Allergies to wheat and peanuts are generally known in food products. However, skin contact with these substances can also lead to the development of corresponding allergies. For this reason, the EU has regulated the use and quality of wheat proteins and peanut oils.

Regulation (EU) 2017/2009 amending Annex III of the EU Cosmetic Regulation defines limits for these ingredients. From September 25, 2018, cosmetic products placed on the market must meet the aforementioned requirements.
Peanut oils used in cosmetics may only contain a maximum concentration of 0.5ppm of peanut proteins. The restriction for hydrolyzed wheat proteins depends on the average molecular mass of the peptides. The maximum value for the average mass is 3.5 kDa.
