Why is Orange Essential Oil Used in Skincare?

Posted by Dr. Natasha Ryz on

Orange essential oil is extracted from the peels of the orange Citrus sinensis

Orange essential oil is widely used in skincare products for its fresh, pleasant citrus aroma. Orange essential oil and its major component limonene also have cleansing activity, antioxidant activity and are permeation enhancers. 

Orange essential oil is composed of ~95% D-limonene and other minor compounds, including beta-myrcene, linalool, alpha-pinene, sabinene and others.

Why is orange essential oil used in skincare?

Orange essential oil is used in skincare for its aroma, cleansing activity, antioxidant activity and as a permeation enhancer. 

1. Aroma 

Orange essential oil smells delicately sweet and tangy with the aroma of fresh cut juicy oranges.

As orange essential oil ages and oxidizes, the aroma fades. So fresher orange essential oil smells the best. You can almost smell the sparkles in very fresh orange essential oil!

Orange essential oil is in the citrus aroma family and is considered a top or a head note in perfumery. 

Orange essential oil smells great on its own, but it also blends well with other aromas, especially other citrus essential oils like bergamot, grapefruit and neroli blossom. It can add sweetness to formulas and help smooth out harsh aromas.

Orange essential oil can also be used as a masking agent, and cover-up unpleasant odors.

The aroma of orange essential oil is very calming and smelling orange essential oils may reduce anxiety and improve mood (Goes et al, 2012; Jafarzadeh et al, 2013; Lehrner et al, 2000; Lehrner et al, 2005; Rashidi-Fakari et al, 2015).

2. Cleansing activity

Orange essential oil is composed of ~95% D-limonene, which is used as a cleanser and a degreaser. 

Orange essential oil and limonene are gentle, yet powerful cleaners that are reputed to effectively remove grease, tar, oil, soot, grime and soils.

Limonene is a cleanser and a degreaser. Orange essential oil and limonene are used as solvents in water-free hand-cleansers at a concentration of about 10% (Karlberg et al, 1997).

Its mildness has made orange essential oil and limonene popular ingredients in water-free hand soaps, as they not only cleanse, but also leave hands smelling fresh. 

3. Antioxidant activity

Antioxidants protect your skin by preventing free radical damage.

Free radicals are unstable molecules or atoms that can damage skin cells.

Free radicals are generated from normal aging, and by daily environmental damage - such as UV radiation from the sun and air pollution. Free radicals cause destruction to your cells and tissues, and accelerate skin aging (Masaki et al, 2010).

Antioxidants protect your skin by neutralizing unstable free radicals.

Orange essential oil has antioxidant activity (González-Mas et al, 2019; Lin et al, 2021; Li et al, 2022),

Limonene also has antioxidant activity (Anandakumar et al, 2021).

Recently, limonene has been shown to have a protective effect in skin cells by activating a cellular antioxidant defense system (Kumar et al, 2022).

Orange essential oil and limonene may increase product shelf life (Bora et al, 2020; Xu et al, 2021). Limonene has been shown to inhibit lipid oxidation and is being investigated to extend shelf-life in food products (reviewed by Bora et al, 2020).

4. Permeation enhancer

The delivery of active ingredients into the skin is a challenge. 

Permeation enhancers help the skin absorb active ingredients.

More specifically, permeation enhancers are substances that improve the absorption of drugs or active ingredients through the skin by increasing skin permeability. 

Orange essential oil is made of ~95% D-limonene, which is a permeation enhancer (Mendanha et al, 2017) and can boost absorption of nutrients and active ingredients (Valgimigli et al, 2012).

Is orange essential oil safe?

Citrus essential oils are non-toxic, non-mutagenic, and non-carcinogenic (Tisserand et al, 2014; Dosoky 2018).

Orange essential oil has GRAS (generally recognized as safe) status. However, there is a possible skin sensitization issue if old or oxidized oil is used (Tisserand et al, 2014).

Expressed orange oil was neither irritating nor sensitizing to 25 volunteers when tested at 8 and 100% (Opdyke et al, 1974), whereas it caused sensitivity to 0.13% of total dermatitis patients when tested at 2% (Rudzki et al, 1976).

Orange essential oil is composed of ~95% D-limonene.

Pure limonene is safe for most people to use, when it is properly diluted. 

Old or oxidized limonene may cause irritation in people with dermatitis or other skin issues. 

Always choose fresh products and avoid the use of old or expired products that contain limonene.

Orange essential oil is widely used in skincare products for its fresh, pleasant citrus aroma.

Orange essential oil and limonene have cleansing activity and are common ingredients in cleansers, especially hand cleansers.

Orange essential oil and limonene also have antioxidant activity and protect skin against oxidative damage. Orange essential oil and limonene may also extend product shelf life of skincare products.

Orange essential oil and limonene are permeation enhancers and may boost absorption of active ingredients into the skin, including vitamins.

Orange essential oil and limonene are safe for most people to use in skincare.
