Formula IngredientHumectantBetaine
INCI: Betaine
Betaine (trimethylglycine) is a naturally occurring amino acid derivative typically extracted from sugar beet (Beta vulgaris). It functions as an osmolyte, meaning it helps regulate cell water balance by attracting and retaining moisture without disrupting cellular function. In cosmetic formulations it acts as a humectant and skin conditioning agent, and when added to cleansing products it reduces irritation potential and improves mildness.

Is Betaine safe? Key considerations
Can Betaine cause irritation?
Low RiskBetaine is a naturally occurring compound in the body and in many foods. It is non-irritating and non-sensitising at all cosmetic concentrations. No EU CosIng Annex II or III restrictions apply. It actively reduces the irritation potential of surfactant-based formulations.
Does Betaine increase sun sensitivity?
No RiskBetaine does not increase photosensitivity. No sun protection precautions are required.
Is Betaine safe during pregnancy?
SafeBetaine is a naturally occurring substance found in many foods (spinach, beetroot, quinoa) and in the human body. It is considered entirely safe during pregnancy. No reproductive or developmental concerns are documented.
