Science at the heart of everything we make
Our in-house laboratory is where formulation expertise, ethical chemistry and fragrance knowledge come together. From compliance to creation, we do the science so your brand does not have to.
Expert chemistry.
Oxford-trained.
Our laboratory is led by a CEO with a chemistry degree from the University of Oxford. That academic foundation, combined with decades of applied manufacturing experience, shapes how every formulation is developed. Rigorous, evidence-based and commercially grounded.
Ethical from the ground up.
Every ingredient we source is REACH-registered, cruelty-free and selected with vegan and environmental principles in mind. We do not compromise on sourcing because the chemistry demands it. We choose suppliers who share our values and audit them to prove it.
Compliance that stays ahead.
We monitor regulatory changes across UK, EU and international markets as a matter of course. When legislation moves, we already know what is coming. Your products are not just compliant today. They are prepared for what the regulations require tomorrow.
We choose ingredients because they are right, not because they are available. Ethically sourced, cruelty-free and selected with the finished product and the planet in mind. That standard applies to every formulation we develop, regardless of the sector, the scale or the customer.
Where formulation becomes certainty
Our in-house laboratory is the starting point for every product we manufacture. Formulations are developed, tested and validated here before anything goes near a production line. Stability testing, safety assessment, performance verification: all conducted internally by our chemistry team. You are not waiting for a third-party lab to sign off your brief. The expertise is in the building.
Ethical sourcing
Never tested on animals, always sourced with purpose. Every raw material that enters our facility is assessed against a clear set of ethical criteria. We do not work with ingredients tested on animals. We prioritise vegan-suitable formulations as a default position, not as an exception. Suppliers are evaluated through SEDEX audit for ethical employment, environmental management and responsible sourcing practices. From forestry-certified packaging to REACH-registered actives, every purchasing decision is made with the same question: is this the right choice, not just the available one.
Regulatory expertise
The Biocidal Products Regulation is one of the most complex and rapidly evolving legislative frameworks in the household and personal care sector. We have been working within it and preparing for its changes for years. Our chemistry team monitors BPR developments, tracks active substance review timelines and ensures that every biocidal product we manufacture is not only compliant with current requirements but ready for the next set. We also navigate UK REACH, EU REACH, CLP labelling requirements and relevant FDA and EPA standards for customers supplying the USA market. Compliance is not a checklist here. It is a discipline.
Fragrance
Fragrance is chemistry. Getting it right requires an understanding of how aromatic compounds behave in a formulation, how they interact with other actives, how they survive the manufacturing process and how they perform in the finished product over time. Our laboratory handles the stabilisation work that sits between a fragrance concept and a product that actually delivers on the shelf. We work with leading global fragrance houses, giving our customers access to the same scent development capability used by the world's largest brands. Whether you are building a signature scent for a new product or reformulating an existing range, the chemistry and the connections are already here.

Whether you need a formulation developed from scratch, a compliance review on an existing product or access to fragrance development partnerships, our team is ready to talk. We work with brands at every stage, from first concept to full production.
Questions
Find answers to common questions about our manufacturing process.
Every supplier we work with goes through a robust approval process before a single ingredient enters our facility. We assess against ethical sourcing criteria including SEDEX audit compliance, REACH registration, cruelty-free status and environmental management practices. Approved supplier status is not a one-time gate. It is an ongoing relationship with regular review. We source the right product at the right price, and those two things are never in conflict with each other.
From day one. New product development at Sachets does not start on the production floor. It starts in the lab, and it starts with the right questions. Can we make this product safely? What are the format-specific risks? What does the safety assessment tell us? Our HACCP team is involved at the very beginning, conducting product risk assessments and site risk assessments before any formulation work begins. The chemistry and the safety case are developed together, not sequentially.
HACCP stands for Hazard Analysis and Critical Control Points. It is the management framework we use to identify, assess and control the risks that matter most in the development and manufacture of every product. At Sachets, the HACCP management plan covers the full production journey: from raw material sourcing and supplier traceability through to batch manufacturing, in-process testing and final quality assurance. It is not a document that sits in a drawer. It is how we work.
Every product we manufacture carries full traceability from raw ingredient through to finished batch. We know where every material came from, which supplier provided it, which batch it belongs to and how it performed through every stage of the manufacturing process. That traceability is available for regulatory submission, retail buyer audit or customer assurance at any point. Our batch control and documentation systems are designed to make that information accessible quickly, because when a customer or regulator needs it, speed matters.
Critical control points are the specific stages in our development and manufacturing process where a failure would have the most significant impact on product safety, quality or compliance. Identifying them accurately is at the heart of good HACCP practice. For us, that means looking hard at sourcing decisions, formulation variables, processing conditions, filling and packaging parameters, and final product testing. Each critical control point has a defined limit, a monitoring method and a corrective action plan. Nothing is left to assumption.
