Grape Seed Procyanidin Sunscreen Compound-CAS 84929-27-1
Grape Seed Procyanidin Sunscreen Compound is a high-value plant-derived compound functional raw material specially developed for sunscreen system upgrading.
Different from single-effect antioxidant or single auxiliary sunscreen raw materials on the market, this product adopts a scientific compound formula ofhigh-activity procyanidins + plant UV-resistant active substances, realizing dual core upgrading of sunscreen "efficacy stability and skin protection".
On the one hand, it exerts the dominant advantage of procyanidins' super antioxidant capacity, efficiently scavenges photooxidative free radicals, inhibits skin light aging, and solves the problem of aging and dullness after sun exposure caused by insufficient antioxidant capacity of traditional sunscreens.
On the other hand, it assists in shielding full-band ultraviolet rays, optimizes the formula protection spectrum, significantly improves the photolysis resistance of chemical sunscreen agents, avoids the decline of sun protection factor caused by long-term outdoor exposure, and greatly improves the durability and practicability of sunscreen products.
With natural mild attributes and wide formula compatibility, it is compatible with water-soluble, oil-soluble and physical sunscreen systems, and is an indispensable multi-effect synergistic raw material for new generation high-stability anti-photoaging sunscreen products.
Key Benefits
• Plant Compound Formula, Ultra-Mild & High Safety: Pure natural plant compound components, no chemical irritating additives, no sensitizing and corrosive ingredients. After professional purification and compounding treatment, it has extremely low skin irritation, safe and mild, perfectly suitable for sensitive skin, pregnant women and high-standard clean sunscreen formulas.
• Super Strong Antioxidant Capacity, Inhibit Photoaging Fundamentally: Procyanidins have excellent free radical scavenging efficiency, which is far higher than conventional antioxidant ingredients such as VC and VE. It can comprehensively eliminate UVA/UVB-induced oxidative free radicals, block lipid peroxidation, inhibit skin sagging, fine lines and dull yellowness caused by light aging, and maintain youthful skin state.
• Auxiliary Full-Band UV Shielding, Complement Protection Blind Areas: Possess balanced UVA long-wave and UVB medium-wave auxiliary absorption capacity, make up for the insufficient protection spectrum of single sunscreen agents, realize more three-dimensional and comprehensive full-spectrum protection, and effectively reduce sunburn and tanning risks.
• Significantly Improve Photostability, Long-Lasting Anti-Photolysis: Effectively restrain the photolysis and inactivation of chemical sunscreen filters under strong light, stabilize the SPF/PA value of finished products, avoid rapid attenuation of sun protection efficacy during outdoor activities, and greatly extend the effective sun protection duration.
• Dual-Phase Compatibility, Wide Formula Adaptability: Compatible with water-phase, oil-phase and water-oil compound sunscreen systems, perfectly matched with physical sunscreen powder and various organic sunscreen agents. It will not conflict with the formula system, effectively optimize product texture and improve formula stability.
• Sun Protection + Anti-Oxidation + Repair Multi-Effect Integration: Break the single functional limitation of traditional sunscreen additives. While stabilizing sun protection efficacy, it repairs mild sun damage, relieves skin dryness and dullness after sun exposure, and comprehensively improves the comprehensive protection and skincare value of sunscreen products.
Applications
• Outdoor Long-Lasting Stable Sunscreen Series: Core photostability synergistic raw material for outdoor sports, travel and high-exposure scenario sunscreens. It solves the problem of rapid efficacy attenuation of ordinary sunscreens under strong light, and realizes all-day stable full-spectrum protection.
• High-End Anti-Photoaging Sunscreen Products: Exclusive functional component for anti-light-aging sunscreen cream and lotion. It combines sun protection and anti-oxidation, fundamentally inhibit skin photoaging, and improve the anti-aging attribute of sunscreen products.
• Sensitive Skin Mild Sunscreen Series: Preferred natural synergist for mild low-irritation sunscreen formulas. Plant-derived mild ingredients reduce formula irritation, balance sunscreen efficacy and safety, and are suitable for long-term daily sun protection of fragile skin.
• Water-Oil Compound Full-Spectrum Sunscreen: Key upgrading raw material for compound sunscreen systems, cooperating with water-soluble and oil-soluble sunscreen agents to optimize protection spectrum, eliminate blind areas, and improve overall protection level and durability.
• Sun Protection & Repair Integrated Products: Applied in multi-functional sunscreen products with post-sun soothing and repair efficacy, relieve mild sun damage, improve post-sun skin dullness, and realize integrated protection and repair.
• Daily Light Anti-Light-Damage Skincare Series: Suitable for daily isolation sunscreen, light facial sunscreen and daily anti-oxidation protection skincare products, improving daily light damage defense ability.
