Covasilic 15 liquid thickener for oil gels

Covasilic 15 is a modern liquid thickener designed to create transparent oil gels, oil based serums, massage preparations and premium sensory textures. It transforms a wide range of vegetable, synthetic and mineral oils into a stable gel structure without heating. The ingredient improves spreadability, enhances glide and delivers a smooth satin finish highly valued in cosmetic formulations.

Purpose

Covasilic 15 is used to thicken oils without affecting transparency or colour. It forms a uniform gel matrix capable of holding active ingredients, aromatic components and oil soluble extracts. This makes it suitable for oil serums, gel oils, cuticle products, spa preparations, perfumed oils and decorative cosmetic textures. The gel structure helps retain aroma, improves stability and prevents separation.

Properties

Covasilic 15 creates a dense yet flexible gel texture that feels soft and elegant on the skin. It reduces greasiness, enhances slip and improves the overall sensory profile of the formula. The thickener is compatible with a wide range of esters, emollients, essential oils and oil soluble botanical extracts. It does not whiten, does not cloud the product and allows the creation of clear gel oils with stable viscosity.

Application

It is added into the oil phase and mixed until a uniform gel structure forms. Light oils typically require 5–8 percent. Heavier oils or esters may need 10–15 percent. Covasilic 15 stabilises fragrances and active ingredients, making it ideal for both skincare and decorative beauty products.
