Feuillesol - Solubilizer (Clear)

Natural Solubilizer (Colorless - Odorless)

INCI Name: caprylyl/capryl glycosides, aqua, sodium cocoyl, glutamate, polyglyceryl-10 myristate,
glyceryl, caprylate, citric acid

Description: To facilitate the addition of essential oil blends to water-based products, this powerful solubilizer is made of 100% plant origin for use in natural products. Consisting of naturally derived surfactants and wetting agents, Feuillesol has shown excellent performance for solubilisation.

Use: The approximate ratio of Feuillesol to essential oils is slightly more than 1 part up to 5
parts Feuillesol to 1 part essential oils. Experimentation is required as the optimal ratio will
vary depending on the types of oils to be solubilized and the base product. Relative clarity of the
product will generally improve the higher the percentage of solubilizer to oils.

Feuillesol should be mixed directly with essential oils only prior to adding to the water-
based product. The resulting (Mixture) should then be added. Creating the essential oil and
Feuillesol (Mixture) 24 hours in advance may increase solubility.


Feuillesol works best at pH values from 4.5 to 7.5. Electrolytes (e.g. NaCl) and ethanol can
reduce the dosage of Feuillesol necessary for transparent solubilization. Ethanol should be
added at the end to the aqueous solubilisate and not during the solubilization since this may lead to turbidity. Cationic compounds can lead to irreversible turbidity.

PEG- and PPG-free
Created from sustainable resources.
Acceptable in certified products including shower gel, shampoo, toner, and other water-based products.
This ingredient is biodegradable, not tested on animals, non-GMO, and gluten free.

Compared to other PEG-free natural solubilizers, Feuillesol demonstrates a comparable performance to PEG-40 hydrogenated castor oil, the industry standard.
