Give every version a number
Use a project code, version and date. When the formulation changes, create a new record and explain the change and its purpose. A successful trial should be reproducible.
Record the base formula
- Raw-material trade name, INCI, supplier and batch.
- Function, phase and mass percentage.
- Target sample size and actual weighed quantities.
- Order of addition, temperature, time and mixing conditions.
- Measured pH and viscosity where applicable, plus appearance.
Percentages must total 100
In a 100 g sample, one mass percent equals 1 g. In a 250 g sample, it equals 2.5 g. Check the total after every change. Adjusting water to 100% does not mean the remaining ingredients can be changed arbitrarily.
Change one parameter at a time
Changing the emulsifier, oil and thickener together makes it difficult to identify what improved or damaged the sample. Compare versions under the same conditions and record results using consistent criteria.
Documentation accompanies testing
An attractive first sample is a starting point. Stability, microbiological quality, packaging and safety programmes depend on the product. PIBU LAB's base-formula series uses this structure to explain formulation decisions step by step.
