As consumers are more educated about ingredients and the environmental impact that their skincare and makeup products have, it’s all the more important for companies to keep up with ingredient technology in order to cater to a savvy market.

Some ingredients in particular, have a bad rep amongst consumers for dehydrating skin, polluting the environment or being synthetic. One of the widely-debated ingredients is ethanol and the belief that it would dry out the skin and hair. In an earlier article, the omission of use of alcohol was also discussed when formulating for the expanding Halal beauty industry.

In Europe, the usage of alcohol in new fragrance launches has dropped from 78% in 2017 to 62% in 2021.

What are the alternatives for alcohol then?

Products like fragrances often rely on the use of alcohol to solubilize oil in water. An example would be the use of fragrances (which are oil-based) in water for various concentrations of perfume like eau fraiche, eau de toilette, and eau de parfum. Alcohol is usually the solubilizer in this case but there are alternative solubilizers that can be used based on the end product you are trying to create.

Here is a guide to synthetic and natural solubilizers for cosmetic formulating.

Solubilisant LRI

Solubilizers - Solubilisant LRI

Solubilisant LRI is a surfactant blend which has been designed as a substitute for alcohol in cosmetic and fragrance products. It’s compatible with preservatives and has excellent stability. As a cosmetic product, it minimizes stickiness, offers gentle cleansing properties while being mild enough for hypoallergenic formulations.

Only a low concentration of Solubilisant LRI is required to create a micro-emulsion when compared to its competitors. Various properties of Solubilisant LRI also make it ideal for use in different formulations—its clarity makes it suitable for fragrances unlike other solubilizers which can make the solution cloudy. It is also suitable for use in cleansers, especially those that require gentle care like the eye area.
