Private Label Green Tea Serum
The antioxidant your customers already believe in — standardized EGCG calm.
The active system and its working levels
INCI names and typical levels reflect publicly documented formulation practice. All values are adjustable in your build.
| Ingredient (INCI) | Typical Level | Function & Benefit |
|---|---|---|
| Camellia Sinensis Leaf Extract | 50–80% | EGCG antioxidant base |
| Epigallocatechin Gallate (EGCG) | 0.5–1% | Standardized active fraction |
| Zinc PCA | 0.5–1% | Oil-balancing calm |
| Caffeine | 0.1–0.5% | De-puffing support |

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.
Green tea serum wins on pre-installed trust: customers arrive believing in the leaf, and the formulator's job is delivering enough standardized EGCG to justify the belief. Watery gel textures suit the oily-skin audience that gravitates to this SKU.
We use caffeine-and-EGCG-standardized camellia extracts so antioxidant claims survive supplier lot variation, and pair with zinc PCA for the oily-skin calm the category promises. Color stays a natural pale jade — no dyes.
What holds this fluid together over its shelf life
Headspace grows as it is used
A fluid loses volume and gains headspace with every use. The pack and closure are selected with that change in mind.
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.
Preservation in a water-rich base
High water activity calls for a preservation study against the finished matrix, not a calculation from the raw material list.
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.
What is adjustable on this fluid
- EGCG-standardized COA documentation
- Watery gel vs. light emulsion textures
- Vegan and cruelty-free positioning
- Oily-skin regimen bundle with clay mask
pH, stability and shelf-life questions
How is this different from your caffeine eye serum?
Different zone and dose — the eye serum targets morning puffiness; this one is a full-face antioxidant for shine-prone skin.
Does green tea oxidize in bottle?
EGCG is fragile, so we stabilize with chelators and amber glass; the stability data ships with your documentation.
Can we add fragrance?
Possible, but the category's audience skews sensitive-skin — we recommend fragrance-free for the first run.
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
Two fluids can look identical in the bottle and behave completely differently by the end of the shelf life.
| Route | Barrier it needs | Where it fits |
|---|---|---|
| Preservative-light fluid | Airless or single-dose pack | Markets where the preservative profile is restricted |
| Micellar system | Surfactant-stabilised, clear pack | Cleansing waters and no-rinse formats |
| Glycol-rich fluid | Modest barrier, higher water activity | Actives that need solubility more than protection |
| Low-water fluid | Airless or aluminium-barrier pack | Actives sensitive to oxygen and light |
Formats and order quantities
Mixed-variant orders can split the stated MOQ across formats under one brand.
| Format / Specification | MOQ | Lead Time |
|---|---|---|
| Green tea extract 80% watery serum, 30 ml | 1,000 pcs | 10–15 days |
| Green tea + zinc PCA oily-skin build, 30 ml | 1,000 pcs | 10–15 days |
| Green tea set (serum + clay mask) | 1,000 sets | 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.
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.
How a fluid goes from brief to released batch
- 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
Verify the water first
Purified water is checked against its own specification before anything is added, because it is the majority of the formula.
- 3
Build the protection
Chelation, oxygen barrier and light barrier are decided together, because any one alone leaves the product exposed.
- 4
Flush the headspace
Where oxygen-sensitive actives are present, the headspace is displaced before the pack is sealed.
