NPI-11301 is a highly efficient free radical photoinitiator with high initiation efficiency, low odor, low migration, and low toxicity. It exhibits low oxygen polymerization inhibition and good solubility, making it suitable for applications requiring direct human contact. Key uses include UV-curable coatings and inks for food packaging, with a recommended dosage of 3-5% by weight.
Introduction
NPI-11301 is a house grade developed for applications where the cured coating will be handled or will come into contact with people. Its stated profile is low odour, low migration and low toxicity, with low oxygen inhibition, which together point at food packaging inks and similar work.
It is also one of the grades for which we publish less than we would like. The chemical identity is confidential and is supplied under NDA rather than on the open data sheet, which is a deliberate commercial choice on our part.
Physical & Chemical Properties
Off-white powder. Purity ≥98.00%. Recommended dosage 3–5% by weight. Chemical name, molecular formula, CAS number, molecular weight and absorption wavelength are confidential and available under NDA.
Applications
UV-curable coatings and inks intended for food packaging and similar direct-contact applications, where low odour and low oxygen inhibition are the requirements. Recommended at 3–5%.
Regulatory status and what we can and cannot tell you
We cannot give you a CAS number for this grade on an open page, and without a CAS number neither of us can check it against the Candidate List, Swiss Annex 10 or the German Anlage 14. That is a genuine limitation, and it is the kind of thing that surfaces during a customer audit.
What we will do is straightforward: sign the NDA, disclose the identity to you and your regulatory adviser, and let you verify the position yourself. If a supplier offers you a confidentiality claim and a clean regulatory story without letting you check either, that combination is worth being suspicious of. Ask us and we will put the identity in front of whoever needs to see it.
Packaging
20 kg cartons. COA per batch, SDS in English under NDA where required.

Frequently Asked Questions
What is your minimum order quantity (MOQ)?
MOQ depends on the product and specification. For most chemicals we can supply from 1 kg sample orders up to full container loads (FCL). Contact us with the product name and CAS number for a specific MOQ quotation.
Can you provide samples before I place a bulk order?
Yes. Samples are available for most products — typically 100g to 1kg. Sample fees may apply for expensive products and are usually deducted from your first bulk order. We recommend independent testing of samples before committing to bulk.
What documents do you provide with each shipment?
Every shipment includes a batch-specific Certificate of Analysis (COA), MSDS/SDS, commercial invoice, packing list and bill of lading. Certificates of origin, REACH/SVHC declarations and third-party inspection reports are available on request.
What is your typical lead time?
Production usually takes 10–20 days depending on the product and quantity. Sea freight to most destinations takes 15–30 days; air freight 5–10 days for samples and small orders. Our five warehouses in China allow fast dispatch of stocked items.
What payment terms do you accept?
We commonly accept 30% deposit + 70% against copy of bill of lading, T/T bank transfer, and Letters of Credit (L/C) for larger orders. Payment terms are confirmed in writing before production starts.
Are you a factory or a trading company?
We are an integrated supplier with three in-house manufacturing plants, supported by five warehouses across China. This gives us direct control over production quality while maintaining a broad product range.
