About Onerchemical

Onerchemical is a technical publication operated by Wuhan Oule Chemical Co., Ltd., a cosmetic-ingredient supplier based in Wuhan, Hubei. Our main supply operation is at onerchem.com; this site is a dedicated resource on cosmetic preservation science.

Why a separate site

Preservation sits at the intersection of microbiology, physical chemistry, and regulation — a field that deserves depth beyond what a supplier catalogue can offer. We publish here because the problems we hear from formulators (preservative-booster trade-offs, pH drift in challenge testing, cross-market labelling) call for essay-length answers, not product pages.

Who writes

All technical content is authored by Yang Ruosong, head of technical content at Onerchemical, with internal review by the manufacturing and QC teams before publication.

What we don't do

We publish no sponsored content, no vendor comparisons that aren't grounded in published data, and no fabricated reviews. We don't rank preservatives by anything other than what the chemistry and the regulation support.
