Ascorbyl Tetraisopalmitate VC-IP High-Stability Oil-Soluble Whitening Antioxidation Anti-Aging Cosmetic Raw Material(CAS 183476-82-6)
Ascorbyl Tetraisopalmitate (VC-IP) is a flagship high-stability lipophilic vitamin C derivative in high-end skincare, solving the core industry pain points of traditional water-soluble VC such as easy oxidation, discoloration, poor penetration and irritability.
With a unique four-isopalmitate modified lipophilic structure, it has excellent skin penetration, can cross the skin sebum barrier efficiently, and continuously decompose into active vitamin C in the dermis, achieving deep-layer brightening, long-acting anti-oxidation and endogenous anti-aging.
Different from ordinary VC derivatives with superficial efficacy, VC-IP realizes whole-layer skin whitening and anti-aging from stratum corneum to dermis.
It inhibits melanin production to brighten dull skin, scavenges free radicals to resist photo-oxidation aging, stimulates collagen synthesis to improve sagging fine lines, and repairs UV-induced skin damage.
With ultra-high formula stability, no yellowing and no inactivation, mild and non-irritating, it is the preferred upgraded core active for high-end stable brightening and anti-aging skincare formulas.
Key Benefits
• Ultra-High Stability, No Formula Yellowing: Breaking the instability limitation of traditional VC, it has excellent light and thermal stability, not easy to oxidize and inactivate under high temperature and strong light environment. It can long-term maintain clear formula state without yellowing and discoloration, perfectly solving the shelf-life color change problem of VC skincare products.
• Lipophilic Deep Penetration, High Utilization Rate: Unique oil-soluble structure fits the skin sebum barrier perfectly, efficiently penetrates into the deep dermis, avoids superficial ineffective retention, continuously converts into active VC in the skin, and greatly improves the bioavailability of vitamin C.
• Source Inhibit Melanin, Stable Brightening: Effectively inhibit the activity of tyrosinase, block the oxidative polymerization of melanin from the source, fade sun tan, dull yellow and uneven skin tone, achieve uniform and natural brightening effect, and avoid whitening rebound and blackening.
• Efficient Anti-Oxidation, Repair Photoaging: Powerful free radical scavenging capacity, specifically neutralizes ultraviolet-induced photo-oxidative free radicals, reduces skin light damage, delays light aging and endogenous aging, fades fine dry lines caused by oxidation, and maintains youthful skin texture.
• Boost Collagen Synthesis, Firm Anti-Aging: As a core collagen synthesis cofactor, it stimulates dermal fibroblast activity, promotes collagen and elastin regeneration, improves facial sagging and loose contour, and realizes long-term firming and anti-wrinkle effect.
• Mild & Wide Compatibility, Easy Formula Upgrade: Non-irritating and non-sensitizing, suitable for sensitive skin and long-term maintenance. Compatible with oil-water dual systems, can be freely compounded with whitening, antioxidant and anti-aging ingredients to build a stable and efficient brightening anti-aging closed-loop system.
Applications
• High-Stability Whitening & Brightening Series: Core active ingredient for high-end stable whitening products, solving the problem of easy yellowing and instability of traditional VC formulas, achieving long-term uniform brightening effect.
• Photoaging Repair & Sun Care Products: Exclusive light damage repair active for sun-exposed skin, resist ultraviolet oxidation, fade sun tan and sunburn dullness, prevent photoaging pigmentation.
• Multi-Effect Anti-Aging Firming Series: Key collagen-boosting raw material for anti-aging formulas, combining anti-oxidation, brightening and firming efficacy to improve aging dullness and sagging problems in all dimensions.
• Oil-Soluble High-Efficiency VC Formula: Preferred substitute for traditional unstable VC, suitable for essence oil, cream, oil-based skincare and other oil-phase system products.
• Dullness & Sallowness Repair Skincare: Targeted active for improving staying-up dullness, facial sallowness and uneven skin tone, restore skin transparent and bright state.
• Mild Long-Term Skin Maintenance Products: Safe and mild brightening anti-aging active for daily skin maintenance, suitable for sensitive skin and fragile skin long-term gentle care.
