Thiamine Hydrochloride

What is Thiamine Hydrochloride?

Thiamine Hydrochloride is the water-soluble hydrochloride form of thiamine, an essential B vitamin originally identified for its role in energy metabolism. In cosmetics, it primarily serves in skincare and haircare products as a multifunctional additive. Chemically, it acts as a humectant by drawing moisture to the skin's surface, supporting suppleness and smoothness without greasiness. It also neutralizes off-putting scents from raw materials, ensuring a more agreeable product aroma. This ingredient thrives in aqueous-based formulations like lotions, gels, and cleansers, where it aids in stabilizing sensory qualities. Derived synthetically for purity and consistency, it integrates seamlessly into diverse product types focused on everyday maintenance.
