About

Built to be your qualified second source

Vista Emulsion is the international brand of Longyan Weishida Chemical Co., Ltd., a specialty chemical trading and export company established in 2022 in Longyan, Fujian, China. The brand covers a focused range of industrial-grade nonionic emulsifiers — sorbitan esters and PEG esters — backed by a production base with an annual capacity of 20,000 tons. We handle international sales, export delivery and project communication, with production, batch quality control and technical depth secured at the manufacturing side.

Our model is deliberately conservative: we do not ask formulators to replace a proven supplier overnight. We help you qualify a second source properly — with samples, TDS, SDS, COA, batch records, manufacturer authorisation and parallel test plans — so that when you shift volume, it is a data-driven decision, not a gamble.

What you can expect

Documentation first. TDS, SDS (GHS/transport), recent-batch COA and manufacturer authorisation before you test.
Targeted sampling. 2–3 sample routes matched to your system — never a blind catalogue.
Honest compliance dialogue. Destination-specific regulatory confirmation before any commitment (e.g. REACH pathways in Europe).
Total-cost comparison. We quote and compare on dosage, delivered cost and validated performance — not just price per kg.
Flexible commercial terms. Samples, first orders, packaging and staged supply arrangements are all discussable.

Where we work

Priority regions: Southeast Asia · Middle East · Latin America · Africa. European projects proceed once the REACH responsibility pathway (importer / OR) is confirmed. Products are currently sold as industrial-grade raw materials; food, cosmetic, pharma or pesticide-formulation uses require separate confirmation.

Quality control

How every batch is controlled

Incoming raw materials are inspected against specification before release to production.
In-process control during esterification: acid value, saponification value and appearance are monitored against the grade specification.
Batch release testing — every production batch is tested and issued its own Certificate of Analysis before packing.
Retained samples and traceability — batch samples are retained, and every drum is traceable to its production record.

Packaging & delivery

Getting product to your plant

Packaging

25 kg and 200 kg drums as standard; IBC totes, custom packaging and tank truck supply on request. Drums are palletized and stretch-wrapped for container loading.

Shipping

FCL and LCL sea freight from Xiamen port, with export documentation handled in-house. Products are non-dangerous goods for transport.

Lead time

Samples ship within days; production orders are scheduled and confirmed at order placement, with batch COA issued before dispatch.

Sustainability

Practical responsibility, not slogans

Biodegradable chemistries

Our PEG ester emulsifiers (PEG-400/600 oleates and laurates) are biodegradable per the manufacturer's product documentation, and the sorbitan ester range is built on fatty-acid chemistry of vegetable origin — supporting customers formulating toward lower environmental impact.

Safe handling, documented

Every grade ships with a current SDS covering GHS classification and transport. Our products are non-flammable, non-explosive and transported as general non-dangerous goods, reducing handling risk across the supply chain.

Packaging that gets reused

Standard 200 kg steel drums and IBC totes are widely reconditioned and reused in destination markets; bulk tank-truck supply removes single-use packaging entirely for larger customers.

Honest compliance dialogue

We confirm regulatory status per destination market before making commitments — no blanket claims. Batch traceability and retained samples back every statement we make about a shipment.
