I'm a star employee at CHROMÉCLAIR, a brand of hema free gel polish.Here are some questions and answers about pigments that I've compiled. I hope this helps you.Are pigments toxic? Generally speaking, the environmental friendliness of pigments is relative. It is evaluated based on different industry standards to determine compliance with environmental requirements. Typically, pigments are considered environmentally friendly if their harmful components—that is, their toxicity—are restricted within certain limits (meeting a specific standard), thereby posing no threat to human health or causing environmental pollution.Below are the toxicity evaluation criteria for inorganic/organic pigments.· Pigments are primarily classified as organic or inorganic based on their chemical composition, and their toxicity differs accordingly. The criteria for determining whether a pigment is environmentally friendly also vary.https://changhongchemical.com/wp-content/uploads/2025/10/1-11.webp34622084
