What is lemongrass hydrosol?
Also known as "Indian verbena", Java citronella belongs to the Poaceae family. This plant is sterile, without flowering. As soon as the leaves are crushed, a distinctly lemony fragrance is released.
Prior to its introduction in Europe in the 19th century, the British and Dutch engaged in extensive maritime trade of this plant, as its fragrance was highly sought after by the nobility. In exotic countries, Java citronella is still used today as a mosquito repellent; it is therefore planted around dwellings.
From its long, narrow leaves with sharp edges, essential oil and hydrosol are extracted through steam distillation. This involves carrying the aromatic molecules or volatile constituents (the essential oil) with the steam, then cooling this steam which condenses in the essencier to produce the hydrosol. The latter is primarily composed ofgeraniol, citronellal, citral, geranial, neral and alpha-thujene.
Unlike essential oil, there are no contraindications for the external use of lemongrass hydrosol. It can be used by pregnant and/or breastfeeding women as well as children. Sensitive to oxidation, it should be stored for 6 months after opening, preferably in the refrigerator. If you notice a change in appearance or smell, stop using your hydrosol.
The cosmetic virtues of Java lemongrass hydrosol.
When applied topically, Java citronella hydrosol helps to reduce skin imperfections; it is recommended for oily skin as well as acne-prone skin. Indeed, it has a purifying and astringent effect. Due to its slightly acidic pH, it visibly tightens the pores. It regulates sebum production and mattifies oily skin that tends to shine. Moreover, its anti-bacterial activity helps to limit the proliferation of microorganisms involved in acne such as P. acnes. Because of these virtues, this hydrosol is combined with glycolic acid in our exfoliating tonic. Highly concentrated, this lotion helps to tighten the pores and remove dead cells for smoother and more unified skin. The deep-cleansing action of glycolic acid effectively eliminates blackheads.
Other potential uses : The Java citronella hydrosol reduces unpleasant body odours. It can therefore be used as a gentle and natural deodorant. Regarding its application to hair, its content of monoterpenols allows it to soften the hair and revive its shine. As a sebum regulator, it also fights against oily hair and potential dandruff.
