DDAC (Didecyldimethylammonium Chloride) Supplier Malaysia
- Also known as
- Didecyldimethylammonium Chloride
- Didecyl Dimethyl Ammonium Chloride
DDAC supplier in Malaysia for industrial buyers specifying didecyldimethylammonium chloride as a biocide or disinfectant raw material. Also called didecyl dimethyl ammonium chloride, DDAC is a single-active quaternary ammonium compound offered as aqueous solutions for formulation work.
Commercial coverage includes concentrated DDAC solutions such as typical 40% and 80% active grades used in hard-surface disinfectant bases, sanitiser systems, cooling-water biocides, wood-preservation mixes and algaecide formulations. Strength, colour and other acceptance limits should be stated in the enquiry so the quotation can match the required solution grade.
Formulators in cleaning, water treatment and related manufacturing select DDAC when a didecyl-based quaternary active is required. It is not the same product as benzalkonium chloride (BKC, BAC or ADBAC) or DADMAC, so those materials should be requested on their own product pages when needed.
Send the required DDAC solution strength or grade, application, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation.

DDAC 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 |
|---|---|---|---|---|
| DDAC 40% aqueous solution | clear to pale yellow aqueous liquid | typically about 40% active matter; confirm against the required grade | Disinfectant raw-material bases, sanitiser and cleaner formulations, and industrial biocide blends where a mid-strength DDAC solution is specified. | Confirm the required pack format with the quotation. |
| DDAC 80% concentrated solution | clear to pale yellow concentrated liquid | typically about 80% active matter; confirm against the required grade | Concentrated formulation work for hard-surface disinfectant bases, cooling-water biocides, wood-preservation mixes and related industrial systems that dose from a high-active DDAC solution. | Confirm the required pack format with the quotation. |
| Water-treatment biocide grade DDAC | aqueous solution at the requested strength | — | Industrial water-treatment and cooling-water biocide formulations where didecyldimethylammonium chloride is the specified quaternary active. | Confirm the required pack format with the quotation. |

Common questions about DDAC
What is DDAC?
DDAC is didecyldimethylammonium chloride, also written didecyl dimethyl ammonium chloride. It is a single-active quaternary ammonium compound supplied as aqueous solutions for industrial formulation. State the required active strength when enquiring.
Is DDAC the same as benzalkonium chloride or BKC?
No. DDAC is didecyldimethylammonium chloride. Benzalkonium chloride, also called BKC, BAC or ADBAC, is a different quaternary ammonium identity and should be requested separately. Generic QAC language and DADMAC are also not interchangeable with DDAC.
Which DDAC solution grade should I request?
Commercial buyers commonly specify aqueous solutions around 40% or 80% active matter, or a water-treatment biocide grade at a stated strength. Provide the required assay, appearance limits and end use so the quotation can match the correct solution.
What applications use DDAC as a raw material?
DDAC is used in hard-surface disinfectant bases, sanitiser and cleaner formulations, industrial water-treatment and cooling-water biocides, wood-preservation mixes and related manufacturing blends. Suitability depends on the complete formulation and the buyer's specification.
Can packing and documentation be requested with the quotation?
Yes. List the preferred pack format and any product documents required with the enquiry. Available packing, documentation and commercial details are confirmed for the quoted grade.
What details are needed for a DDAC price enquiry?
Provide the solution strength or grade, application, target specification, quantity and delivery location. Mention preferred packing, documentation needs and timing so the quotation can cover the full requirement.
