Caprylyl Methicone (CAS 17955-88-3): Multifunctional Cosmetic Ingredient for Skincare & Makeup

1. Critical Specs: Precision for Reliable Formulations

• Purity ≥99.9%: Eliminates impurities (residual solvents, byproducts) to ensure batch-to-batch consistency, reduce skin irritation risks, and meet strict clean beauty standards.
• Refractive Index (25℃): 1.41–1.42 – Aligns with human skin’s natural refractive index (≈1.40–1.43), preventing "white cast" or chalkiness in sheer/makeup products and ensuring a seamless, natural finish.
• Specific Gravity (25℃): 0.83–0.84 – Ultra-lightweight, so it adds a silky, non-greasy feel to formulations—no heavy residue, even in cream-based products.
• Odourless: Won’t disrupt product fragrances, making it easy to integrate into scented skincare (e.g., lavender moisturizers) or fragrance-free sensitive-skin lines.

2. Core Role: Pigment Dispersant for Exceptional Makeup Performance

• Even Color Distribution: Breaks down pigment clumps (in foundations, concealers, blushes, eyeshadows) to eliminate streaks, patchiness, or faded spots—ensures every application has consistent, vibrant color payoff.
• Pigment Stability: Prevents pigment settling in liquid/cream bases, extending product shelf life and maintaining shade accuracy (no "separated" color in bottles).
• Simplifies Formulations: Reduces the need for extra dispersing agents, cutting ingredient costs while keeping formulas clean and easy to manufacture.

3. Versatile Applications: Skincare + Makeup

4. Why Formulators Choose It: Compliance & Consumer Appeal

• CAS 17955-88-3 Certified: Guarantees authenticity and alignment with global cosmetic standards (EU CosIng, US FDA), reducing regulatory risks for international product launches.
• Consumer-Centric Traits: Delivers the "lightweight, natural" feel modern users demand—critical for driving repeat purchases (especially in daily-use products like foundations or moisturizers).
• Universal Compatibility: Mixes seamlessly with silicones, oils, water-based actives, and pigments—no phase separation, saving R&D time spent troubleshooting formulation issues.
