What is BETAINE used for?

The huge benefits that Betaine provides in the world of cosmetics and personal care puts it in the spotlight. It can be found in a wide range of hair and skin conditioning products.
  • Skin care: It is a humectant that cures the skin to provide it with a plumped and dewy look. It is also considered anti-aging because it improves the natural hydration levels of the skin - reducing dryness and the appearance of wrinkles on the surface
  • Hair care: It is also added to hair care products in order to provide moisturization to the scalp. It detangles the shafts and makes them silky smooth. Because of its humectant properties, Betaine is the perfect solution for dry and damaged hair
  • Cosmetic products: It improves the texture of the products. It also thickens the formulations by almost 20%, which helps in improving the spreadability of cosmetics. Apart from this, Betaine makes the cosmetic products more hydrating and prevents them from drying out
