How to formulate stable personal care products
Using particle size, zeta potential and rheological data
As a consumer you may remember using that sunscreen that came out of the bottle like water, or a body cream that was too thick and felt lumpy? Then you know, even the best personal care products can be a disappointment if their storage stability isn’t good.
As a formulator, you may be the person responsible for preventing such stability issues, often by making multiple formulations and spending many days and hours performing stability trials and measurements to assess which formulation candidates to take forward.
Formulating to avoid these pitfalls and reduce stability testing is much easier when you can understand, characterize and predict stability issues. This brief article highlights key tests that you can run and how to interpret the data with “Getting Personal with Characterization: Using particle size, zeta potential and rheological data to formulate stable personal care products”.
