Application notes, material explainers and process guidance written around the chemicals we manufacture and export.
Can you eat triethylene glycol? The honest answer
No. Low acute toxicity is not a food clearance. What the question really asks, and why glycol purity testing is a life-safety…
Triethylene glycol in food-contact materials
Where TEG enters packaging and processing materials, who owns the compliance question, and which purity lines a converter should insist on.
Coating solvents and the substrate they are painted onto
A solvent chosen for the resin still has to meet the surface underneath. Where a glycol ether helps, and where it attacks.
Why adipic acid was once called a fat acid
The name is a fossil of an old manufacturing route. What it tells a buyer about grades, oxidation chemistry and the nitrous…
Glycol ethers by duty: matching the homologue to the job
Five industrial duties outside coatings, and how the methyl, ethyl and dipropylene members of the P-series divide the work between them.
Glycol coolant: seasonal buying and fluid management
A heat-transfer charge is a maintained asset, not a consumable. How to specify, test and buy ethylene glycol across a full seasonal…
Changing solvent supplier: the regulatory workload
Swapping the source of a solvent in a consumer product is a documentation project first. What regulatory affairs needs, and when.
Tripropylene glycol: one diol, many industrial roles
From architectural paint to photopolymer resins: what this oligomeric diol contributes, and what to verify before ordering a lot.
Dipropylene glycol: isomers, grades and what DPG means
One trade name covering several isomers and more than one grade. What actually distinguishes a drum fit for compounding work.
PGEE and water: tolerance, coupling and staying dry
One property explains most of what this solvent is bought for and most of what goes wrong with it: how it behaves…
Food grade propylene glycol: the raw material paperwork
What separates a food grade lot from a technical one, which documents travel with it, and who carries the finished product compliance.
Writing an enquiry that returns comparable quotations
Most chemical quotations cannot be compared because the enquiry did not make them comparable. The fix is in the document you send.
Same specification, different plant: what can still change
A specification is a filter, not a description. What moves when a material comes from a new site or a new route,…
