Private Label Co-Wash
The wash that conditions while it cleanses — no lather anxiety allowed.
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 wash the file pairs that traceability with the retained Golden Sample, which is what a batch is compared against at release when the lather or the viscosity has to be judged rather than only recorded.
Other cleansing and care builds

The middle path — enough lather to feel clean, mild enough to graduate from co-wash.
Private Label Curly Hair Shampoo
Curls have rules — this wash follows all of them.

Definition by curl pattern — creams and gels tuned from loose waves to tight coils.
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 label percentage tells you almost nothing about a wash
In a rinse-off product the active has seconds of contact and unlimited dilution working against it. Dosing for what remains after that is a different calculation from dosing a leave-on, and it is the calculation that decides whether a claim is worth printing.
The rest is texture and rheology. How the base thickens in the hand, how the foam builds, and whether hair or skin feels stripped or cushioned afterwards — all of it comes from the surfactant blend, not from the headline ingredient.
The cleansing systems we can fill today
Every system below is production-ready today. Which one we build is decided by the claim and the price tier, not the other way round.
| System | Lather character | Where it fits |
|---|---|---|
| Sulfate systems | High volume, instant foam | Value and clarifying tiers with no sulfate-free claim |
| Isethionate blend | Dense and cushioned, close to conventional | Brands that cannot accept a lather downgrade |
| Glucoside and glycinate | Creamy and dense at the same time | Premium facial cleansers and body washes |
| Sarcosinate blend | Fast-building with a clean rinse-off | Daily-wash lines where residual feel matters |
Questions buyers ask before a first run
Does co-wash actually clean the scalp?
At our amphoteric doses, yes — the failure mode of bad co-washes is buildup, which is why we publish the three-week verification.
Tub or bottle?
Tub — the tradition is scooping with fingers; the wide opening is part of the ritual's ergonomics.
Straight hair allowed?
The community will joke, the dry-hair mainstream will buy — position honestly to both.
Co-wash replaces shampoo with a cleansing conditioner: surfactants mild enough for daily use, conditioners rich enough to define curls. The curly community made it a ritual; the dry-hair mainstream is following.
We balance genuinely cleansing amphoteric doses with rich cationic conditioning, verify scalp-clean without buildup across three weeks of use (the co-wash failure mode), and design the tub packaging the format tradition expects.
The parts of the brief that matter most
Hard water changes the foam
Calcium and magnesium in the supply collapse lather and can leave insoluble residue. Chelation is specified against the hardness of the destination market.
Where the activity actually happens
Contact time is measured in seconds and the rinse dilutes everything. We dose for what remains on the surface instead of for the number printed on the front of the pack.
A mildness claim needs a method
Protein-denaturation and zein testing give a comparable number across systems, and one of them is usually what a mildness claim rests on. The test is run against your finished blend rather than the raw material's published figure.
Fill viscosity is not shelf viscosity
A base that pumps cleanly on the line can be noticeably thicker in the bottle a month later. Both ends of the curve belong in the specification.

How we take a wash from brief to released batch
- 1
Adjust viscosity at fill temperature
Thickening is adjusted at the temperature the product will actually be filled at, not at the temperature it was made at.
- 2
Lock the pH window
pH is specified with a tolerance and verified at fill, because it moves the foam, the viscosity and the comfort of the finished wash together.
- 3
Verify against the approved sample
Every batch is compared with the retained Golden Sample before release, so the bottle your customer opens matches what you signed off.
- 4
Check clarity at the cold end
The batch is cooled to the coldest shelf the product will see and checked for haze, which is where a marginally soluble component shows up first.
Pack formats, MOQ and lead time
Mixed-variant orders can split the stated MOQ across formats under one brand.
| Format / Specification | MOQ | Lead Time |
|---|---|---|
| Co-wash tub 350 ml | 1,000 pcs | 10–15 days |
| Co-wash + scalp-brush kit | 1,000 sets | 10–15 days |
| CG complete kit (co-wash + low-poo + cream) | 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.
The cleansing system behind the claim
INCI names and typical levels reflect publicly documented formulation practice. All values are adjustable in your build.
| Ingredient (INCI) | Typical Level | Function & Benefit |
|---|---|---|
| Coco-Betaine | 5–10% | Gentle cleansing base |
| Behentrimonium Methosulfate | 1–3% | CG-safe conditioning |
| Cetearyl Alcohol | 3–6% | Creamy structure |
| Shea Butter | 2–5% | Curl nourishment |
