Comparison ArticleOne is a capped broad-spectrum preservative, the other a multifunctional humectant with mild preservation. The difference decides your label claim as much as your shelf life.
Material GuideWhere glycerin helps, where it reverses and dries skin, and why the grade on the CoA matters more than the price per drum.
Process GuideWhat a challenge test proves, what it does not, and how to read a supplier claim that a preservative system passes at a given dosage.

The Anhui Xiwe technical and trade team, using the product documentation behind the ingredients we actually ship.
The dosage ranges and limits quoted come from product documentation. Verify them against the regulation in your destination market before you use them in a specification.

Send the formulation context and the market you sell into. A specialist replies within 24 hours, and the answer will say plainly when the right ingredient is not one of ours.
