Emollient Comparison: Triglycerides, Synthetic Esters & Silicones
2026-04-15
Why are High-Quality Emollients Critical for Skincare, Sunscreens, and Color Cosmetics?
Cosmetic emollients are a core component of formulation systems, serving important functions such as moisturizing the skin, enhancing texture, dissolving sunscreen agents, dispersing pigments, and stabilizing the formulation. As consumer demand for products that are light and non-greasy, gentle and safe, and eco-friendly continues to grow, formulators are becoming increasingly selective in their choice of oil ingredients.

Classification & Introduction Triglycerides, Synthetic Esters, Volatile Cyclic Silicones, and Phenyl Trimethicone
Ingredient Category | Product Name (CAS No.) | Features & Positioning | Typical Applications |
|---|---|---|---|
Triglycerides — Basic Fresh Moisturizing Base | Caprylic/Capric Triglyceride (CAS 94109-09-8) | Mild, skin-friendly, fresh and non-greasy; the first choice for basic oil phase in formulations | Lotions, creams, serums, baby skincare products |
Lightweight Synthetic Esters — Preferred for High Spreadability & Silicone Replacement | Coco-Caprylate/Caprate (CAS 95912-86-0) Cetyl ethylhexanoate (CAS 59130-69-7) | Extremely fresh, fast-absorbing, high spreadability, low greasiness; ideal alternative to D4/D5 in silicone-free formulations | Sunscreens, lightweight serums, color cosmetics |
Volatile Cyclic Silicones — Extremely Fresh & Fast-Drying Skin Feel | Silky skin feel, fast volatilization, significantly improving application texture; restricted by regulations in some regions, gradually replaced by synthetic esters | Skincare products, sunscreens, hair care products, color cosmetics | |
Phenyl-modified silicones—high-end gloss & Silky Skin Feel | High gloss, luxurious and silky skin feel; used to enhance texture and grade of products | High-end skincare products, hair care products, foundation, lip products |
Deep Comparison and Substitution Relationship of Similar Cosmetic Ingredients
Ingredient Category | Product Name | Key Features & Positioning |
Triglycerides (GTCC vs. glyceryl tri(2-ethylhexanoate)) | Caprylic/Capric Triglyceride (GTCC) | Classic basic emollient oil with high cost performance |
Glyceryl tri(2-ethylhexanoate) | Fresher, smoother, and more high-end skin feel | |
Synthetic Esters (Coco Ester, INI, Cetyl Ethylhexanoate) | Coco-Caprylate/Caprate | Strong plant-derived scent, fresh and mild |
Isononyl Isononanoate (INI) | Extremely fresh, strong solubility, preferred for sunscreens | |
Cetyl ethylhexanoate | High silkiness, commonly used in color cosmetics | |
Silicones (D4, D5, Phenyl Trimethicone) | All three are star products for silicone substitution; they can replace D4/D5 and be used alternately according to application scenarios (sunscreen, makeup, etc.) | Strong volatility, traditional fresh raw materials, but affected by regulations |
Phenyl Trimethicone | High-end skin feel, non-volatile, more stable | |
High-grade Esters | Dipentaerythrityl Pentaisononanoate | High purity, high stability, low viscosity; suitable for high-end formulations, long-lasting moisturization, non-greasy, ideal for anti-aging, repair and luxurious texture systems |
FAQ
What is the difference between isononyl isononanoate and coco-caprylate/caprate?
Both are lightweight synthetic esters. Isononyl Isononanoate (INI) has stronger solvency and is more suitable for sunscreens. Coco-Caprylate/Caprate is milder and offers better skin-friendly sensory properties.
Which ingredients can replace D4/D5 silicones?
Coco-Caprylate/Caprate, Isononyl Isononanoate, and Cetyl Ethylhexanoate are the most mature green alternatives for D4/D5 silicones available today.
Which emollients are suitable for sensitive and acne-prone skin?
GTCC, Coco-Caprylate/Caprate, and INI are mild and non-comedogenic and are preferred choices for sensitive and acne-prone skin.
