Betaine (Betaine)

Betaine is a naturally derived osmolyte most commonly sourced from sugar beet (Beta vulgaris) and widely used in cosmetic formulations for its skin-friendly humectant and conditioning performance. It helps attract and retain water while supporting the skin’s comfort by reducing the perception of tightness and dryness, and it can also improve the sensory profile of products by enhancing softness and slip. In surfactant-based systems, betaine is valued for its mildness-boosting effect, helping to cushion cleansing formulas and support a smoother feel on skin and scalp. Compatible with a broad pH range and suitable for sensitive-skin concepts, betaine is found in facial and body moisturizers, serums, toners, shampoos, conditioners, shower gels, micellar waters, and intimate or baby-care formats where hydration, soothing comfort, and gentle cleansing are key positioning benefits.
