BAC Bacteriostatic Water
(Special Bacteriostatic Solvent Raw Material for Lyophilized Powder)
Product Overview
BAC Bacteriostatic Water is prepared with water for injection supplemented with pharmaceutical-grade benzyl alcohol. It is a colorless, clear liquid raw material. Adopting aseptic preparation technology, it serves as supporting solvent for various lyophilized powder, especially suitable for filling of dual-chamber isolation vials.
The system delivers persistent bacteriostatic capacity, inhibiting microbial growth after lyophilized powder reconstitution and preventing rapid deterioration of active raw materials. Compatible with lyophilized powder systems including recombinant protein, PDRN, NAD⁺ and regenerative microspheres, it is a mainstream supporting solvent for medical aesthetic lyophilized powder.
Core Technology
Aseptic preparation & filtration technology: multi-stage sterile filtration to guarantee low microbial load
Precise ratio control technology: balance bacteriostatic efficiency and biocompatibility to reduce cellular irritation
Stable clarification system technology: keep transparent during long-term storage without precipitation or stratification
Support large-scale aseptic filling for dual-chamber vials
Mechanism of Action
Benzyl alcohol inhibits reproduction of gram-positive and gram-negative microorganisms, slowing contamination after powder reconstitution. High-purity water fully dissolves lyophilized active substances and ensures uniform dispersion of peptides, proteins and nucleotides. The mild liquid carrier reduces denaturation risk and stabilizes original structure of active ingredients.
Core Advantages
Colorless transparent liquid with excellent solubility for various lyophilized powder
Built-in bacteriostatic property extends service life of reconstituted solution
Good biocompatibility, suitable for post-procedure skincare and sensitive skin formulations
Compatible with ordinary vials and dual-chamber regenerative packaging
Matches most lyophilized active materials such as NAD⁺, rh-EGF, PDRN, recombinant collagen and silk fibroin
Application Scenarios
Supporting solvent for dual-chamber lyophilized powder, solvent for salon lyophilized powder, raw material for medical aesthetic lyophilized formulations, OEM repair lyophilized powder system, dedicated reconstitution solvent for peptide & protein lyophilized preparations
