Description
Products Description
Liquid Germall Plus is a synergistic preservative blend combining diazolidinyl urea (a formaldehyde-releasing preservative effective against gram-positive and gram-negative bacteria) with iodopropynyl butylcarbamate (IPBC, which extends coverage against yeasts and molds), carried in a propylene glycol base. This combination has become one of the most widely specified broad-spectrum preservative systems in cosmetic and personal care formulation, valued for its effectiveness across a wide pH range and compatibility with nearly all common cosmetic ingredient categories.

Products Description
Liquid Germall Plus is valued mainly for its broad-spectrum, synergistic antimicrobial activity, which underpins its widespread use across cosmetic formulation:
1. Broad-Spectrum Microbial Protection
The combination of diazolidinyl urea and IPBC provides coverage against gram-positive and gram-negative bacteria, yeasts, and molds in a single preservative system.
2. Wide pH Compatibility
Effective across a pH range of 3–8, it supports use in a wide variety of formulation types without requiring pH-specific preservative adjustments.
3. Broad Formulation Compatibility
Its compatibility with cationic, anionic, and nonionic systems, along with water-in-oil and oil-in-water emulsions, makes it a flexible choice across product categories.
4. Cost-Effective at Low Use Levels
Its effectiveness at low concentrations (0.1%–0.5%) makes it an economical preservation solution, and it can also be used to reinforce other preservative systems.

FAQ
Q: What is the recommended use level and how should it be added to a formulation?
A: Recommended use level is 0.1%–0.5% (up to 1% for complex formulations). It should be added during the cool-down phase of formulation at 50°C (122°F) or below to avoid compromising efficacy.
Q: What is your MOQ for wholesale orders?
A: MOQ typically starts from 1kg for trial/formulation-testing quantities, with larger volumes available for commercial orders.
Q: Does this product require preservative challenge testing?
A: Yes - as with any preservative system, we recommend formulators conduct a preservative efficacy/challenge test on the finished formulation to confirm adequate protection at the specific use level and formulation matrix.
Q: What documentation do you provide?
A: COA, MSDS, technical data sheet, and regulatory compliance documentation (including INCI declaration and IPBC concentration calculations) are provided per batch/order.
Q: Is this preservative approved for use in major markets?
A: At the standard recommended use levels, it is formulated to comply with regulatory limits in the US, EU, and Japan - but formulators should confirm compliance for their specific target market and finished product category, as regulations can vary and change.
