  • Methylparaben (CAS 99-76-3)

The data shall be submitted via email to [email protected]; the deadline for submission is 15 December 2023.

CTPA submission of data

As part of its liaison with Cosmetics Europe, CTPA is assessing which ingredients have industry dossiers available and if so, to seek submission of these dossiers to OPSS.   However, individual companies are encouraged to also submit data supporting the safety of any ingredients in the Call if these are avaialble. 

Note on data submission

Default Bodyweight

It is important to note that the UK Scientific Advisory Group on Consumer Safety (SAG-CS) has recently changed the default body weight for risk assessment to 70kg to be more representative of UK population.

Data on children or pregnant women

OPSS also notes that if these ingredients will be used in products that may foreseeably be used by children or pregnant women, relevant data to support the safety and exposure estimates should be provided for these populations.
