Where is Vitamin B6 Pyridoxine Dipalmitate used?

• Personal care and cosmetics: multifunctional profile in anhydrous and emulsion systems
• Creams, serums and hair-conditioning products: mild lubricity and skin-feel optimization
• Humectant and moisture retention at the skin surface
• Antioxidant character stabilises sensitive formulations against oxidative degradation
• Food, nutraceutical and supplement manufacturing: fat-soluble delivery route for Vitamin B6 activity
• Lipid-based soft-gel capsules, oily suspensions and nutricosmetic formulations where water-soluble pyridoxine forms present compatibility challenges
• Its stability profile in fatty matrices reduces the need for additional antioxidant loading.
