Betaine (Trimethylglycine), with CAS 107-43-7, is a naturally derived quaternary ammonium inner salt widely used in cosmetics as a powerful humectant, skin - and hair - conditioning agent. It is naturally found in sugar beets, spinach, and other organisms, where it acts as an osmolyte to protect cells from dehydration. In cosmetics, it offers excellent moisture - retention, enhances skin barrier function, and improves hair softness, making it ideal for lotions, shampoos, conditioners, and cleansers. It is highly compatible with other ingredients, gentle on skin and eyes, and compliant with global cosmetic regulations.
- Superior Hydration: Attracts and retains moisture, preventing transepidermal water loss (TEWL) and keeping skin plump and hair hydrated.

- Gentle & Compatible: Non - irritating, suitable for sensitive skin; works well with surfactants, oils, and active ingredients like vitamins and hyaluronic acid.
- Hair Care Benefits: Reduces static, improves combability, and restores shine to dry/damaged hair.
- Incorporation: Dissolve in the cooled water phase (≤40°C) with stirring before adding to lukewarm emulsions.
- Stability: Avoid high temperatures (>60°C) during processing to prevent degradation.
- Packaging: Use moisture - proof containers to protect from clumping.
