Professional Use Disclaimer

Fragrance loads vary by wax system. Results are starting-point guidance only — not guaranteed formulations.
IFRA compliance responsibility remains entirely with the user. Always verify fragrance oil IFRA category and usage limits with your supplier before production.
Testing is mandatory. Never produce a batch without fully tested and validated small-scale prototypes.
Wick selection, wax type, vessel diameter and fragrance oil chemistry all affect candle performance. Multiple test pours are non-negotiable to ensure safe, compliant and consistent results.

Water to Wax Conversion

Fill your vessel with water and weigh it to determine how much wax it holds. Optional — skip if you already know your vessel fill weight.

Volume of Water (grams) Fill vessel with water, weigh in grams

Wax Density Factor Default 0.85 for most coconut apricot wax blends

Calculated Vessel Fill (grams) Auto-filled below in Section 2 — override if needed

—

Vessel Fill = 100% of candle weight. Wax + Fragrance Oil always equals the vessel fill weight.

Vessel Fill Weight (grams) Auto-filled from Section 1 or enter manually

Fragrance Oil % Recommended 6%–10%. Max 12%. Enter as number (e.g. 9 for 9%)

Wax per Candle — grams

Fragrance Oil per Candle — grams

Vessel Fill (100%) — grams

Always Remember

These calculations are a starting point. Real-world performance depends on your specific wax, fragrance oil, vessel, wick and pour temperature.
Coconut apricot wax blends typically perform best at 6%–10% fragrance load. Testing at your specific load is always required.
Record every test pour: fragrance load, cure time, cold throw, hot throw, burn pool, mushrooming, soot. Your data is your quality system.
IFRA compliance is your legal responsibility as the manufacturer. This tool does not assess IFRA compliance.
Wick size, wick positioning and vessel diameter interact with fragrance load. A change in FO % may require re-wicking.
