Dimethyl Sulfone
What is Dimethyl Sulfone?
Dimethyl Sulfone, also called methylsulfonylmethane (MSM), is a synthetic organic sulfur compound appearing as a white, crystalline, water-soluble powder. It forms via oxidation of dimethyl sulfoxide (DMSO), a byproduct in wood processing. In cosmetics, it serves as a multifunctional ingredient in water-based products like serums, gels, and lotions. Primarily acting as a solvent, it dissolves polar substances, enabling uniform blending of water-soluble actives and aiding controlled release. As a viscosity controlling agent, it modulates product thickness, enhancing spreadability, suspension of particles, and overall sensory feel. Its high solubility supports clear, lightweight formulations without greasiness, while chemical stability prevents degradation of sensitive components during storage.
