Phenol 10%, 10 ml

Why Diluted Phenol Remains a Staple Laboratory Reagent

Phenol 10% in a compact 10 ml pack is chosen when precise dosing and small-scale testing matter more than bulk volume. This reagent belongs to the Chemical Raw Materials category, which brings together substances used in laboratory research, chemical synthesis and formulation development. The small packaging suits home laboratories, student projects, compounding pharmacies and trial batches before any move toward larger production volumes.

Globally, phenol is best known for its disinfecting and preserving properties. Diluted solutions are used to treat laboratory tools, glassware and work surfaces, as well as a fixative reagent for biological samples in microbiology and histology. In chemical analysis, phenol serves as a calibration standard, a reagent in qualitative reactions, and a component of buffer solutions. In pharmaceutical manufacturing, dilute phenol solutions are sometimes introduced as a preservative that limits microbial growth in finished preparations, with dosage strictly limited to a fraction of a percent of the total formula mass.

In dermatological research and cosmetic formulation, low-concentration phenol is studied as a component of exfoliating preparations, though handling it demands precise dosing and preliminary testing on small batches because the substance becomes aggressive once concentration limits are exceeded. This is exactly why a 10 ml pack is well suited for checking phenol compatibility with other formula components before scaling to production volumes.

When building blends, phenol pairs well with solvents and stabilizers, and formulators often reach for Glycerin 250 kg to soften the harshness of the solution and help retain moisture in the mix. In certain chemical reactions phenol interacts with salts such as Ammonium chloride, 25kg, which is used in laboratory synthesis of organic compounds. For powder and absorbent formulations that require even distribution of the active substance across a carrier surface, Talc, 25 kg is often added to ensure a stable, uniform application.

Phenol should be introduced at the final stage of solution preparation, at room temperature or below, since heating accelerates evaporation and reduces dosing accuracy. Store the solution in a tightly sealed dark glass container, in a cool place away from heat sources and open flame, kept separate from alkalis and oxidizers with which phenol reacts undesirably. When handling the concentrate, gloves and protective eyewear are essential, and dilution should be carried out gradually by adding the reagent into the solvent, never the reverse.
