Our direct factory supply model delivers reliable bulk quantities with full technical documentation and free sample support.

Retinal is vitamin A aldehyde, used in leave-on renewal and anti-wrinkle care. It is not a colorant. The material is a yellow to orange crystalline powder that dissolves in oils and ethanol and is insoluble in water. It is sensitive to light and air.

Night serums and retinal creams continue to specify this INCI because the assay and the low dose can be checked on the COA. Cosmetic-grade Retinal remains a high-interest bulk active for renewal systems.
