About Certifications:
The OEKO-TEX certification process tests textiles and leather products for over 300 harmful substances to ensure consumer safety and environmental responsibility. It screens for heavy metals (e.g., lead, cadmium), formaldehyde, phthalates, pesticides, azo dyes, flame retardants, and polycyclic aromatic hydrocarbons (PAHs). The testing also covers substances regulated by laws like EU REACH and California Proposition 65, along with allergens (e.g., nickel, disperse dyes), volatile organic compounds (VOCs), and residual solvents. Products intended for babies or direct skin contact are subjected to stricter limits. The substance list is updated annually based on scientific findings and regulatory changes, ensuring compliance with global safety standards.
Greenguard Gold Certification is a third-party certification program that ensures products meet rigorous standards for low chemical emissions, contributing to healthier indoor environments. The certification involves comprehensive testing, including laboratory-based testing and modeling of indoor concentrations, to ensure products emit extremely low levels of volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs). With a focus on health-based criteria, Greenguard Gold Certification provides assurance that products meet strict standards for indoor air quality, protecting human health, particularly for vulnerable populations. The certification is widely recognized across industries, including furniture, building materials, healthcare, and education, and allows products to bear the Greenguard Gold logo, providing consumers with confidence in the product’s low chemical emissions and contribution to a healthier indoor environment.
