Solubilizer
Description
Natural Solubilizer – PEG-free, aqueous solutions with fragrance oils and lipophilic active ingredients.
The solubilizer features excellent solubilization performance, designed to solubilize essential oils, fragrances, and various lipophilic ingredients in water-based preparations.
It is a 100% natural-origin blend created as an alternative to traditional ethoxylated solubilizers (such as PEG-40 Hydrogenated Castor Oil or Polysorbate). Its formula combines an alkyl glucoside with a glutamate and a glycerin ester, achieving an effective system at low concentrations due to its low critical micelle concentration (CMC).
It is suitable for both clear aqueous formulas and surfactant systems, performing well in both the presence and absence of ethanol. It provides a pleasant sensory feel without a sticky effect and additionally contributes to foam quality in cleansing products.
Ingredients (INCI): Caprylyl/Capryl Glucoside; Aqua; Sodium Cocoyl Glutamate; Glyceryl Caprylate; Citric Acid; Polyglyceryl-6 Oleate; Sodium Surfactin

- Wet wipe solutions.
- Shower gels and body/hair cleansing products.
- Foam-type formulations.
Formulation Guide
- Working Procedure: premix the solubilizer with the oil at room temperature; then add the water, aqueous phase, or surfactant base under continuous stirring; adjust pH to 4.5-6.5 if necessary; if the formula contains ethanol, add it at the end in small portions.
- In Aqueous Solutions: indicative oil:solubilizer ratio dosage between 1:3 - 1:5, up to a maximum of 5% in the final formula. In practice, start with a 1:3 ratio (one part oil, three parts solubilizer); if the solution remains cloudy, increase the solubilizer proportion and restart the process from the premixing step.
- In Surfactant Formulations: indicative dosage for surfactant-based products, 0.5-1.5%. The solubilizer may reduce formula viscosity; viscosity adjustment should be made at the end of the formulation process.
- Compatible with: natural fragrances, essential oils, conventional fragrance oils, lipophilic active ingredients, synthetic esters, ethanol (max. 10%), non-ionic conditioning agents.
- Incompatible with: vegetable oils and cationic compounds.
- Avoid overdosing the solubilizer to prevent excessive and unnecessary foaming.
Usage Safety and Storage
- Profile: Ingredient with good skin tolerance.
- Precautions: External cosmetic use
- Storage: Store in a cool, dry place, protected from sunlight
