2% BHA Liquid Exfoliant Toner
The single most reviewed exfoliant type in Western skincare — pH-controlled, pore-deep, leave-on.
MOQ from 1,000 pcs (stock formula) · GMPC + ISO 22716 · US FDA registered
Salicylic acid is the hero of the Western acne and blackhead category, and the leave-on 2% liquid exfoliant is its best-selling format: oil-soluble, pore-penetrating, and gentle enough for regular use when the pH is properly controlled. This is one of the most formula-sensitive SKUs in skincare — get the pH or the solvent system wrong and the product either does nothing or irritates — so it is a strong differentiator for factories that can document their process.
We manufacture 2% BHA leave-on toners with a pH window of 3.2–3.8, verified on every batch. The base uses a glycol solvent system that keeps salicylic acid fully dissolved (no crystallization on the bottle), with green tea and soothing agents to widen the tolerance envelope. Oilier-skin brands can pair it with our niacinamide serum as a complete pore-care routine.

|---|---|---|
| Salicylic Acid | 2% | Oil-soluble BHA; clears pore linings, reduces blackheads and blemishes |
| Methylpropanediol / Butylene Glycol | q.s. base | Solvent system that keeps salicylic acid dissolved and aids penetration |
| Camellia Sinensis (Green Tea) Extract | 1% optional | Antioxidant and soothing counterweight to the exfoliating action |
| Willow Bark Extract | 1% optional | Natural-source BHA-family extract for 'plant-derived' positioning |
| Sodium Hydroxide | q.s. to pH | pH adjustment into the documented efficacy window |
How We Engineer This Formula
pH Control Is the Product
Salicylic acid works in a narrow pH window — high enough to avoid unnecessary irritation, low enough to stay active. We verify pH 3.2–3.8 on every batch and can show the measurement records. This is the single most common failure point in cheap BHA products, and documenting yours is a genuine sales advantage.
Solvent system prevents crystallization
Salicylic acid is poorly water-soluble; poorly engineered formulas crystallize around the bottle neck within weeks. Our glycol-solvent base keeps the acid fully dissolved for the full shelf life — the liquid stays clear, and the stated 2% reaches the skin.
Routine ecosystem built in
BHA exfoliants drive repeat purchase of adjacent SKUs: cleansers, niacinamide serums, and moisturizers. We manufacture the full pore-care routine under one roof, which simplifies your supply chain and guarantees the products were formulated to work together.
Manufactured In-House, Documented Per Batch
pH measurement and assay verification on every BHA production batch.
Our factory (Guangdong Kuaiying Biotechnology, license 粤妆20250206) runs GMPC and ISO 22716-certified lines with batch traceability from raw material to carton. Every production order ships with certificate of analysis, stability summary, microbiology report and MoCRA/CPNP-ready documentation.

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.
Frequently Asked Questions
Is a 2% salicylic acid product a cosmetic or a drug?
In the EU and UK it is a cosmetic. In the US, acne-treatment claims push a product into the OTC drug monograph; cosmetic positioning uses appearance-based language ('reduces the look of blackheads'). We map the claim language for your target market and can support the OTC route for US acne positioning if you want to go that way.
What is the MOQ and can I get toner pads instead of a liquid bottle?
1,000 pcs per SKU on the stock liquid base; the pad-in-jar format uses the same 1,000 pcs floor even though it adds a component line. Both formats share the same verified 2% / pH 3.2–3.8 system.
How do you keep the product from crystallizing or separating?
Through the solvent system and pH control, verified by 3-month accelerated stability and freeze-thaw testing. BHA crystallization is a formula failure we specifically engineer out — your liquid stays clear for the full shelf life.
Can you build a complete acne-care routine for my brand?
Yes — a typical set is a gel cleanser, this 2% BHA liquid, a niacinamide 10% serum and an oil-free gel moisturizer. We formulate them as a system and quote the whole set in one PI.
