Sodium Dodecylbenzene Sulphonate (LAS) Supplier in Malaysia
- Also known as
- LAS
- SDBS
- Sodium Dodecylbenzene Sulfonate
- Sodium Alkylbenzene Sulphonate
Sodium dodecylbenzene sulphonate is the sodium salt of linear alkylbenzene sulphonic acid, supplied to detergent and cleaner manufacturers in Malaysia as a dried high-active powder. It is the neutralised salt, not the un-neutralised acid sold as LABSA. The trade also calls it LAS, SDBS, sodium alkylbenzene sulphonate and, in the American spelling, sodium dodecylbenzene sulfonate.
Dried grades are ordered on nominal active matter, commonly 80% and 90%, as a white to cream powder or as needles. Lower-active aqueous slurry and paste grades are also on the market for water-based lines. Commercial material is based on a predominantly straight-chain C10 to C13 alkylbenzene.
Beyond active matter, the figures a formulator states are free oil or unsulphonated matter, sodium sulphate content, moisture and colour. Send those limits with the enquiry so the quoted grade is matched to the formulation rather than to a published average.
It is the highest-volume anionic surfactant in detergent manufacture, used in laundry powder, detergent bars, dishwash, hard-surface cleaners, toilet blocks and industrial detergents, with further duty in textile auxiliaries and as an emulsifier. Send the required active matter, form, quantity and delivery location with your enquiry. Availability, packing and documentation are confirmed with the quotation.
- Grade
- 80% active powder, 90% active powder, slurry
- Appearance
- white to cream powder or needles; slurry grades are a pale viscous liquid
Sodium Dodecylbenzene Sulphonate 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 |
|---|---|---|---|---|
| LAS 90 dried powder | white to cream free-flowing powder | nominal 90% active matter; confirm against the quoted specification | High-active dry surfactant for laundry powder and detergent bar manufacture, where water is charged separately and dosing is by active matter. | confirmed with the quotation |
| LAS 80 dried powder or needles | white to cream powder or needles | nominal 80% active matter; confirm against the quoted specification | Dry blending into laundry powders, industrial and institutional detergents and cleaning powders. Needles raise less dust than a fine powder when bags are charged by hand. | confirmed with the quotation |
| Sodium alkylbenzene sulphonate slurry | pale viscous aqueous slurry or paste | lower active matter than the dried grades; state the required figure | Liquid dishwash, hard-surface cleaners and other water-based lines that would rather dose a slurry than dissolve a solid. | confirmed with the quotation |

Sodium Dodecylbenzene Sulphonate applications
Safety and handling
Store sealed in a cool, dry place and keep the dried grades away from moisture, because a high-active powder picks up water and cakes. Handle the powder with dust control and follow the handling instructions supplied for the quoted grade. Supply is subject to applicable requirements.
Common questions about sodium dodecylbenzene sulphonate
Is sodium dodecylbenzene sulphonate the neutralised form of LABSA?
Yes in chemistry, but they are separate purchases. This page covers the neutralised sodium salt, usually a dried high-active powder. Linear alkylbenzene sulphonic acid, or LABSA, is the un-neutralised viscous acid and has its own page, so order the acid by name if that is what your process needs.
What does LAS 80 or LAS 90 mean?
Those are commercial shorthand for nominal active matter, 80% and 90% respectively, in the dried grades. Confirm the active figure and any limits for free oil, sodium sulphate, moisture and colour against the quoted specification rather than treating the number as a full spec.
Should I order powder, needles or slurry?
Dried powder and needles suit dry blending into laundry powders and detergent bars, and needles are easier on an operator charging bags by hand. Slurry suits water-based lines that dose a liquid. Tell us how the surfactant is charged and the form follows from that.
Which specification limits matter to a detergent formulator?
Active matter is the first figure, then free oil or unsulphonated matter, sodium sulphate content, moisture and colour. Send the limits your formulation works to and the quoted grade is matched against them.
Is SDBS the same material as sodium alkylbenzene sulphonate?
Yes, the same material. Sodium dodecylbenzene sulphonate, SDBS, sodium alkylbenzene sulphonate and LAS all name the neutralised sodium salt of linear alkylbenzene sulphonic acid, written either sulphonate or sulfonate.
What packing and documents come with a quotation?
Send the required quantity and any packing or documentation requirements with the enquiry. Availability, packing and applicable documents are confirmed for the quoted grade rather than fixed on this page.
