Cosmetic Grade Decyl Oleate-CAS 3687-46-5
Cosmetic Grade Decyl Oleate is a high-purity unsaturated synthetic ester emollient refined by professional esterification and multi-stage distillation purification technology. It is a high-grade skin-friendly cosmetic raw material different from traditional saturated ester emollients, with unique molecular flexibility and ultra-high skin lipid affinity.
It can deeply penetrate the skin stratum corneum, efficiently repair damaged skin barriers, replenish skin natural lipids, and fundamentally improve dry, rough and peeling skin conditions. It achieves a perfect balance of deep moisturizing and dry-touch non-greasy skin feeling, bringing delicate, soft and breathable skin texture without oily burden.
With excellent low-temperature fluidity, it ensures stable product texture in all seasons and avoids formula deterioration in low-temperature environment. In cosmetic formulas, it can significantly improve product ductility and powder dispersion uniformity, enhance makeup fitting and long-lasting performance. Featuring mild nature, low irritation, strong oxidation resistance and wide formula compatibility, it is an indispensable core raw material for high-end moisturizing repair and matte long-lasting makeup products.
Key Benefits
• Ultra-High Skin Affinity & Barrier Repair: Unsaturated molecular structure fits human skin lipids perfectly, stronger penetration than saturated esters, effectively repair dry damaged skin barrier and improve skin self-repair ability.
• Deep Penetrating Moisturizing & No Dry Rebound: Penetrate deep into the basal layer of the skin to replenish moisture and lock water for a long time, solve the problem of superficial moisturizing and easy dry rebound of ordinary emollients.
• Refreshing Dry-Touch & Zero Greasy Burden: Unique dry breathable texture, no oil shine or sticky residue after absorption, balance deep moisturizing and matte skin feeling, suitable for all seasons.
• Excellent Low-Temperature Fluidity & Seasonal Stability: No solidification or wax precipitation at low temperature, stable fluidity and formula texture throughout the year, no seasonal formula adjustment required.
• Optimize Makeup Fitting & Long-Lasting Performance: Excellent powder dispersion and lubricating properties, uniform makeup color, improve base makeup ductility and prevent floating powder and makeup removal.
• Mild Low-Irritation & Wide Compatibility: High-purity refined, non-sensitizing and non-comedogenic, friendly to sensitive and dry skin, fully compatible with all oil-phase systems for stable mass production.
Applications
• High-End Barrier Repair Skin Care: Core emollient for barrier repair cream, sensitive skin soothing lotion and dry skin intensive nourishing products, improve damaged skin and enhance skin tolerance.
• Four-Season Stable Moisturizing Series: Ideal raw material for all-season lotion and cream, solve the problems of thick and greasy in summer and solidified and poor fluidity in winter of traditional formulas.

• Q4: What is the difference between Decyl Oleate and saturated esters (IPP/Butyl Stearate)?
A4: Decyl Oleate is an unsaturated ester with flexible molecular structure, higher skin affinity and deeper penetrating repair ability than saturated esters. It has excellent low-temperature fluidity without seasonal formula changes, and balances deep moisturizing and dry-touch texture. Saturated esters focus on basic lubrication and moisturizing, while Decyl Oleate focuses on skin barrier repair and high-fit dry-touch skin feeling, more suitable for high-end repair and sensitive skin formulas.
• Q5: Is Decyl Oleate suitable for sensitive skin and acne skin?
A5: Yes. It is ultra-pure refined with mild properties, low irritation and non-comedogenic. It can soothe dry and fragile sensitive skin, repair damaged barriers without clogging pores, suitable for sensitive skin, acne-prone skin and dry skin long-term care.
• Q6: What are the formula matching notes?
A6: It is oil-phase raw material, recommended to add at 50-80℃ oil phase; stable under conventional cosmetic processing temperature; can be compounded with IPP, isooctyl palmitate, butyl stearate and silicone oil to balance lubrication, penetration and dry-touch matte feeling.
• Q7: Do you support stable large-batch supply all year round?
A7: Standardized synthesis and purification production lines ensure stable batch acid value, saponification value and iodine value, consistent product quality, sufficient inventory all year round, supporting long-term cooperative orders and customized formula matching services.
