Private Label Keratin Smoothing Treatment
Salon smoothing, at home — formaldehyde-free keratin systems activated by the flat iron.
Viscosity without weight is the whole craft of a fluid
A serum should feel like water and behave like a gel, and that combination is built with polymer choice and dosage rather than with more thickener. The two properties pull in opposite directions.
Push it one way and the product drips off the dropper; push it the other and it leaves a film on the skin. The sensory outcome of a fluid is decided in the rheology long before it is described on the pack.
Fluid bases and what each one can carry
The more the active needs protecting, the more of the decision moves from the formula to the pack.
| Route | Barrier it needs | Where it fits |
|---|---|---|
| Concentrated serum gel | Airless pump to handle the viscosity | High-load actives sold on a small dose |
| Micellar system | Surfactant-stabilised, clear pack | Cleansing waters and no-rinse formats |
| Simple aqueous | Chelator plus an opaque or UV-filtered pack | Stable actives in high-volume lines |
| Alcohol-based tonic | Simple pack, evaporating base | Oil-control formats and fast-dry tonics |
Keratin smoothing treatments deliver weeks of frizz reduction by depositing keratin films that the flat iron locks into the fiber. The compliance line is critical: formaldehyde and formaldehyde-releasers are restricted or banned in major markets, so modern systems are formaldehyde-free by design — and the claim is a selling point.
The at-home kit format (treatment + clarifying shampoo + aftercare conditioner) brought a salon service to retail, and the aftercare matters as much as the treatment: sulfate-free washing preserves the smoothing for its full claim window.
Build the routine around it
Private Label Sulfate-Free Shampoo
Gentle surfactant chemistry with the lather customers still expect — the premium-cleansing default.

The weekly intensive that photographs as luxury — rich treatments with measurable results.
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.
The actives and the levels they work at
INCI names and typical levels reflect publicly documented formulation practice. All values are adjustable in your build.
| Ingredient (INCI) | Typical Level | Function & Benefit |
|---|---|---|
| Hydrolyzed Keratin | 3–8% | Fiber-film smoothing agent |
| Glyoxylic-acid-class systems | compliant system | Formaldehyde-free smoothing |
| Cetearyl Alcohol + Cationics | base system | Deposit and glide |
What gets decided before the preservative system
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.
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.
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.
Compatibility between actives
Two actives that work alone can destabilise each other in the same bottle. Combinations are tested rather than assumed.
Where the compliance file comes from
The line is GMPC and ISO 22716 certified, and each batch carries raw-material-to-carton traceability under licence 粤妆20250206.
For a fluid the file is built on the preservation and stability studies run against the finished matrix, with the certificate of analysis, stability summary, microbiology report and MoCRA / CPNP-ready documentation attached to the order. Colour and clarity are read against the retained Golden Sample at release.

pH, stability and shelf-life questions
Is keratin treatment safe without formaldehyde?
Formaldehyde-free glyoxylic-class systems deliver smoothing without the restricted chemistry; documentation of the free-formaldehyde status is part of every dossier.
How long does smoothing last?
Typically 4–8 weeks depending on wash frequency — the aftercare pair exists precisely to protect that window.
Why does the kit include aftercare?
Sulfate shampoos strip the keratin films fast; the sulfate-free pair is what makes the longevity claim true, and it doubles the kit's ticket.
Order quantities by pack size
Mixed-variant orders can split the stated MOQ across formats under one brand.
| Format / Specification | MOQ | Lead Time |
|---|---|---|
| At-home smoothing kit (3-piece) | 1,000 sets | 10–15 days |
| Express smoothing treatment 150 ml | 1,000 pcs | 10–15 days |
| Salon-pro keratin system 1 L | 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.
The route an aqueous base takes through production
- 1
Verify against the retained sample
Assay, pH and appearance are checked at release against the sample your buyer approved.
- 2
Adjust and hold the pH
pH is set with the buffer system and then held, rather than corrected repeatedly at the end of the batch.
- 3
Screen solubility at the cold end
The batch is cooled to the coldest shelf it will meet and checked for haze, which is where an overloaded solubiliser system shows itself.
- 4
Build the buffer for capacity
The buffer system is chosen for how much acid or base it can absorb, not only for the pH it sets, so the window holds through storage.
