High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
At Deqing Demi Pigment Technology Co., Ltd., we prioritize environmental stewardship and product safety. Our environmentally compliant range is designed to give manufacturers peace of mind in an increasingly regulated global market. We invest in rigorous testing and quality control to ensure that our pigments meet the highest standards of safety. We work with clients across industries to provide materials that are as safe for the user as they are for the planet, without compromising on color performance.
| Contaminant | Typical Level | Regulation Limit |
| Lead (Pb) | < 10 ppm | RoHS / REACH |
| Cadmium (Cd) | < 1 ppm | RoHS / REACH |
| Mercury (Hg) | < 1 ppm | RoHS / REACH |
| Hexavalent Cr | < 5 ppm | RoHS / REACH |
| Arsenic (As) | < 5 ppm | REACH |
A: No, inorganic pigments are mineral-based and do not biodegrade. However, they are chemically inert and do not leach harmful substances into the environment.
A: Yes, we provide third-party testing reports (e.g., from SGS or Intertek) to verify the compliance of our pigments with specific international standards.
Our quality control process includes ICP (Inductively Coupled Plasma) testing for every production run of compliant grades. This allows us to detect trace metals at the parts-per-million level.
Transparent Documentation: we provide a comprehensive compliance pack for our customers, including declarations of conformity and detailed chemical analysis, supporting their own internal safety audits.
In environmentally compliant pigments, color science must be balanced with chemical purity. Removing certain trace metals can sometimes affect the hue; however, we utilize precision synthesis to maintain a high level of chroma (C*). We use spectrophotometric data to ensure that our compliant grades are indistinguishable in color from standard grades, allowing our customers to transition to safer materials without having to change their existing color formulations or brand standards.
