Part of the information provided below is based on information supplied to us by the material manufacturers. Essential information regarding product handling and the safety and health of users can be found in the Safety Data Sheet for each material.

Safety documentation and copies of the relevant certifications are kept at the .bijouets production facility. Anyone wishing to verify the characteristics of the materials may request the relevant documentation by contacting us at bijouets@bijouets.com.

Manufacturing materials

PA11 and PA12 are recyclable polyamides. We mainly use natural polyamide PA11, complemented, for some products and colours, by recycled polyamide PA12. Both materials offer lightness, strength and quality.

PA11 - Natural polyamide

A bio-based material derived from the castor plant, used in additive manufacturing processes (Laser Sintering).

Biocompatibility and safety

The material has undergone biocompatibility testing in accordance with international standards. The tests assessed cytotoxicity, irritation and sensitisation and, under the test conditions, showed no cytotoxic, irritating or sensitising effects. The material also complies with the requirements of the European REACH Regulation concerning the registration, evaluation and control of chemicals. Based on the information available, it does not contain SVHCs above the thresholds established by the Regulation.

PA12 - Recycled polyamide

A partially recycled polyamide powder used in additive manufacturing processes (Laser Sintering).

Biocompatibility and safety

The material has undergone biological testing for cytotoxicity, irritation and sensitisation. Under the test conditions, no cytotoxic, irritating or sensitising reactions were observed. The material also complies with the requirements of the European REACH Regulation. Available data also indicate compliance with USP Plastic Class VI requirements.

Materials used for surface treatments

The pigments used for colouring are not classified as hazardous or toxic. No hazardous decomposition products are known. The products are not subject to labelling requirements under EEC Directive No. 1907/2006.

Additional materials

Earrings are made of hypoallergenic, nickel-tested silver; necklaces with metal structures use gold-plated brass wire; sunglasses are fitted with CR39 lenses produced by Carl Zeiss Vision Sunlens. All metal components that come into contact with the skin are made of hypoallergenic materials.

Mechanical performance

The technology used may be subject to unpredictable variations in operating parameters, which means that some products may occasionally not meet the expected mechanical characteristics. For this reason, the manufacturer carries out validation tests on randomly selected products. It is understood that rigorous and absolute quality control cannot be guaranteed. Should the purchaser identify a breakage of uncertain origin, the manufacturer may replace the product with an equivalent one, following any necessary technical assessment based on photographic evidence or direct examination of the defective product.

Material disposal

PA11 and PA12 are recyclable polyamides. Waste and production scraps that, for technical reasons, cannot be directly reused are sent for recycling by the manufacturer. Residues resulting from the colouring process are managed in accordance with applicable regulations and transferred to certified and authorised waste disposal companies.
