Hydroquinone Supplier in Malaysia | Industrial Grade
- Also known as
- HQ
- Quinol
- 1,4-Dihydroxybenzene
- Benzene-1,4-Diol
Hydroquinone supplier for industrial buyers in Malaysia needing bulk raw material rather than consumer products. Also called HQ, quinol, 1,4-dihydroxybenzene and benzene-1,4-diol, this crystalline solid is selected as a polymerisation inhibitor, antioxidant intermediate and photographic chemical.
Commercial forms include technical industrial crystals or free-flowing powder, photographic grade and high-purity material. Powder is often preferred for charging and blending, while crystals or needles remain common for bulk industrial duty where free-flow characteristics are less critical.
Plastics and monomer plants use hydroquinone to stabilise acrylic acid, acrylates, styrene and vinyl acetate during storage. Rubber, unsaturated polyester, adhesive and photographic formulators specify it where inhibitor or developer chemistry is required.
Send the required grade or form, industrial application, target specification, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation.

Hydroquinone grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Technical industrial grade hydroquinone | crystalline solid, needles or free-flowing powder | — | Polymerisation inhibition and bulk industrial antioxidant duty where a technical grade is specified for monomer stabilisation or intermediate use. | Confirm the required pack format with the quotation. |
| Hydroquinone powder | free-flowing powder | — | Charging and blending where free-flowing powder is preferred over coarse crystals for inhibitor, antioxidant or intermediate preparation. | Confirm the required pack format with the quotation. |
| Photographic grade hydroquinone | crystals or powder to photographic specification | — | Photographic developing and related technical formulations that call for a photographic-grade hydroquinone rather than a general industrial grade. | Confirm the required pack format with the quotation. |
| High-purity hydroquinone | crystals or powder to high-purity specification | — | Intermediate synthesis and applications that require tighter purity controls than a standard technical grade. | Confirm the required pack format with the quotation. |

Hydroquinone applications
Safety and handling
Keep sealed in a cool, dry place and protect from air and light. Hydroquinone may darken on exposure; control dust during powder handling and follow the safety information for the quoted grade. Supply is subject to applicable requirements.
Common questions about hydroquinone
Is bulk hydroquinone the same as TBHQ or BHT?
No. Hydroquinone is benzene-1,4-diol, used as an industrial polymerisation inhibitor, antioxidant intermediate and photographic chemical. TBHQ is tertiary butylhydroquinone and BHT is butylated hydroxytoluene; each is a different substance with its own grade and application profile.
Which hydroquinone form or grade should I request?
Technical industrial crystals or powder suit monomer inhibition and general industrial antioxidant duty. Free-flowing powder is preferred for blending, photographic grade for developer formulations, and high-purity material where tighter controls are specified. State the application with the enquiry.
What industrial applications use hydroquinone powder or crystals?
Buyers typically use hydroquinone to inhibit polymerisation in acrylic and vinyl monomers, to stabilise unsaturated polyester and adhesive systems, as a rubber antioxidant intermediate, and in photographic developing chemistry. Describe the process so the suitable grade can be matched.
Do you supply hydroquinone for cosmetic or skin-lightening use?
This page covers industrial hydroquinone as a bulk raw material for polymerisation inhibition, antioxidants, intermediates and photographic use. Cosmetic, dermatological or consumer skin-care requirements are outside the intended supply scope described here.
What specifications should a buyer provide for hydroquinone?
State the intended industrial application and any required limits for assay, moisture, colour, melting range or impurity profile. For an existing process, include the current specification or a representative sample requirement so the quoted grade can be matched more closely.
What details are needed for a hydroquinone price enquiry?
Provide the grade or form, industrial application, target specification, quantity and delivery location. Mention preferred packing and any documentation needs so the quotation can address the complete requirement.
