Even the most demanding customers will remain loyal to a brand if they enjoy their experience with a particular product. This is especially true for the cosmetics industry. Foam often plays the main role because it conveys pleasant sensations – provided that it shows exactly the right properties for each care application.
Reliable scientific methods are the key to targeted product design – and when it comes to personal care products, even soft foam needs to be evaluated with solid key figures. Nevertheless, many manufacturers still use homemade test procedures and subjective assessments for foam evaluations. This makes it difficult to give foam specific features and to define objective criteria for quality. Fortunately, there are efficient and easy-to-use methods for expressing the most important aspects of foam – volume, stability, moisture, and bubble size – in scientifically substantiated values.
