Glycols, polyglycols and their ethers and ether acetates — properties, grades and where each one fits in a formulation.

Application notes, material explainers and process guidance written around the chemicals we manufacture and export.

Why the label says only harmful if swallowed, what the body turns diethylene glycol into, and why the effect is delayed.

n-Butanol (CAS 71-36-3) is bought for two unrelated jobs: tail solvent in coatings and inks, and feedstock for butyl esters and glycol…

How the two production routes shape the impurity profile, why the water azeotrope sets the price ladder, and what to order.

Polyols arrive as syrups, crystals and granulates that behave very differently. A supply-side look at the family and its handling.

Sorbitol as a raw material: crystallising and non-crystallising syrups, powder grades, and the limits that matter on a certificate.

A raw-material supplier answers questions about sorbitol with identity, authorisation and lot documents, not with claims. Here is that file.

Glycerol reaches the same monograph from vegetable, animal and synthetic routes. What origin changes, and which declarations buyers ask for.

Glycerol itself is benign. The harm on record came from adulteration, grade mismatch and overheating, not from the molecule.

Glycerin is harmless or lethal depending on one limit test. Which grade to order, what a certificate must prove, and where the…
