What is Bismuth Oxychloride?
Bismuth Oxychloride is a non-toxic, eco-friendly inorganic compound that appears as a silvery-white, crystalline powder with a pearlescent luster.
- Primary use: It is commonly used as a pearlescent agent in cosmetics.
- Other uses: It can serve as a pearlescent raw material in industrial applications, while high-purity grades may be used in medical imaging research.
We offer various grades of bismuth oxychloride, with customization available based on particle size and impurity specifications. We provide free samples, along with a Certificate of Analysis (COA) and Material Safety Data Sheet (MSDS) for every batch. Global shipping is available—we welcome your inquiries and orders.

Preparation Method for Bismuth Oxychloride
Produced via the hydrolysis of Bismuth Trichloride:
- Dissolve BiCl₃ in a dilute acid and adjust the pH to induce slow hydrolysis.
- Regulate the size and luster of the platelets by precisely controlling temperature, pH, and stirring speed.
- Subject the product to solid-liquid separation, washing, drying, and pulverization/classification.
- Classify by purity: cosmetic grade, industrial pigment grade, reagent grade, and high-purity nano-grade.
Application of Bismuth Oxychloride
Bismuth Oxychloride uses in cosmetics
Our cosmetic-grade BiOCl is suitable for:
- Eye products: eyeshadow, eyeliner, mascara
- Lip products: lipstick, lip gloss
- Face products: loose powder, pressed powder, foundation, blush, bronzer
It provides pearlescent luster and improves powder feel. Cosmetic-grade material is produced under stricter impurity control and meets regulatory safety requirements for leave-on and rinse-off color cosmetics.
Bismuth Oxychloride use in industrial
Our industrial-grade BiOCl functions as an environmentally friendly pearlescent filler:
- Plastics and masterbatch
- Automotive interior coatings
- Decorative coatings
- Printing inks
- Artificial pearls and decorative materials
BiOCl is also studied as a photocatalytic material due to its layered structure and internal electric field, which promotes charge separation.
Compared to the industrial grade, cosmetic-grade Bismuth Oxychloride is subject to stricter impurity controls and must meet regulatory safety requirements. Industrial-grade Bismuth Oxychloride, on the other hand, offers a cost advantage.
Bismuth Oxychloride has low oral bioavailability and low acute toxicity. When used within permitted concentration limits, cosmetics containing Bismuth Oxychloride are safe for most users; however, direct inhalation of the powder should be avoided when handling the raw material.
