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

Ascorbyl Palmitate is the palmitic ester of ascorbic acid. In emulsions and anhydrous oils it is used as an oil-phase antioxidant, not as a water-soluble vitamin C salt. This grade is a white to yellowish powder that disperses in oils.

Creams and balms continue to specify this INCI when the oil phase needs antioxidant protection. Cosmetic-grade Ascorbyl Palmitate remains a high-volume bulk ester when the assay is on the COA.

Key Benefits & Applications

Ascorbyl Palmitate is an oil-soluble vitamin C ester used to protect the oil phase.

• Added to the oil phase of creams, lotions, and balms
• Does not replace a water-phase vitamin C salt
• Fits anhydrous oils that need an antioxidant powder
• Pairs with tocopherol when the oil phase uses both esters
• Typical use level: 0.01–0.2% in the finished formula

Formulation Guidelines

Follow these guidelines to melt Ascorbyl Palmitate into the oil phase.

• Suggested Use Level: Typical 0.01–0.2% in the finished formula
• pH Range: Suggested 4.0–7.0 for the finished emulsion
• Addition: Disperse in the oil phase with mild warming; it does not dissolve in water
• Stability: Protect from light and air; avoid prolonged high heat
• Combine with Tocopherol when the oil phase needs both this ester and free tocopherol.
