Private Label Self-Tan Drops
Tanning that adapts to your customer's routine — drops, mixed in.
Self-tan drops re-invented the format: a DHA concentrate mixed into whatever moisturizer the customer already loves, with dose-controlled results — two drops for subtle, eight for serious. The format's genius is it asks the customer to change nothing.
We build stable DHA concentrates with the dropper precision the dose-control story requires, verify mix-ability across common lotion bases, and position face-safe claims with the eye-area wording handled properly — the compliance details done upfront.
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 |
|---|---|---|
| Micellar system | Surfactant-stabilised, clear pack | Cleansing waters and no-rinse formats |
| Alcohol-based tonic | Simple pack, evaporating base | Oil-control formats and fast-dry tonics |
| Concentrated serum gel | Airless pump to handle the viscosity | High-load actives sold on a small dose |
| Emulsion-fluid hybrid | A light oil phase suspended in water | Slip and comfort without the weight of a cream |
Traceability from raw material to carton
Each batch is traceable from the incoming raw material through to the sealed carton, on GMPC and ISO 22716 certified lines operating under licence 粤妆20250206.
For a fluid the traceability record is read with the retained Golden Sample and the stability data, because colour, clarity and assay each move on their own timeline.
The stages this fluid passes through
- 1
Flush the headspace
Where oxygen-sensitive actives are present, the headspace is displaced before the pack is sealed.
- 2
Hold for microbiological release
For a fluid the microbiological result is often the last gate before filling, and the batch waits for it.
- 3
Fix the active system
Routes and levels are set against the claim, then checked for compatibility with each other before the base is built.
- 4
Clarify by filtration
Filtration is matched to the viscosity so the product stays clear without stripping out what gives it body.
The functional system in this base
INCI names and typical levels reflect publicly documented formulation practice. All values are adjustable in your build.
| Ingredient (INCI) | Typical Level | Function & Benefit |
|---|---|---|
| Dihydroxyacetone (DHA) | 8–12% | Concentrate potency |
| Erythrulose | 1–2% | Even-development support |
| Glycerin | 3–8% | Mix-base compatibility |
Where a fluid build succeeds or fails
Headspace oxygen
Air left in the bottle keeps reacting after fill. Low-oxygen filling removes most of the oxygen the product will ever encounter.
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.
Viscosity keeps building after fill
Polymer-thickened fluids can continue to develop structure for days after filling. Specification limits are written for the settled product, not for the freshly made one.
Colour shift is the early warning
Long before an assay moves, a sensitive active usually shows a colour change. It is checked against the retained sample at release.

pH, stability and shelf-life questions
How does mix-in work?
DHA reacts with skin protein regardless of carrier — drops mixed into moisturizer tan exactly where applied, at the dose the customer chose. Dose control is the format's whole promise.
Face-safe?
The concentrate formula is face-compatible; we supply the eye-area and sensitivity wording per market so claims stay clean.
Why dropper packaging matters?
Dose control IS the product — a dropper that doses inconsistently breaks the core promise. Dropper QC is a release gate.
Formats, pack sizes and MOQ
Mixed-variant orders can split the stated MOQ across formats under one brand.
| Format / Specification | MOQ | Lead Time |
|---|---|---|
| Self-tan drops 30 ml dropper | 1,000 pcs | 10–15 days |
| Face-specific light variant | 1,000 pcs | 10–15 days |
| Tan trio set | 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.
Start with the pH window
If your active has a narrow one, say so first — it decides more of the formula than any other single input. We reply with the matching base within 24 hours.
