list only INCI names.
