Restricted Substances in Cosmetics
Certain substances are restricted or prohibited from being used in cosmetic and personal care products. Restricted substances analysis or Traces and Impurities testing is important to ensure that their presence ensures cosmetic safety, efficacy, quality and provides cosmetic compliance.
To assist ensure cosmetic compliance with regulation EU No1223/2009, QACS Labs conduct cosmetic testing & personal care testing services on Traces and Impurities under optimal scientific practices using state-of-the-art equipment. Among the substances that QACS is GMP accredited for are Heavy Metals, Impurities, Nitrosamines, Allergens, and Residual solvents. Traces and Impurities testing from QACS includes Heavy metal testing, Impurity testing, Nitrosamine testing, Allergen screening, Formaldehyde testing, Residual solvents testing, Preservatives testing, PAHs and Phthalates testing.
- Arsenic (As)
- Lead (Pb)
- Chromium (Cr)
- Cadmium (Cd)
- Cobalt (Co)
- Nickel (Ni)
- Phthalates testing
Αdditives to increase the flexibility of plastic, often found in cosmetic and personal care products. Packaging Testing services for cosmetics are provided, to detect chemicals (plasticizers) used in products. Safely support product claims by proceeding to Packaging compatibility for cosmetic and personal care products.
- 1,4-Dioxane analysis
Synthetic industrial chemical categorized as probable human carcinogen, byproduct of the manufacturing process of certain cosmetic ingredients (detergents, foaming agents, emulsifiers and solvents). We perform Dioxane testing to meet regulatory needs.
Acrylamide detection in personal care products
Furocoumarins detection in personal care & cosmetic products
Formaldehyde can be found in shampoos, hair gel, eyelash glue, hair smoothing products, liquid baby soaps and more. At QACS we perform Formaldehyde testing for cosmetics.
- PAH’s testing -Polycyclic Aromatic Hydrocarbons
N-nitrosamine Detection and Quantification for cosmetic and personal care products are provided.
Nitrosamines formation in cosmetics derives from the reaction between amines and amino derivatives in the presence of nitrosating agents forming harmful and possible carcinogenic substances such as NDELA (N-nitrosodiethanolamine). The European limit of 50 ppb for nitrosamines should apply to raw materials as well as to finished products containing Nitrosamines. N-nitrosamine impurities in cosmetics might be found in products like hair dyes, nail varnishes etc.
Substances or mixtures present in fragrances or cosmetic products from naturally derived ingredients, pose allergen risks. Allergic reactions such as contact dermatitis can induce skin sensitization. At QACS, we perform Allergen Testing for cosmetics and personal care products. Method of analysis stays in line with the existing regulatory framework of EC Reg 1223/2009, SCCS 1459 and ‘2012 Opinion’.
