Symbio Solv Clear Plus, Solubilizer, 50 ml

Symbio solv clear plus is a solubiliser of plant and biotechnological origin that incorporates essential and fragrance oils into aqueous products while keeping them clear. It is suitable wherever a small amount of oil needs to be dispersed in water without an emulsifier and without cloudiness: in tonics, facial waters, refreshing sprays, spray deodorants or bath salts. It is worked with cold, dosed at low percentages and carries COSMOS Approved certification.

What it is suitable for

• Clear aqueous products with fragrance – an essential or fragrance oil is dispersed in water via the solubiliser into fine droplets. The solution remains transparent and does not separate.
• Incorporating oil-based components – a small amount of an oil-based component can be introduced into a tonic or light serum without forming an emulsion.
• Cold processing – the recommended temperature is up to 40 °C, so volatile components of the fragrance composition are not exposed to heat.
• Broad compatibility – it is compatible with non-ionic, anionic and amphoteric surfactants and with acidic to neutral pH. It can therefore also be used in shower gels and shampoos.
• Replacement for ethoxylated solubilisers – for formulations that should be PEG-free and contain ingredients of natural origin.

Use in formulation

The recommended dosage is 0.5 – 5 % of the total weight of the formulation. The required amount depends on how much oil and of what type you wish to solubilise. We recommend setting the ratio of solubiliser to oil on a small sample first, and then scaling up to the full batch.

The procedure is the same as with other solubilisers. First, the solubiliser is thoroughly mixed with the essential oil or fragrance composition to form a uniform blend. Only this premix is then added to the water with continuous stirring.

It is added to the water phase, during the cooling phase or additionally into the finished product, always at a temperature below 40 °C. The recommended pH range of the formulation is 4.5 – 6.5. Outside this range, verify stability on a sample.

Suitable for products such as

• facial tonics and facial waters with essential oils
• refreshing face and body sprays, spray deodorants
• hair sprays and scalp waters
• interior sprays and aqueous blends for diffusers
• bath salts and bath bombs, so that the oil disperses in water after dissolving and does not remain floating on the surface
• shower gels, shampoos, bath foams and liquid soaps with added fragrance

Good to know

• Preservation – the solubiliser does not replace a preservative. An aqueous product with solubilised oil requires a preservation system like any other aqueous product.
• Colour – the raw material is yellow. At higher doses it may slightly affect the shade of a clear product; verify on a sample.
• Cationic components – compatibility is stated with non-ionic, anionic and amphoteric surfactants. Before use in conditioners with cationic components, verify in the finished formulation.
• Creams and emulsions – the solubiliser handles a small amount of oil in a clear solution. For emulsions with a higher proportion of oil phase, an emulsifier is required.
