A materials supplier built around formulation reality
ZINWISE is the zinc oxide materials brand of Zhongshan Pinzhi Biotechnology Co., Ltd. We supply zinc oxide to cosmetic formulators and industrial manufacturers, with documentation that survives procurement review.
Why we exist
Zinc oxide is not a difficult material to source. It is difficult to source consistently. A formulator who qualifies a grade, builds a formula around it, and files a registration cannot absorb a supplier whose particle size drifts between lots or whose paperwork arrives three months late.
Most zinc oxide on the market is sold as a commodity with a spec sheet and not much else. We take the opposite position: the product is the material plus the reproducibility, the documentation, and the technical support that let a customer actually use it.

How the supply chain is structured
We work with an upstream materials partner for zinc oxide supply and a contract manufacturing partner for processing. This structure lets us concentrate on what determines whether a customer stays: specification control, batch documentation, and technical response time.
Upstream material
Zinc oxide sourced through an established materials partner with defined incoming specification.
Processing
Contract manufacturing with controlled precipitation, calcination, and surface treatment stages.
Quality & documentation
Cross-method particle characterisation and per-lot certificates of analysis.
Partner names and facility details are available to qualified buyers under NDA. We do not publish supply-chain partner identities without their consent.
What we hold ourselves to
No unverified numbers
If a parameter has not been measured for the exact grade, we say so rather than quoting a typical value and letting you discover the difference later.
Documentation before shipment
A lot does not ship without a certificate of analysis. Technical and safety data sheets are available before you commit to a trial.
Regulatory honesty
We state the listing status per market rather than implying universal approval. Your registration team should never be surprised by a filing gap.
Responsive technical contact
Formulation questions get answered by someone who understands the material, not forwarded into a queue.
