Featured Ingredients
Brightening
Tranexamic Acid
CAS 1197-18-8
Upstream PIH signal blocker. Targets the plasminogen pathway that converts skin inflammation into melanocyte stimulation.
Barrier Repair
Ceramide NP
CAS 24696-26-2
Primary skin lipid for lamellar structure restoration. Rebuilds the intercellular lipid matrix in compromised and sensitive skin.
Antioxidant
Ferulic Acid
CAS 1135-24-6
Sacrificial antioxidant and Vitamin C stabiliser. Doubles the photoprotective efficacy of the VC + VE combination stack.
Brightening
3-O-Ethyl Ascorbic Acid
CAS 86404-04-8
Stable Vitamin C derivative with dual water-and-oil solubility. pH 4.5–6.5 working range — no yellowing, no strict pH constraints.
Barrier Repair
Ectoine
CAS 96702-03-3
Natural extremolyte with cellular membrane stabilisation. Supports microbiome integrity and reduces inflammatory signalling — no known incompatibilities.
Antioxidant
Ergothioneine
CAS 497-30-3 · EGT
Super antioxidant with dedicated OCTN1 cellular transporter. Outperforms glutathione on hydroxyl radical quenching — fastest-growing premium active 2024–26.
PIH Signal Blocker
Tranexamic Acid
CAS 1197-18-8
Upstream PIH interception via plasminogen inhibition. Works where tyrosinase inhibitors alone fall short — inflammation-driven pigmentation.
Tyrosinase Inhibitor
Alpha-Arbutin
CAS 84380-01-8
Selective tyrosinase inhibition without the safety profile of hydroquinone. Effective across both UV-induced and PIH pigmentation.
Stable Vitamin C
3-O-Ethyl Ascorbic Acid
CAS 86404-04-8
Dual-soluble VC derivative stable at pH 4.5–6.5. Direct activity without the yellowing and pH constraints of L-Ascorbic Acid.
Transfer Inhibitor
Niacinamide
CAS 98-92-0
Blocks melanosome transfer from melanocyte to keratinocyte. Multi-functional: brightening + barrier support + sebum regulation.
Barrier Lipid
Ceramide NP
CAS 24696-26-2
Primary skin lipid for lamellar structure repair. Restores the intercellular lipid matrix that maintains barrier integrity.
Emollient
Squalane
CAS 111-01-3
Sebum-identical emollient that integrates into the lipid matrix. Oxidatively stable, non-comedogenic, suitable for all skin types.
Humectant
Sodium Hyaluronate
CAS 9067-32-7 · LMW & HMW
Available in LMW (0.1–0.15 MDa) and HMW (1.5–1.8 MDa) grades for targeted hydration at different skin depths.
Extremolyte
Ectoine
CAS 96702-03-3
Cellular membrane stabilisation and microbiome support. pH 4–8, stable to 120°C — no known incompatibilities with any cosmetic active.
VC Stabiliser
Ferulic Acid
CAS 1135-24-6
Sacrificial antioxidant that doubles the photoprotective efficacy of VC + VE. The essential third component of the antioxidant regeneration cycle.
Super Antioxidant

Ascorbyl Palmitate
CAS 137-66-6 · E304
The only Vitamin C form active in oil-phase and anhydrous systems. Protects lipid components from oxidative rancidity — food-grade (E304).
Mild Anionic Surfactant
SCI 85%
CAS 6789-32-0 · Sodium Cocoyl Isethionate
Primary surfactant for solid syndet bars. Skin-compatible pH 5.5–6.5, rich lather, hard water resistant — the standard for mild cleansing formats.
Mild Anionic Surfactant
Sodium Methyl Lauroyl Taurate
CAS 4337-75-1
Ultra-mild taurate surfactant for sensitive skin cleansers and baby care. Excellent foam quality with minimal barrier disruption.
Cationic Conditioning Emulsifier
BTMS-50
CAS 81646-13-1 · 50% Active
Self-emulsifying cationic system for hair conditioners. Deposits on damaged hair through electrostatic attraction — survives rinsing.

Formulation-Grade Guidance.
Most ingredient suppliers provide a spec table. We provide mechanism data, formulation parameters, pH windows, phase behaviour, and known incompatibilities — on every product page, free, no account required. Because a datasheet alone does not help you build a product.
- Mechanism of action documented on every product page
- Formulation parameters: dosage, pH range, addition temperature, phase behaviour
- Ingredient compatibility guidance — synergies and known conflicts
- 53 technical articles and sourcing guides in our Knowledge Hub
- Technical enquiries answered by people who understand the chemistry

Meet the Founder
Lulu Chen
Founder · Onerchem · Wuhan, China
"Every enquiry is handled by someone who understands the chemistry — not a sales team with a quota. If you have a formulation question, ask it. That is why we built the Knowledge Hub, and it is why I answer technical questions personally."
Onerchem was founded in 2022 on a specific observation: international formulators were well-served on price, but poorly served on technical depth. Most suppliers provided datasheets. Very few provided the formulation-grade knowledge that lets a chemist make a confident decision quickly.
We built Onerchem to close that gap — a B2B ingredient supplier that takes the technical side as seriously as the commercial side. That means HPLC-verified purity on every active, batch-specific documentation on every order, and a supplier who responds to technical questions with actual answers.
