Does a Chelating Shampoo Suit Your Water? Run a Two-Water Sample Test
Compare a chelating shampoo in two characterized waters before selecting a formula for hard-water salon retail or a small private-label launch.
Compare the candidate and your benchmark under both target-market water and a reference water. This helps distinguish a water-dependent complaint from a formula that simply feels too cleansing under all conditions.
Why a water test belongs in the brief
The in-cosmetics Asia technical program includes ingredient and formulation sessions during its Bangkok show. That is a sourcing signal, not proof of demand for a particular shampoo. Use the technical discussion to ask what mineral-removal data actually exists for the proposed finished formula.
Set up four comparisons
Use comparable hair swatches: candidate in target water, benchmark in target water, candidate in reference water and benchmark in reference water. Record hardness where measured, temperature, dose, contact time and rinse volume. Use separate swatches or plan a crossover that accounts for prior treatment; do not let the first wash change the baseline for the next.
Separate practical feel from mineral removal
Compare rinse time, wet combing and dry feel using the same procedure. Visible foam can be recorded but should not decide which sample removes mineral deposits. If a label will name specific minerals or quantify reduction, ask for a suitable analytical method, comparator and sample conditions.
Decide what to buy
If the candidate improves the target-water experience without unacceptable dry feel, review a filled stock-pack sample. If both products feel rough in both waters, revisit the cleansing and conditioning brief. Selected mature formulas with compatible stock packaging may start at 100 units; packaging changes are reviewed from 500 subject to process.
Frequently asked questions
Does more foam prove chelation?
No. Foam and mineral removal are different observations.
Can a visual result substantiate a percentage?
No. Request an appropriate quantitative study.
Should the test use dyed swatches?
Include them if color-treated customers are part of the intended audience.
