2-butene-1,4-diol

2-Butene-1,4-diol (CAS 110-64-5), also known commercially as Agrisynth B2D and 1,4-dihydroxy-2-butene, is a bifunctional allylic diol used as a building block and functional ingredient across personal care and food-related applications.

Its dual hydroxyl groups make it a reactive intermediate for synthesis as well as a direct-use humectant and flavoring component. In personal care formulations, it functions as a humectant to support moisture retention in skin and hair care products.

Food and flavor manufacturers use it as a flavoring agent and acidulant in finished formulations where controlled acidity and taste profile are required. As a synthetic intermediate, it serves in the production of specialty chemicals and polymers.

It is also utilized in fragrance compounds where the reactive double bond is a key point of chemical modification. Cosmetic formulators sourcing for moisturizing systems may evaluate it alongside conventional glycols for compatibility.

This chemical is available as a liquid at standard commercial purities suitable for industrial and specialty chemical use. Food-grade and technical-grade designations are the most commonly encountered specifications in the market.

It is typically supplied in drums or intermediate bulk containers depending on order volume. The material should be handled according to standard safety protocols for industrial diols to ensure product stability and performance.
