Small Batch Cosmetic Manufacturing from Guires CSL
Small batch cosmetic manufacturing for launches and market tests: low MOQ runs, GMP batches at ISO 22716 partner facilities, then tech transfer to your contract cosmetic manufacturer when you scale. Searching for private label cosmetics or white label skin care? We go further, with custom formulas you own, made in low MOQ skin care and personal care batches, so you get the flexibility of a low MOQ cosmetic manufacturer and a formula no one else sells. Every product starts with pilot manufacturing at the Guires R&D Innovation Centre: pilot batches made to the signed-off process and used for stability, clinical and market testing before scale-up.

Questions
Asked before we start.
What is your minimum order quantity (MOQ)?
Batch size is set to your requirement. Pilot and launch batches can be small, and we transfer the product to a contract manufacturer when volumes grow.
What is your minimum order quantity?
There is no factory-style MOQ. Micro-batches are sized to your requirement, which makes us a low MOQ option for first launches.
What batch sizes can you make?
Batch sizes are set to your requirement, from small runs for sampling and market tests to launch volumes. Tell us what you need and we plan the run around it.
Can you manufacture at full commercial scale?
We make pilot and micro batches in-house and transfer to trusted full-scale partners when you grow.
Can I move production to my own manufacturer?
Yes. The tech-transfer pack is written so any capable manufacturer can make the product.
