Helianthus annuus (sunflower) seed extract is made from the pressed seed meal of sunflower seeds. It is a multi-benefit ingredient proven to help protect skin and hair from environmental damage. This is not surprising when you consider the treasure trove of antioxidants and polyunsaturated fatty acids found in sunflower seeds. Among the nutrients are various tocopherols (forms of vitamin E), polyphenolic antioxidants, minerals such as selenium, copper and zinc, and amino acids.
Typical usage levels in cosmetics range from 0.024-0.05%, with higher amounts typically used in leave-on moisturizers and lower amounts used in soaps, shampoos, and conditioners. These amounts are considered safe for use in cosmetics, but this ingredient should be carefully considered if you have a known food allergy to sunflower seeds.
Outside of the cosmetic realm, recent research has shown that sunflower seeds have antimicrobial properties capable of making water safer to drink in countries without widespread access to clean tap water https://www.paulaschoice.com/ingredient-dictionary?q =Helianthus%20Annuus%20Flower%20Extract
