Appearance: White to off-white powder.

Description

Sodium ascorbyl phosphate (SAP) is used as a stabilized source of vitamin C in cosmetic products. SAP is the stabilized (phosphorylated) sodium salt of L-ascorbic acid that does not degrade in formulas containing water. Esterification of asorbic acid protects vitamin C from destruction by oxidation. Light-stable and oxygen-stable. White-to off-white powder, mild odor.

This is a cosmetic raw material and is meant for external use only in cosmetic formulations.

Typical usage rate:  0.2 – 3, up to 10%
Solubility:  Soluble in water (clear solution at 10% concentration), mix well, allow time for lumps to dissolve

Formulation Guidelines

• SAP may discolor in formulations with a pH below 6, so is best used in products with a final formulation pH between 6.0 – 7.0.
• You can pre-disperse it in a small amount of distilled water and add at the end of the formulation process.

Applications

• Suncare and after-sun products
• Makeup products
• Skin lightening products
• Anti-aging products
• Creams and lotions
