Sodium butylparaben is a water-soluble paraben-based preservative with specific solubility and pH-dependent stability characteristics. In terms of solubility performance, the raw material is freely soluble in water, slightly soluble in ethanol, and practically insoluble in all grease and oily mediums. Its chemical stability is highly affected by formula pH values. When applied in acidic environments with pH below 7, the product will undergo hydrolysis reaction, restoring to oil-soluble butylparaben. The regenerated parent substance is insoluble in aqueous systems and prone to precipitation. The optimal antibacterial working range of the ingredient is pH 4 to pH 7 (acidic to neutral conditions), while its antimicrobial efficacy will gradually decrease in alkaline formula environments. For daily storage, the product needs sealed packaging and placement in cool, dry and ventilated environments, with isolation from strong acidic substances and strong oxidizing agents to prevent quality changes and moisture absorption.
Key Advantages
Despite qualified antibacterial capacity, restricted toxicological properties and industry regulations greatly limit its commercial application scenarios.
As a modified salt-form paraben derivative, sodium butylparaben solves the water-insoluble defect of original butylparaben, enabling direct application in aqueous formula systems.
It delivers stable and effective bacteriostatic and antifungal performance within the optimal pH range of 4–7, covering common microorganisms contaminating cosmetic and pharmaceutical products.
With single and pure ingredient properties, it features simple formula compatibility rules.
Strict standardized storage operations can effectively avoid raw material hydrolysis, precipitation and failure.

Applications
Theoretically, sodium butylparaben can serve as a professional water-soluble antibacterial preservative for fine chemical products. It is applicable to cosmetic formulas, daily personal care products and pharmaceutical preparations for microbial inhibition and shelf-life extension. However, due to relevant toxicological risks and updated global industry regulatory restrictions, the practical commercial application of this ingredient is extremely rare in modern production and formula development, and it is hardly adopted in mainstream mass-production formulas.
Packaging & Storage
Packaging ：25kg per paper drum ,o r as per customer's requirements.
To maintain intact chemical properties and avoid ingredient hydrolysis, the product must be stored in a fully sealed state. The storage environment requires cool temperature, low humidity and good ventilation. Operators must prevent raw material moisture absorption and agglomeration during storage and handling. In addition, mixed storage and contact with strong acid chemicals and strong oxidants are strictly prohibited to avoid chemical reactions leading to product failure and quality deterioration.
