- Additional information:
Information on the skin sensitization potential of technical enzymes was summarized by the Enzyme REACH Consortium (ERC) [1]. The skin sensitization potential of enzymes has been reviewed in several publications [1-8], revealing that enzymes should not be considered skin sensitizers. In addition, there is an unequivocal statement from AMFEP (www. amfep. org) on this topic showing that enzymes do not have skin sensitizing potential. The lack of skin sensitizing potential is substantiated by evidence from robust human experimental data and extensive in-use human studies performed with detergents containing enzymes [1, 9-13, 14-19]. All of these studies confirmed that the presence of enzymes in the detergents did not result in contact skin sensitization, including those conducted with atopic individuals.

Respiratory sensitisation
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (sensitising)
- Additional information:
Enzymes regardless of the catalytic activities are potential respiratory allergens, whereas the weight of human evidence indicates that enzymes are not skin sensitizers [1]. All enzymes must therefore be classified as respiratory sensitizers [2], “H334: Hazard Category 1: May cause allergy or asthma symptoms or breathing difficulties if inhaled” in accordance with the CLP Regulation [1].
There is no animal model available to test and rank respiratory sensitisers. Based upon the currently available information including human data collected for over 40 years it is concluded that potency sub-categorisation for respiratory sensitisers is premature and can potentially be misleading, therefore enzymes should be classified as Respiratory Sensitizer Category 1[1, 3].
Since enzymes are considered repiratory allergens, a DMEL (Derived Minimum Effect Level) for workers and consumers have been established [4, 5].

Justification for classification or non-classification
Non- protease enzymes such as β-fructofuranosidase are not considered to be skin sensitizers, but there is evidence that enzymes are a respiratory sensitisers. Therefore, β-fructofuranosidase is concluded to be a Respiratory Sensitizer Category 1 according to Regulation (EC) No. 1272/2008 (CLP).
