Nut Derived Oils & Other Proteins

Where brands use purified nut oils, SCA will endorse products with the Allergy Certified logo that do not contain the proteins responsible for allergies to nut oils and other derivatives. Cosmetic nut oils include: Almond, Shea, Argan, Peanut (is actually a legume: arachis hypogaea) and Macadamia.- List of Nuts. (Coconut & Nutmeg are not nuts). Cosmetic proteins include: milk, silk, collagen, keratin and elastin.


The primary treatment of allergies, is to avoid the trigger. However, cosmetic ingredients are highly processed, so do they pose a risk to allergy sufferers? The best advise is to avoid known allergens and irritants, always read the product label ingredients, and if your not sure then do not use it. Always patch test a new product before using it, and always follow the advice from your GP or health practitioner.

  • "Studies have found that contact allergic reactions can occur due to exposure to allergens in cosmetics. But these reactions only occur if the relevant proteins are intact, so in general, the more processed and refined the cosmetic, the smaller the likelihood of a reaction." - Nut Allergies & Shampoo

  • "Currently, various wheat-derived substances, including multiple forms of wheat protein (such as gluten), are processed through hydrolysis, as are other protein hydrolysates such as collagen, keratin, elastin, milk, almond, and silk, and used in myriad skin and hair products, such as soaps, bath gels, creams, and hair repair formulas.3-6 In particular, wheat – like oat – is incorporated into personal care products for the moisturizing benefits it confers.1 The positive and negative effects of the incorporation of wheat into skin care as well as the cutaneous effects of wheat supplementation are the focus of this column." - Dermatology News: Wheat in skincare by Leslie S.

  • "More confusing, someone with a nut allergy won’t necessarily be allergic to a nut oil in a product. It’s the protein in the nut that causes an allergic response, and some manufacturers say they remove the protein from the oil. This can involve chemicals or heat — an important distinction for a consumer interested in a natural product." - Alexandra Zissu, NY Times, Allergies Can Be Natural Too


SCIENCE DIRECT: "Protein families involved in tree nut allergy. The majority of proteins involved in tree nut allergy belong to protein families of 2S albumins, vicilins, legumins, and nsLTPs. Bet v 1-homologues and profilins are involved in pollen associated tree nut allergy (Fig. 1). Also, oleosins and thaumatin-like proteins were shown to be important allergens. An overview of the already identified allergens is given in Table 1, Table 2, Table 3." -
