The CEPRA laboratory performs analyzes on the main preservatives (parabens, mit, phenoxyethanol ..) used in cosmetic products, in order to verify that the concentration limits imposed by Annex V of Regulation 1223/2009 are respected.
PARABEN ANALYSIS:
| Methylparaben (CAS: 99-76-3) |
MAXIMUM ALLOWED CONCENTRATION: 0.4% (in acid) for a single ester 0.8% (in acid) for ester mixtures |
| Ethylparaben (CAS 120-47-8) |
MAXIMUM ALLOWED CONCENTRATION: 0.4% (in acid) for a single ester 0.8% (in acid) for ester mixtures |
| Propylparaben (CAS: 94-13-3) |
MAXIMUM ALLOWED CONCENTRATION: 0.14% (in acid) for the sum of the individual concentrations 0.8% (in acid) for mixtures, to the extent that the sum of the individual concentrations of propylparaben and butylparaben and their salts does not exceed 0.14%. OTHER LIMITATIONS AND REQUIREMENTS: Not to be used in leave-on products intended to be applied in the diaper area of children under the age of three. |
| Butylparaben (CAS: 94-26-8) |
MAXIMUM ALLOWED CONCENTRATION: 0.14% (in acid) for the sum of the individual concentrations 0.8% (in acid) for mixtures, to the extent that the sum of the individual concentrations of propylparaben and butylparaben and their salts does not exceed 0.14%. OTHER LIMITATIONS AND REQUIREMENTS: Not to be used in leave-on products intended to be applied in the diaper area of children under the age of three. |
Benzylparaben (CAS: 94-18-8) is prohibited in cosmetic products (Annex II, item 1377)
MIT ANALYSIS
| Methylchloroisothiazolinone (CAS: 26172-55-4) |
MAXIMUM ALLOWED CONCENTRATION 0.0015% (of a 3: 1 mixture of methylchloroisothiazolinone and methylisothiazolinone) in the rinse products |
| Methylisothiazolinone (CAS: 2682-20-4) |
MAXIMUM ALLOWED CONCENTRATION 0.0015% (of a 3: 1 mixture of methylchloroisothiazolinone and methylisothiazolinone) in the rinse products 0.0015% in rinsing products NB: the two conditions are mutually exclusive. The use of methylisothiazolinone mixed with methylchloroisothiazolinone is not compatible with the use of methylisothiazolinone alone. |
