Protein Analysis in Cosmetics

Currently, the use of protein-rich substances in formulations is believed to have beneficial effects. Proteins are useful ingredients that can create a suitable environment for healthy skin and hair because of their ability to bind water with the horny layer of skin and its annexes. Therefore, more and more cosmetics use protein and peptide ingredients to enhance product efficacy. Often sourced from plants, algae or fungi, these ingredients can be used in all types of cosmetics (lotions, emulsions, gels, powders). The most frequently used are vegetable proteins, including wheat gluten rice, oats, sunflower, peanuts, almonds, and soy globulins. Wheat protein is an excellent cereal protein with high elasticity when hydrated, ideal for skin moisturizing applications. Soy protein is also widely used for its gelling and emulsifying properties.

It cannot be ignored that these proteins in action may be a source of type I allergen (especially wheat protein). They are classified as "new allergens" due to possible adverse reactions (asthma, itching or anaphylactic shock) from exposure to them. Because of their potential allergenicity, the quantity and type of protein present in the raw material must be determined by accurate analytical testing. Read more
