Ascorbyl Tetraisopalmitate

Shaanxi Huatai Bio-fine Chemical Co. provides a premier, cosmetic-grade Ascorbyl Tetraisopalmitate (VC-IP) that serves as the gold standard for stable Vitamin C delivery. Our unique advantage lies in the molecule’s four-isopalmitate chain structure, which grants it extraordinary thermal and oxidative stability compared to other VC derivatives. This luxury active is our signature solution for “Brightening Oils” and “Waterless Serums,” providing brands with a potent, non-irritating, and highly bioavailable ingredient that converts effectively into pure Vitamin C within the skin.

1. Product Overview & Key Specifications

Ascorbyl Tetraisopalmitate is a stable, oil-soluble ester of Vitamin C. It is highly valued in professional skincare for its ability to deliver high concentrations of Vitamin C deep into the dermis without the acidity or irritation typically associated with L-ascorbic acid.

2. Technical Highlights & Critical Parameters

Our VC-IP is refined to ensure a clear, odorless liquid that does not impact the aesthetic of premium formulations.

• Purity: ≥ 98.0%

• Specific Gravity: 0.930 – 0.945

• Refractive Index: 1.459 – 1.465

• Heavy Metals: < 10 ppm

3. Mechanism of Action (MoA)

• Deep Penetration: The lipid-soluble nature allows the molecule to bypass the skin barrier efficiently.

• Intracellular Conversion: Once absorbed, it is enzymatically converted into free Vitamin C (Ascorbic Acid) to trigger biological functions.

• Collagen Synthesis: Stimulates the production of collagen and inhibits collagen degradation.

4. Core Advantages & Market USPs

• Extreme Stability: Remains stable at high temperatures and is resistant to oxidation/browning.

• Non-Irritating: Gentle on the skin even at high concentrations, making it suitable for sensitive skin products.

• UV Protection Synergy: Effectively reduces cell damage caused by UV radiation and inhibits melanogenesis.

5. Formulation Guidelines

• Recommended Usage: 1.0% – 3.0% (standard), up to 10% for intensive treatments.

• Processing: Highly oil-soluble; can be added directly to the oil phase.

• pH Range: Best used in formulations with a pH of 4.0 – 6.0.

6. Quality Assurance & Regulatory Confidence

Our manufacturing facility is ISO 9001/22000 and HALAL certified. We provide a full technical dossier, including COA and MSDS, ensuring our cosmetic-grade VC-IP meets the global regulatory standards for luxury cosmetics.

7. Recommended Synergistic Combinations

1. VC-IP + Bakuchiol: A powerful oil-based duo for anti-aging and skin texture refinement.

2. VC-IP + Ferulic Acid: To further boost antioxidant stability and photoprotection.

3. VC-IP + Glabridin: For high-end oil serums targeting deep-seated pigmentation.

8. Typical Applications & Success Stories

This ingredient is a core component in “Luxury Facial Oils,” “Anti-Aging Eye Creams,” and “Brightening Night Serums”. Brands using our VC-IP have achieved success in the premium market by claiming “High-Stability Vitamin C” without the typical scent or color issues.

9. Scientific Evidence & Literature Support

Scientific studies confirm that Ascorbyl Tetraisopalmitate has a higher percutaneous absorption rate than other Vitamin C derivatives. Internal lab trials show a significant reduction in UV-induced peroxide formation and a visible increase in skin radiance within 4 weeks.
