An overview of pomegranate extract.
The name "Punica granatum" is used to refer to both the tree and the fruit of the pomegranate. This is a tree that grows between 2 to 5 metres high, belonging to the Punicaceae family. Originating from Central Asia, the cultivation of the pomegranate has spread to several countries such as Tunisia, Morocco, Egypt, and even America. As a mythical fruit, numerous benefits are attributed to the pomegranate. In Egyptian mythology, it is considered a symbol of fertility. Its use also extends to medicine, and recently, to skincare and haircare.
To harness all its benefits, the pomegranate is utilised in the form of an extract. This plant-based active ingredient is obtained following a process described below.
The stages of production for pomegranate extract.
The pomegranate or Punica granatum is rich in antioxidants, including tannins, soluble polyphenols, and anthocyanins. This fruit undergoes various stages to maximise the preservation of these molecules before being incorporated into skincare and/or haircare products.
Firstly, the fruits are harvested, typically in the Maghreb region.
The barks are removed and ground down.
The resulting mixture is left to macerate in a 95° ethanol solution. This is referred to as extraction carried out using an alcoholic solvent.
The juice obtained is filtered and a desolventisation process is carried out (a procedure in which the solvent mixed with the extraction meal is removed). We obtain a crude pomegranate extract (native extract).
In order for this extract to retain its molecules and functions until its incorporation into a skincare product, it is mixed with glycerine and demineralised water.
