About this ingredient
Sweet orange peel extract (Citrus Sinensis Peel Extract) is an extract from Citrus sinensis peel. Made by cold-pressing or solvent maceration. Active components: limonene (90-95% of essential oil), linalool, citral, flavonoids (hesperidin, naringenin), carotenoids. Where applied. Citrus-scented cosmetics, toners, scrubs, body products, shampoos, shower gels, antioxidant serums. Concentration 0.01-2%. In Spain – in L'Occitane Verbena, Roger & Gallet Orange, Heliocare 360 Antioxidant lines. Allergenicity. Contains limonene – an EU-labeled fragrance allergen. At leave-on >0.001% or rinse-off >0.01% – manufacturer must label "Limonene". On average orange peel extract contains 90-95% limonene plus linalool and citral – all three EU allergens. Mechanism. Flavonoids (hesperidin, naringenin) – antioxidants, neutralize free radicals and suppress MMP-1 (photoaging) in vitro. Limonene shows antibacterial action against Cutibacterium acnes. Carotenoids protect from UV and visible light. Evidence base. RCTs on topical orange peel extract are few. In vitro studies show antioxidant and mild antibacterial activity (Frassinetti 2011). Clinical efficacy at cosmetic concentrations is not confirmed. In formulas it mostly works as fragrance and a marketing "natural" component. Phototoxicity. Citrus oils (especially bergamot) contain furanocoumarins (bergapten, oxypeucedanin) – phototoxins. Orange has less than bergamot, but sun-induced pigmentation risk after peel-oil contact remains. Creams and serums with peel extract are better used in the evening. Safety. CIR confirmed safety at <2% in leave-on products. On damaged skin systemic absorption rises. Limonene-, linalool-, citral-allergic patients – avoid. Pregnancy and lactation – use with caution. Topically at cosmetic concentrations safe for the fetus, but phototoxic and contact-sensitization risks remain. Do not apply on damaged skin. Oral peel extract supplements in pregnancy are not recommended. Suitable for. Healthy adult skin without fragrance sensitivity. Atopics, eczema, fragrance-dermatitis patients – avoid. Before a sunny day, do not apply to exposed areas.
