ZLEY®BIOCARE-PPD – Phenoxypropanediol (CAS 538-43-2):
マイルドで安全な製剤向けの、防腐剤を含まない抗菌相乗剤
製品概要
ZLEY®BIOCARE-PPD (INCI: Phenoxypropanediol, chemical name: 3-Phenoxy-1,2-propanediol) is structurally similar to Chlorphenesin. However, it is not classified as a traditional preservative but rather as a synergistic antimicrobial booster.
Phenoxypropanediol inhibits microbial growth by disrupting cell membranes, blocking the transport of cellular matrices in bacteria, and allowing the efflux of certain cellular components to impair normal bacterial metabolism.
As a potent broad-spectrum antimicrobial agent, it is effective against Gram-positive bacteria, Gram-negative bacteria, molds, and yeasts. It helps reduce the amount of other preservatives needed in formulations, making it an ideal choice for preservative-free concepts そして 敏感肌 applications.
ZLEY® is a professional supplier of Phenoxypropanediol (CAS 538-43-2), providing stable quality, technical support, and global delivery covering over 60 countries.
