- The dosage of EasyTens® S2 depends on the perfume being introduced into a formulation and should be evaluated accordingly.
- It is advised to premix the perfume with EasyTens® S2 before adding water.
- The right dosage can be found by mixing the desired amount of perfume with EasyTens® S2 starting with a ratio of 1:1 and subsequent addition of water.
- If the solution turns cloudy the concentration of solubiliser needs to be increased until a transparent solution is obtained.
- Additionally the required concentration of EasyTens® S2 for a selection of perfumes and essential oils is provided in figure 1 and can be used as a formulation guideline.
Oil components + EasyTens® solubiliser → Solubiliser and oil blend + Watery components → Finished formulation

Technical Details & Test Data
- Performance
Figure 1: Required concentration of EasyTens® S2 for a selection of various perfumes and essential oils.
In most cases EasyTens® S2 performs better than EasyTens® S2 Pure and is easier to handle due to its lower viscosity. However in formulations containing cationic compounds it is recommended to use EasyTens® S2 Pure since the anionic component of EasyTens® S2 could lead to undesirable effects. When using EasyTens® S2 Pure it is recommended to heat it to approximately 40°C prior to the perfume addition to facilitate the mixing process.
EasyTens® S2 and EasyTens® S2 Pure show comparable performance to market standard PEG-solubilisers which is shown in figure 2 for some example perfumes and essential oils.
Figure 2: Performance of EasyTens® S2 and EasyTens® S2 Pure in comparison to polysorbat 20 and PEG-40 hydrogenated castor oil.
EasyTens® S2 even outperforms other naturally derived solubilisers for many perfumes and essential oils as can be seen in figure 3.

- Influence on the Viscosity of Formulations
Unlike market standard PEG-solubilisers which can drastically lower the viscosity of a basic surfactant blend EasyTens® S2 and EasyTens® S2 Pure have a low impact on the viscosity in concentrations of up to 1%. At higher concentrations the viscosity starts decreasing which is shown in figure 4 for EasyTens® S2.
