3-METHOXYBUTANOL.

Optional CAS 2517-43-3 / SOLVENT

3-Methoxybutanol is a specialized glycol ether that serves as a high-performance solvent and coupling agent in skincare formulations. It excels at bridging water and oil-based ingredients while controlling product viscosity and enhancing the delivery of fragrance components. This multifunctional ingredient helps create smoother, more spreadable textures with improved sensory properties.

Summary

Solvent Viscosity controlling Fragrance carrier

Science

Mechanism of Action

Functions as a molecular mediator that improves solubility between hydrophobic ingredients like oils and fragrances within water-based systems. It regulates evaporation rates of volatile components for enhanced scent longevity while reducing viscosity to optimize product flow and spreadability on skin.
