Optimization of tooth paste foaming behaviour using foam tests

The foam volume of tooth paste is one of the few quality characteristics being recognisable for the user and has therefore a strong influence on the consumer's decision to buy the tooth paste again or not.
Investigations of tooth paste foam have shown that the subjective feeling of the cleaning effect of tooth pastes with a high foam volume is bigger than of those with a low foam volume. Beyond this, the tooth paste foam reaches parts in the oral cavity where a conventional tooth brush would not get access to. As a result, the radius of operation of the tooth paste foam increases with foam volume.

Besides the foam generation, the foaming behaviour and the foam stability play an important role. A reproducible measurement of the parameters foam development and foam decay is neccessary to prevent subjective influences.

The SITA FoamTester and its patented Rotor-Foam-Method measure all data automatically, whereby subjective influences caused by the user are excluded.

Optimization of shampoo foaming behaviour using foam tests

The foam volume of shampoos is one of the few quality characteristics being recognisable for the user. If a shampoo develops a lot of foam, the user assumes a high cleaning potential and an intensive caring effect. Further foam attributes, e.g. the foam development as well as the foam stability, have an influence on the customers' quality feeling. In addition, intensive foaming increases the dispersal of the shampoo.
