Boron nitride

Boron nitride (BN, CAS 10043-11-5) is an inorganic compound composed of boron and nitrogen atoms in a 1:1 ratio. It is sold under trade names including Borazon and Elbor and carries no assigned E-code. It has no E-code designation and is classified under HS code 28500012.

In personal care and cosmetics formulations, boron nitride functions as an antimicrobial agent, disrupting microbial cell membranes to inhibit bacterial and fungal growth and extend product shelf life. It is also evaluated in biotechnology and life sciences applications where controlled microbial suppression is required in biological media or surface coatings.

Boron nitride is available as a white powder in grades suited to cosmetic and technical applications. Suppliers operating within the EU must comply with REACH registration requirements. Procurement teams should confirm grade specifications and packaging formats directly with the supplier to match application requirements.
