FREQUENTLY ASKED QUESTIONS

No. Potassium Alum is an aluminium-containing salt. A natural-mineral description does not change its chemical composition.

No. They are different salts. Confirm the required identity and specifications rather than treating all products called alum as identical.

The solution may be too concentrated for the later storage temperature, or water may have evaporated. Establish a concentration that remains stable in the complete formula under expected storage conditions.

Do not assume compatibility. Their interaction can change pH and produce insoluble material, affecting appearance, dispensing and performance.

Alum adds electrolytes that can affect some polymer thickeners. Reassess the polymer grade, pH and salt tolerance rather than adding more thickener blindly.

Do not assume so. The complete formula, including added water and botanicals, needs an appropriate microbiological safety assessment.

No. Stinging is not an efficacy test. Reassess the formula and exposure, particularly on recently shaved or irritated skin; persistent discomfort is a reason to stop use.

Check corrosion and closure compatibility with the actual formula. The liquid and its pH can interact with exposed metals; appearance alone does not establish a suitable pack.

Do not make that promise. Astringency or deodorant use does not establish a validated pigmentation treatment.

Separate odour control, skin feel and sweat reduction in the test brief. Do not assume similar consumer descriptions mean the products deliver the same measured functions.
