The stages this fluid passes through
- 1
Verify dosage across the pack
Where the pack meters a dose, the delivered volume is checked across the life of the pack rather than only when it is full.
- 2
Dose the chelator against the water
The chelation level follows the incoming water and raw materials rather than a fixed line, because trace metals vary from source to source.
- 3
Flush the headspace
Where oxygen-sensitive actives are present, the headspace is displaced before the pack is sealed.
- 4
Choose the barrier pair
Oxygen and light barriers are selected together with the pack, since either one alone leaves an oxidation route open.
Astaxanthin is dosed at 0.1–0.5% — far below most actives — yet delivers documented antioxidant capacity that makes the marketing numbers sing. The microalgae origin story (Haematococcus pluvialis) gives clean-beauty shelves a science-backed hero ingredient.
The molecule tints formulations coral-orange, so we engineer either a warm glow aesthetic or mask it in richer emulsions depending on your positioning. Oil-phase solubilization is handled with cosmetic-grade carriers to keep the base clear and elegant.

Buyer guides for this build
Before you brief a supplier on this category, these are the guides that answer the questions buyers ask next — timelines, order quantities, cost structure and compliance.
Documentation that ships with the order
Every production order leaves with a certificate of analysis, a stability summary, a microbiology report and MoCRA / CPNP-ready documentation, produced on GMPC and ISO 22716 certified lines under licence 粤妆20250206.
Because a fluid gives its actives nowhere to hide, the retained Golden Sample is kept for clarity and colour, which is what a batch is checked against alongside the assay.
What decides whether this stays stable
Filtration has a pore size
Filtration fine enough to guarantee clarity can also strip a high-molecular-weight active or shift the viscosity. The pore size is chosen against both requirements at once.
The pH window is narrower than solubility
The range where an active is stable is often tighter than the range where it dissolves. Both ends are verified at fill rather than assumed.
Chelation is dosed, not added
Too little chelator leaves trace metals free to catalyse oxidation; too much can undercut the preservation system or shift the pH. The level is set against the water and the raw materials.
Water quality is an ingredient
Purified water has its own specification, and it matters more here than in any other format because it is most of the formula.
What this fluid is built around
INCI names and typical levels reflect publicly documented formulation practice. All values are adjustable in your build.
| Ingredient (INCI) | Typical Level | Function & Benefit |
|---|---|---|
| Haematococcus Pluvialis Extract (astaxanthin) | 0.1–0.5% | Carotenoid antioxidant hero |
| Squalane | 20–50% | Clear oil carrier |
| Ubiquinone (CoQ10) | 0.1–0.5% | Mitochondria-story pairing |
Formats, pack sizes and MOQ
Mixed-variant orders can split the stated MOQ across formats under one brand.
| Format / Specification | MOQ | Lead Time |
|---|---|---|
| 0.5% astaxanthin glow serum, 30 ml dropper | 1,000 pcs | 10–15 days |
| 0.1% + squalane day emulsion, 30 ml pump | 1,000 pcs | 10–15 days |
| Astaxanthin + CoQ10 night oil, 30 ml | 1,000 pcs | 10–15 days |
MOQ and lead time above are the standard liquid, cream and gel route. The real minimum is set by the manufacturing system rather than the category: surfactant systems (shampoo, body wash) start at 2,000 pcs, stick formats at 3,000, and powders and sheet masks at 5,000 — with longer production runs to match.
Stability and shelf-life questions
Why such a low concentration?
Astaxanthin is active at fractions of a percent — dosing higher adds cost and color without benefit. The low dose is chemistry, not corner-cutting.
Will it stain skin orange?
No — at 0.1–0.5% in a well-solubilized base it leaves a subtle warmth at most. We verify no-transfer during stability testing.
What is its shelf stability?
Carotenoids resist oxidation reasonably well; with amber packaging we document 24-month shelf life.
Preservation is a design decision, not an additive
A water-based product needs a preservation system chosen against its own pH, its own water activity and the way it will be used. Choosing one before the formula is fixed almost always means redoing the work later.
The study runs against the finished matrix, and for anything dispensed by hand it runs against the in-use pattern as well, because that is where contamination actually enters the product.
Which fluid route fits which active
The base is chosen around the least stable thing in the formula rather than around the headline ingredient.
| Route | Barrier it needs | Where it fits |
|---|---|---|
| Glycol-rich fluid | Modest barrier, higher water activity | Actives that need solubility more than protection |
| Biphasic | Two phases, shaken before use | Formats that need an activation step |
| Structured gel | Chelator with no oil phase to protect | Treatment and gel-adjacent formats |
| Two-chamber or mix-at-use | Separated phases until activation | Actives that cannot hold a shelf life in solution |
