Hydroalcoholic extracts

The solvents used to extract the active ingredients are: water, propylene glycol, glycerine and alcohol.

Solvents are used according to the type of active ingredient required, and whether a particular substrate is to be preferred or eliminated.

Historically, the most common in cosmetics are hydroglycolic extracts, whose solvents are water and a glycol (either propylene glycol or butylene glycol). The ratio of water to glycol is 50:50.

Today, there is a growing interest in extracts whose solvent is glycerine, with a water:glycerine ratio of 50:50, with or without preservatives.

Extracts can be preserved with various preservatives.

We offer an effective cocktail of preservatives as standard: citric acid, sodium benzoate and potassium sorbate at 0.2% each.

We also work with other preservatives at our customers' request.
