Usage Restrictions

SCA campaigns for mandatory restrictions of synthetic colour additives (excluding iron oxides) including food dyes, FD&C colours and carmine (cochineal or carmine extract) used in cosmetics and personal care products, especially eye makeup and lip products; SCA endorses products with the Allergy Certified logo that restrict the use of synthetic colours, including carmine, to a maximum of <1% or less for leave on products and a maximum of <3% or less for rinse off products. Colour additives should also require a warning on the product label to "always patch test before use" and "discontinue use if irritation occurs" - The EU and FDA has banned the use of many colour additives in products applied to the eye area >

Where a brand tests their products and/or the ingredient of concern is tested for carcinogenic contaminants, test reports confirming that the product and/or ingredients are free-from carcinogens can be submitted; SCA will endorse product(s) containing toxic-free colour additives with unrestricted usage provided proof of testing is provided. (Brands have 12 months to comply with SCA's terms effective as of 4th April, 2019 or discontinue use of SCA's Allergy Certified seal).
