01 / FORMULA

A formula worth
coming back to.

Write the stock as it appears on the bottle, then record every amount by mass. Keep a version so the next experiment has a clear starting point.

TOTAL
Keep two numbers separate. Neat material = stock mass × stock strength ÷ 100. For example, 2.5 g of a 10% stock contains 0.25 g neat material and 2.25 g stock solvent. This is arithmetic, not a perfume recipe.
Stock solvents / lot numbers / change from last version

A calculation does not establish solubility, stability, skin suitability or compliance. Follow the documentation for your exact materials and intended application.

02 / BATCH & COST

Make the batch.
Keep the record.

Plan the amounts, record what actually happened, and cost the bottles you can fill. Use grams for mass and one currency throughout.

Evaluation / follow-up date
Starting mass = target recovered mass ÷ (1 − loss % ÷ 100). Concentrate = starting mass × dose % ÷ 100. Added carrier = starting mass − concentrate. Bottle volume does not equal fill mass.

What did it cost?

Concentrate + added carrier
Packaging + labels
Labour + other batch costs
Total / complete bottle count

What is the price?

Cost per complete bottle
Target gross margin (%)
Price = cost ÷ (1 − margin ÷ 100)
Comparison markup (%) / price

Margin = profit ÷ price. Markup = profit ÷ cost. At a 12-unit cost, a 60% margin gives a 30-unit price; a 60% markup gives 19.20. Include taxes and selling costs only as appropriate to your own assumptions.

03 / BLOTTER STUDY

Let the scent
tell its story.

Follow the same strip through five observations. Choose your own intervals and record the elapsed time. Describe what you perceive before deciding what to change.

One question for the next trial.

Keep the conditions consistent. Changing one variable makes the comparison easier to interpret.
