Nothing can take the place of this when making stable formula. When your formulation gets contaminated, yeast mold and bacteria will degrade your ingredients and render it worthless.
Use 70% Isopropyl alcohol (rubbing alcohol) to sanitize your beakers and other tools before you start.
After washing your beakers, ensure you spray it with Isopropyl alcohol and allow it to dry naturally.
Use enough emulsifier, a thickener and a gum
This applies only if you are making lotion, body cream and other skincare products that require water in oil and oil in water emulsion process.
For instance if your emulsifier manufacturer recommends 6% and you used 3% to prevent soaping effect, your lotion will not be stable. Stability is very important in challenge test as your product will be subjected to different temperature settings.
