Sinergista antimicrobiano sin conservantes para formulaciones suaves y seguras
Productos
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 y piel sensible applications.
