Calcium Sulphate Dihydrate (Gypsum)

Fine powders can wet unevenly and form dry cores. Pre-disperse in a compatible phase or add slowly under good mixing rather than dumping the powder in at once.

It may create specks, drag or instability. A pre-dispersion or slurry is often more reliable, depending on the powder and formula.

Work gently, keep containers close to the work surface, use suitable PPE and local ventilation, and avoid pouring from unnecessary height.

Yes. Some powders absorb water or oil, while others change particle loading. Recheck flow, spread and pumpability after addition.

Natural origin, particle size and processing can produce small batch differences. Judge suitability against a finished-product specification.

Particulate powders usually reduce clarity unless they dissolve completely. If a clear finish is essential, choose a soluble or specifically designed ingredient.

Yes, if the formula does not provide enough suspension. Adjust rheology or design the product to be shaken before use if appropriate.

Dry raw materials have different microbial risks than water-based products, but once dispersed into water the finished formula needs an appropriate preservation strategy.

Keep them tightly closed, dry and protected from humidity, heat and contamination. Moisture pickup can cause caking and performance changes.
