What Is PEG-5 TRIMYRISTYL CITRATE?

PEG-5 TRIMYRISTYL CITRATE 是一种PEG化柠檬酸三酯（Tri-alkyl Citrate PEG Ether），由柠檬酸与肉豆蔻酸（myristic acid）酯化后再与PEG-5醚化制得。作为多功能润肤剂和增塑剂，提供中厚肤感，兼具乳化辅助功能。柠檬酸骨架赋予良好的皮肤兼容性和轻微去角质潜力。(PEG-5 TRIMYRISTYL CITRATE is a PEGylated tri-alkyl citrate ester. As a multifunctional emollient and plasticizer, it provides a 中厚 skin feel with co-emulsifying properties. The citrate backbone offers good skin compatibility and mild exfoliating potential.)

Key Skin Benefits

+ 润肤肤感 — 中厚触感，适合不同产品类型 (Emollient feel — 中厚 touch, suitable for various product types)
+ 增塑/柔顺 — 在发用产品中提供柔韧性 (Plasticizing/softening — provides flexibility in hair products)
+ 柠檬酸骨架 — 天然来源的酸基质，良好皮肤兼容 (Citrate backbone — naturally-derived acid base, good skin compatibility)

Pros

+ 多功能 — 兼具润肤、增塑和辅助乳化 (Multifunctional — emollient, plasticizer, and co-emulsifier)
+ 肤感可调 — 通过选用不同脂肪酸链调节肤感 (Tunable feel — different fatty acid chains adjust skin feel)
