Aper\u00e7u du produit<\/strong><\/strong><\/h3>\n\n\n\n

ZLEY\u00aeBIOCARE-PPD (INCI: Phenoxypropanediol, chemical name: 3-Phenoxy-1,2-propanediol) is structurally similar to Chlorphenesin. However, it is not classified as a traditional preservative<\/strong> but rather as a synergistic antimicrobial booster<\/strong>.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

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<\/strong> et peau sensible<\/strong> applications.<\/p>\n\n\n\n

ZLEY\u00ae is a professional supplier of Phenoxypropanediol (CAS 538-43-2), providing stable quality, technical support, and global delivery covering over 60 countries.<\/p>\n\n\n\n
