Solubilizers

Solubilizers are clear to slightly viscous liquids that help disperse oil-soluble ingredients into water-based formulations. They are essential in micellar waters, serums, and body sprays to maintain clarity and even distribution of active ingredients. 

Popular INCI ingredients in this segment include PEG-40 hydrogenated castor oil and Polysorbates. The industry is shifting toward PEG-free and biodegradable alternatives. Regulatory guidelines focus on their safety in both leave-on and rinse-off formulations.
