How to Choose Non-Toxic Clothing & Jewelry
1. What to Avoid in Clothing Fabrics
Synthetic fabrics like polyester, nylon, and acrylic are made from petroleum-based plastics and are often treated with chemical finishes. Conventional cotton is one of the most pesticide-intensive crops in the world. Wrinkle-resistant and stain-resistant finishes frequently use formaldehyde or PFAS (“forever chemicals”). Synthetic dyes without safety certification can contain heavy metals and azo compounds. Natural fibers — organic cotton, linen, wool, silk, and hemp — are the safest starting point.
2. What to Avoid in Jewelry Metals
Cheap jewelry is often made from unknown alloys that can contain nickel (a leading cause of contact dermatitis), lead (a neurotoxin with no safe exposure level), and cadmium (a heavy metal linked to kidney damage). Gold-plated and silver-plated jewelry can expose you to base metals as the plating wears off. Safest options are solid sterling silver (925), solid 14k or 18k gold, and verified nickel-free stainless steel.
3. Certifications to Look For
Oeko-Tex Standard 100 certifies that the finished textile has been tested for 100+ harmful substances. GOTS (Global Organic Textile Standard) certifies both the organic fiber content and the processing chain. For jewelry, look for brands that explicitly state their metals are nickel-free, lead-free, and cadmium-free — ideally with third-party testing to back it up.
