Sugar Chemicals

What sugar mill chemicals are

Dyna Glycols lists carbamate biocides plus descaling and decolouring process aids for sugar mills. Named carbamates are sodium dimethyl dithiocarbamate (SDMDC) 40%, potassium dimethyl dithiocarbamate (KDMDC) 40% and nabam (ethylene bis-dithiocarbamate) 40%. They are mill-water and process biocides, not food additives and not a sugar-quality claim.

Descaling and decolouring agents are supplied against the duty named on the enquiry. Do not assume a generic acid descaler or a colour adsorbent from this page without that specification. Food-contact or additive status is not implied.

How Dyna Glycols manufactures sugar mill chemicals

Carbamate solutions are finished to the 40% active window listed. QA follows active content, pH and appearance. Custom actives are quoted after mill volume.

Descaling and decolouring companions are sampled when the mill describes scale type (carbonate, oxalate, sucrose char) or the colour body. They are not a secret catalogue of unnamed acids.

Typical grades in this range

Name biocide vs descaling vs decolouring. Listed carbamates are below.

• SDMDC 40%: sodium dimethyl dithiocarbamate
• KDMDC 40%: potassium dimethyl dithiocarbamate
• Nabam 40%: ethylene bis-dithiocarbamate
• Descaling agents (specify scale type and metallurgy)
• Decolouring agents (specify juice or liquor and the colour test)

Where sugar mill chemicals are used

Sugar mill cooling water, imbibition and selected process streams use dithiocarbamates as microbiological control where the mill still permits that chemistry. Sodium vs potassium vs nabam is a mill specification, not a warehouse substitution.

Evaporator and pan scale uses a descaling path matched to the deposit and the stainless or brass metallurgy. Liquor colour uses a decolouring aid matched to the mill test (ICUMSA or other). Those duties are not carbamate biocides.

How to specify sugar mill chemicals

Send sodium vs potassium vs nabam, % active, mill stream, contact time and any residual or effluent limit. For descaling, send deposit analysis and metallurgy. For decolouring, send the colour method and whether the stream is juice, syrup or liquor.

Confirm the mill still allows dithiocarbamate chemistry. Several food-chain briefs have moved away from it. Dyna Glycols will not claim a food-additive function for these biocides.

Quality, documents and supply

Carbamate lots are released against active content, pH and appearance. SDS and COA follow verification. Biocidal performance is a mill test in the actual water.

Protect solutions from frost. Follow the SDS for handling, PPE and transport class. Keep away from acids that can release hazardous gases — read the SDS first.

Practical notes on sugar mill chemicals

Related carbamate listings also appear under agro and paper as industrial biocides. The sugar mill brief still belongs on this enquiry so dose and documentation match.

Do not mix carbamate biocides with oxidising biocides without mill chemistry approval.

Descaling over-acidification attacks metal. The mill metallurgist should approve the acid type. Dyna Glycols samples against the named duty, not a universal mill cleaner.

English is the source language for active-content claims. Machine translation is not a specification.

Freeze 40% active and the cation (Na vs K) once a trial is approved.

Request SDS with the first sample. Carbamates are classified materials in many transport regimes.

Ordering and evaluating sugar mill chemicals

Send the application, the analytical window and the pack size when you request a laboratory sample of sugar mill chemicals. SDS, TDS and COA follow a short company check. Handle and store the grade as the SDS describes.
