Private Label Biphasic Makeup Remover
Shake, soak, gone — the waterproof-makeup eraser.
Stability and shelf-life questions
Why two layers?
Oil dissolves waterproof films; water rinses without grease — shaking mixes them for the job, settling separates them for the shelf.
Safe for lash extensions?
Oil-based removers loosen extension glue — we flag usage guidance clearly to protect both lashes and reviews.
Contact lens wearers?
Yes with our ophthalmologist-tested base; the sting-free claim is tested, not assumed.
Build the routine around it
Private Label Micellar Water
The no-rinse workhorse — gentle micelles for gym bags, travel and lazy nights.
Private Label Cleansing Oil
The first-step cleanser that melts SPF and makeup — rinse-clean without the greasy film.
Private Label Mascara Manufacturing
Mascara is the highest-repeat-purchase color SKU — and the most formulation-sensitive. The product is a system: the waxy base, the film-former package, and above all the wand. Two identical bases with different wands behave like different products, which is why we treat wand selection as the core engineering decision.
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.
Biphasic remover is the only honest answer to waterproof mascara: oil and water phases that shake together, dissolve film formulas on contact and separate again in the bottle — the visible two layers are the product's own instruction manual.
We engineer phase-split speed (fast enough to look fresh, slow enough to work), keep the eye zone ophthalmologist-tested and contact-lens-safe, and verify zero oily smear on the skin after rinsing — the category's main complaint.
The stages this fluid passes through
- 1
Set the overage deliberately
The level is set so the product is still inside specification at the end of shelf life, rather than only at the moment it leaves the line.
- 2
Choose the pack
Airless, pump, dropper or tube — the format is selected for the viscosity and for the barrier it can provide.
- 3
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.
- 4
Clarify by filtration
Filtration is matched to the viscosity so the product stays clear without stripping out what gives it body.
The number that matters is the assay at the end of shelf life
A fluid can leave the factory at full strength and arrive at month twenty-four below it, because degradation is continuous and invisible until something changes colour. The specification is therefore written against the end of the shelf life, not the day of fill.
That is what sets the overage, and the overage is what sets the cost. A formula that loses a few per cent a year is managed differently from one that holds its level, and the difference shows up in the price per unit.
Which fluid route fits which active
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 |
|---|---|---|
| Buffer-controlled fluid | Standard pack, tight pH control | Actives that only work in a narrow pH window |
| Two-chamber or mix-at-use | Separated phases until activation | Actives that cannot hold a shelf life in solution |
| Preservative-light fluid | Airless or single-dose pack | Markets where the preservative profile is restricted |
| Concentrated serum gel | Airless pump to handle the viscosity | High-load actives sold on a small dose |
Why a fluid is checked against a sample, not a number
Assay and pH tell you whether the chemistry is right; they do not tell you whether the product looks the way the buyer approved. Colour and clarity are read against the retained Golden Sample.
Production runs on GMPC and ISO 22716 certified lines under manufacturing licence 粤妆20250206, traceable from raw material to carton on every batch.
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 |
|---|---|---|
| Isohexadecane | 15–30% | Waterproof film dissolution |
| Water + Humectant Phase | balance | Rinse-clean comfort |
| Panthenol | 0.5–1% | Lash-zone care |
| Chamomile Extract | 0.5–1% | Eye-zone calm |
What decides whether this stays stable
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.
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.
Trace metals at parts per million
Iron and copper catalyse oxidation far below the level any incoming specification would flag. A chelator is part of the design, not an optional additive.
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.
Formats and order quantities
Mixed-variant orders can split the stated MOQ across formats under one brand.
| Format / Specification | MOQ | Lead Time |
|---|---|---|
| Biphasic eye-lip remover 100 ml | 1,000 pcs | 10–15 days |
| Travel 50 ml with rounded cap | 1,000 pcs | 10–15 days |
| Remover duo (biphasic + micellar) | 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.
