White Grapefruit Essential Oil, 10 ml

White grapefruit essential oil gives products a fresh, clean citrus scent and is particularly suited to products intended to refresh and help skin or hair rid itself of excess sebum: shower gels, shampoos, tonics for oilier skin, bath salts and candles. It is obtained by cold pressing from the peel of grapefruit fruits, without the use of heat or solvents, which is why it retains the character of fresh peel (Citrus Paradisi Peel Oil).

In a formulation it serves two roles at once. It is primarily a fragrance ingredient with a light, energetic tone that blends well with other citruses, mint, rosemary or herbal oils. At the same time, the manufacturer attributes astringent and cleansing properties to it, which is why it is used in care products for oily skin and scalp.

What to expect from the oil

• Fragrance – fresh, clean grapefruit scent, a typical citrus top note that opens the product and develops quickly.
• Oily skin – according to the manufacturer's data, the oil has an astringent and cleansing effect, helping to balance oily skin and reduce the appearance of imperfections. For this reason it is used in cleansing gels, tonics and masks.
• Scalp – the manufacturer states that it helps remove excess sebum and styling product residue from the scalp, which is why it is added to shampoos and rinse-out conditioners.
• Cooling and refreshing sensation – according to manufacturer data, it has a refreshing and cooling effect on the skin, which is utilised in after-sun products and bath preparations.
• Origin – according to the manufacturer, the oil is vegan and not tested on animals; it comes from North American fruits.

Use in formulation

The essential oil is not water-soluble. In anhydrous products (oil serums, massage blends, balms, bath salts with a carrier oil) it is simply blended into the oil phase. In emulsions it is added to the oil phase or at the very end into the cooled emulsion. For water-based products such as tonics, refreshing sprays or shower gels with a low surfactant content, a solubiliser is required (for example Polysorbate 80 or PEG-40 Hydrogenated Castor Oil), otherwise the oil will separate on the surface. In shampoos and shower gels with a sufficient amount of surfactants it will usually disperse even without one, but it is advisable to check clarity on a test batch.

Dosage depends on the type of product. For products that come into contact with skin, IFRA limits apply for the individual product categories; the categories to which this oil belongs are listed in the product parameters. Leave-on products (creams, body oils, deodorants) generally have stricter limits than rinse-off products (soaps, shampoos, shower gels). Separate, strictest categories apply for products intended for children and for lip products.

The colour of the oil ranges from colourless to dark yellow depending on the batch. In white creams and clear tonics it will not show at typical dosages; at a higher proportion in a clear bottle the product may turn slightly yellow.

Suitable for products such as

• Rinse-off cosmetics – shower gels, liquid and solid soaps, shampoos and conditioners, where both the fresh fragrance and the cleansing character of the oil come into play.
• Oily skin care – cleansing gels, tonics (with a solubiliser) and masks.
• Body products – massage oils, body oils, bath salts, after-sun products; always within IFRA limits for the given category.
• Room fragrances and candles – aroma lamps, diffusers, container candles and scented waxes, where grapefruit complements other citruses and herbs well.

What is worth knowing

Citrus oils are among the top notes that evaporate from a finished product more quickly than woody, resinous or floral oils. If the fragrance is to last longer, combining it with heavier ingredients (cedarwood, patchouli, benzoin) or with a fixative works well. With candles and scented waxes it is worth testing the intensity on a small sample, as a light citrus note may perform more weakly in hot wax than the scent from the bottle suggests.

Cold-pressed citrus oils are prone to oxidation. In a finished product with an oil phase, adding an antioxidant such as vitamin E helps slow down fragrance change. When choosing packaging, bear in mind that concentrated essential oils can attack certain plastics; glass is more suitable for storing blends with a higher oil content.

The oil itself does not require preservation, but every water-based product to which it is added must have its own preservation system. The essential oil does not replace it.
