The standard dilution ratio is approximately 1:10 — one part concentrate to 10 parts distilled water. This concentration is optimal for effective cleaning during tattoo sessions. Some artists prefer a higher concentration (1:7 or 1:8) for more intensive cleaning, while others prefer greater dilution (1:12) for sensitive skin.

The concentrated version offers three major advantages: concentration control, superior economy, and less storage space. A 500ml concentrated container produces up to 5 litres of soap, equivalent to five 1000ml Ready to Use containers. Experienced artists who know exactly the optimal concentration for their work style prefer the concentrated version.

Distilled or purified water is recommended for diluting Biotat Green Soap Concentrate. Tap water may contain chlorine, minerals, and impurities that could affect formula efficacy or irritate client skin. Distilled water ensures a pure and consistent dilution, maintaining all anaesthetic and antibacterial properties of eugenol.

The diluted soap maintains its efficacy for approximately 4-6 weeks after preparation, if stored in clean, tightly closed containers at room temperature. We recommend preparing quantities needed for 2-4 weeks to ensure maximum freshness. Label containers with the preparation date for efficient stock management.

Yes, when correctly diluted to the recommended ratio, efficacy is identical to the Ready to Use version. In fact, the concentrated version offers the flexibility to adjust concentration — higher for intensive cleaning or lower for sensitive skin. Experienced artists appreciate this additional control over the final product.

A 500ml concentrated container produces approximately 5 litres of diluted soap. On average, a tattoo session consumes 20-50ml of diluted soap. So 5 litres covers approximately 100-250 sessions. For a studio with 3 artists tattooing 5 days per week, a 500ml concentrated container can last approximately 2-3 months.

No, the concentrate should not be used undiluted — it would be too concentrated and could irritate the skin. When correctly diluted at the 1:10 ratio, the anaesthetic effect is equivalent to the Ready to Use version. Eugenol works at optimal concentrations, and overdosing does not increase efficacy but only the risk of irritation. Always follow the recommended dilution ratio.

We recommend food-grade plastic containers or professional spray bottles. 250-500ml spray bottles are the most practical for studio use, allowing direct application on skin or paper towels. Avoid metal containers that could react with the formula. Wash and disinfect containers before each reuse.

For equipment cleaning and disinfection, use specific products approved for medical surface disinfection. The concentrate can be used for cleaning the work area (table, arm rest) after the session but does not replace a professional disinfectant.
