Sodium Guaiazulene Sulfonate
What is Sodium Guaiazulene Sulfonate?
Sodium guaiazulene sulfonate is a synthetic water-soluble salt derived from guaiazulene, a blue sesquiterpene hydrocarbon present in essential oils from plants like chamomile (Matricaria recutita) and guaiac wood (Guaiacum officinale). The sulfonate group enhances its aqueous solubility and stability, allowing incorporation into clear cosmetic formulas where it imparts a subtle blue hue. Commonly found in hair care products such as shampoos and conditioners, as well as facial and body cleansers, it functions primarily as a surfactant. By lowering surface tension at interfaces, it promotes the formation of foam, aids in dirt and oil removal, and supports emulsification of oils in water-based systems. Its mild profile suits formulations targeting sensitive skin or scalp, contributing to overall product gentleness without harsh effects.
