2-Ethylhexyl Salicylate (Octisalate)-CAS 118-60-5
Cosmetic Grade 2-Ethylhexyl Salicylate (Octisalate) is a high-purity oil-soluble chemical UVB sunscreen filter, which is one of the most classic, safe and widely used sunscreen raw materials in the global cosmetic industry. With a specific UVB selective absorption band, it can effectively capture and isolate medium-wave ultraviolet rays that cause skin sunburn, redness and light aging, forming a reliable external light protection barrier for the skin.
Different from high-irritation strong-effect sunscreen agents, octisalate features mild molecular properties, low skin irritation and excellent photostability, which will not cause burden or sensitization to the skin. In compound sunscreen formulas, it not only provides stable UVB protection, but also acts as an efficient solubilizer and stabilizer.
It can perfectly dissolve various insoluble solid sunscreen filters, improve formula clarity and uniformity, prevent long-term storage precipitation and stratification, and significantly enhance the durability and efficacy stability of finished sunscreen products. With mature application technology, high safety and strong formula adaptability, it is an indispensable core basic raw material for daily civilian and outdoor high-power sunscreen products.
Key Benefits
• Precise UVB Barrier, Prevent Light Aging: Specifically absorb harmful UVB ultraviolet rays, effectively avoid skin sunburn and redness, inhibit epidermal photoaging, and maintain skin youthful state.
• Mild & High Safety, Wide Audience: Compliant with EU and US cosmetic standards, non-irritating and non-sensitizing, suitable for sensitive skin and general population daily sunscreen formulas.
• Powerful Solubilization & Clarification Effect: Excellent solubility for solid sunscreen powders, solve formula turbidity and precipitation problems, keep sunscreen products clear and transparent.
• Enhance Formula Photostability: Effectively delay the photolysis failure of compound sunscreen components, stabilize overall sunscreen efficacy, and extend product effective protection time.
• Excellent Skin Feeling & Film-forming Property: Good spreadability, non-greasy and non-sticky, help form uniform and breathable sunscreen film, optimize product wearing experience.
• Stable Performance & Easy Formulation: Not easy to oxidize and decompose, wide pH and temperature adaptability, compatible with most oil-soluble sunscreen agents, suitable for mass industrial production.
Applications
• Daily Civilian Sunscreen Products: Core UVB protective ingredient for daily low-power and mild sunscreen lotion and cream, meet daily indoor and outdoor light protection needs.
• Outdoor High-power Sunscreen Series: Compounded with UVA filters to build full-band UVA/UVB protection system, suitable for high SPF/PA outdoor long-acting sunscreen products.
• Transparent & Lightweight Sunscreen Formulas: Used as solubilizer and stabilizer for transparent sunscreen gel and lightweight sunscreen milk, ensure formula clarity and long-term stability.
• Sunscreen Makeup Base & Isolation Products: Added in sunscreen primer and isolation cream, provide mild daily light protection, optimize product texture and ductility.
• Post-sun Repair & Maintenance Products: Assist in soothing light damage, cooperate with repairing ingredients to stabilize skin state, and prevent secondary light aging damage.
• Compound Full-band Sunscreen System: Perfectly compounded with avobenzone, octyl methoxycinnamate and other sunscreen agents to achieve full-band ultraviolet shielding and efficacy superposition.
