PEG-66 TRIHYDROXYSTEARIN

What Is PEG-66 TRIHYDROXYSTEARIN?

PEG-66 TRIHYDROXYSTEARIN 是一种PEG化三羟基硬脂酸甘油酯（Polyglyceryl-3 alternative），由氢化蓖麻油衍生的三羟基硬脂酸与PEG-66酯化制得。作为水溶性增稠剂和凝胶剂，提供透明或半透明的凝胶质地。中等PEG链提供良好的亲水-疏水平衡，适合乳霜和乳液增稠。(PEG-66 TRIHYDROXYSTEARIN is a PEGylated trihydroxystearin derived from hydrogenated castor oil. As a water-soluble thickener and gelling agent, it provides clear to translucent gel textures.)

Key Skin Benefits

• + 高效增稠 — 水相增稠，不需额外乳化 (Efficient thickening — thickens the water phase without extra emulsification)
• + 透明凝胶 — 可制备透明啫喱产品 (Clear gel — enables transparent gel formulations)
• + 蓖麻油来源 — 氢化蓖麻油是可再生植物资源 (Castor-derived — hydrogenated castor oil is a renewable plant resource)

Pros

• + 植物来源 — 蓖麻油衍生物 (Plant-derived — castor oil derivative)
• + 冷配可用 — 不需加热即可分散 (Cold-processable — can be dispersed without heating)
• + 透明配方 — 适合啫喱和精华 (Transparent formulas — suitable for gels and serums)

Cons

• − 含PEG — 涉及环氧乙烷 (Contains PEG — involves ethylene oxide)
• − 高浓度粘腻 — 过量使用产生粘感 (Sticky at high concentration — overuse causes tackiness)
• − 电解质敏感 — 高盐配方可能影响增稠 (Electrolyte sensitive — high-salt formulas may affect thickening)
