Understanding Chemical Mixing Services
Chemical mixing, also called toll mixing, is an essential process across industries like pharmaceutical, cosmetics, food production, minerals, and plastics.
It involves techniques such as batch mixing, chemical blending, emulsification, particle size reduction, paste mixing, and homogenisation to achieve a customised blend suited to your individual business needs.
ReAgent has been providing bespoke chemical mixing services in the UK for almost 50 years. With decades of experience, we’ve worked with a wide range of clients from small businesses to large-scale companies, and have earned a reputation as one of the most trusted companies in the chemical industry.

Our Bespoke Chemical Mixing Process
Because we’ve been manufacturing chemicals since 1977, you can trust us with any chemical mix your business may require. From corrosive acid to flammable liquid, we have an extensive range of chemicals and equipment to create the perfect formula for you.
Plus, we offer full-spectrum services, from formulation through to delivery, and all steps in between, helping take the stress of production off of your shoulders.
Here’s a breakdown of all the different aspects.
Formulation
We collaborate with you to create custom formulations and mixing solutions that meet your exact specifications. Using advanced filtration processes - down to as little as 0.2 micron - we help ensure superior product quality. Rigorous chemical analysis and testing alongside this process also guarantees compliance with all relevant regulations and standards.
Blending
Our chemical blending services cover a wide range of needs, including pre- and post-treatment of blends, power blending and blends at elevated temperatures. For thicker substances, our high viscosity blenders handle materials up to a viscosity of approximately 50,000cP. This means that, whether you need antifreeze or caulking compound, we’ve got you covered.
Filling and capping
From 1ml ampoules to large 1000L IBCs and everything in between, we cater to a variety of filling requirements. With specialist in-house equipment such as gravity fed, pump-fed bottle filling equipment, semi-automatic filling, and volumetric filling machines, your products will be precisely and efficiently measured for every batch.
Labelling
Our customisable labelling service means we can supply your products in fully-branded packaging so that they’re ready to go. You can either supply us with your own design, or we can create a bespoke label for you with all your company’s details. We also use durable laser print polyethylene to make our labels, guaranteeing the best quality for every bottle.
Dispatch
To ensure your products get where they need to go, we only use ADR-registered couriers to ensure the safe transport of your chemicals to anywhere in the world. Delivery tracking services are also available so that you can follow the progress of your order, whether that’s to your facility or directly to your customers.
