1,3 Butylene Glycol

1,3-Butylene Glycol is a hardworking, non-irritating multitasker. As a humectant it holds moisture in the skin; as a solvent it helps dissolve and carry other actives; and it improves the slip, texture and overall feel of creams, lotions and serums. It is water-soluble, gentle enough for sensitive skin and suits every skin type.

• Usage rate: 1%–5%
• Solubility: water-soluble — add to the water phase
• Texture: gives a smoother, more spreadable feel
• Pairs well with: most actives (it helps dissolve and carry them)

External use only — for cosmetic formulation. Work with a chemist or formulator if you are new to formulating.
