What Is Liquid Germall Plus?
Liquid Germall Plus is a well-known synergistic paraben-free liquid preservative blend for cosmetic industry. It combines diazolidinyl urea and iodopropynyl butylcarbamate (IPBC) dissolved in propylene glycol solvent. Two active ingredients work synergistically to deliver broad-spectrum anti-microbial protection against gram-positive bacteria, gram-negative bacteria, yeast and mold at low addition dosage.
It is fully water-miscible and works across wide pH 3.0-8.0 range. It fits most aqueous solutions and O/W emulsion cosmetic systems, both for leave-on and rinse-off products. Different from single-component preservatives such as phenoxyethanol, Liquid Germall Plus covers bacteria, yeast and mold simultaneously without high-dosage addition. It is widely adopted by small-batch formulators and large cosmetic manufacturers. Aogebio supplies high-purity cosmetic-grade Liquid Germall Plus in bulk, offering free samples, full qualification documents and global one-stop shipping services for cosmetic manufacturers.
Core Advantages Of Our Liquid Germall Plus
Synergistic Broad-Spectrum Anti-Microbial Performance
Combination of two active substances produces synergistic anti-microbial effect. Effectively inhibits bacteria, yeast and mold with low usage level, provides complete preservation protection for water-containing cosmetic formulas.
Wide pH Compatibility Range
Maintain stable anti-microbial efficacy within pH 3.0-8.0, suitable for acidic serum, neutral lotion and weakly alkaline hair-care products, without strict pH adjustment requirement before application.
Good Water-Soluble & Easy Formulation Operation
Transparent water-soluble liquid, easy to disperse into water-phase or cooling emulsion system, no complicated solubilizing procedure, friendly for industrial production and laboratory small-batch trial.
Excellent Ingredient Compatibility
Compatible with anionic, non-ionic, amphoteric surfactants, plant extracts, proteins, thickeners and most cosmetic active raw-materials. Its anti-microbial performance will not be easily interfered by common cosmetic components.
Paraben-Free & Cost-Effective Low-Dosage Usage
Paraben-free preservative solution, effective at low dosage 0.1-0.5%, brings low formula cost, meets many clean-beauty formula development requirements.
Stable Batch Quality & Flexible Supply
Consistent batch-to-batch active ingredient content and physical-chemical indicators, fit for large-scale industrial production; support sample testing, small-batch trial order and large-volume bulk customization.
How Liquid Germall Plus Works In Cosmetic Formulations
Diazolidinyl urea mainly inhibits bacterial reproduction, while IPBC strongly restrains yeast and mold growth. Two ingredients work synergistically to realize full-range anti-microbial protection in water-containing cosmetic systems.
Liquid Germall Plus should be added into formula cooling phase below 50℃, high temperature will cause IPBC degradation and reduce anti-mold efficacy. After uniform dispersion in aqueous or emulsion system, active molecules distribute throughout whole formula matrix, suppress microbial reproduction, prevent cosmetic product contamination, spoilage, turbidity and odor deterioration, extend finished-product shelf-life.
Important regulatory reminder: Please comply with regional cosmetic regulatory limits for IPBC content, especially EU restriction for leave-on facial products. Not recommended for lip products and eye-area high-risk formulas.
Main Functions & Cosmetic Application Fields

Formulation Guide: Dosage, Solubility & Matching Tips
Recommended dosage (based on commercial Liquid Germall Plus raw liquid):
- -Pure aqueous system (toner, serum): 0.1%-0.3%
- -O/W lotion & cream regular formula: 0.2%-0.4%
- -Formulas rich in plant extracts / botanical infusions: 0.3%-0.5%
Solubility: Fully water-soluble; add to water-phase or emulsified cooling-phase, not suitable for pure oil-phase anhydrous formulas.
Recommended matching ingredients: Glycerin, panthenol, xanthan gum, carbomer, various anionic/amphoteric/non-ionic surfactants, plant extracts.
Formulation Notes:
- -Must add at cooling phase when formula temperature ≤50℃; high temperature above 50℃ will degrade IPBC component and weaken anti-mold performance.
- -Must be uniformly stirred after addition to avoid local high-concentration spot.
- -Pay attention to regional regulatory requirement for IPBC maximum allowable concentration, especially EU cosmetic regulations.
- -Not suggested for lip balm, lip gloss and eye-contact cosmetic products.
- -Not applicable for 100% anhydrous oil-only formulas, it requires water-containing environment to exert preservative effect.
- -Seal and store under cool, dark condition; avoid high-temperature storage and strong light irradiation to prevent active ingredient decomposition.
