Cosmetics Formulation Development

1. From a web page that says DMAE 4% understand that a 100g product contains DMAE 4G, but why DMAE ? DMAE 4% to actually use becomes 10-20%. Please explain. 2. Or is it because of the body? DMAE is 50% concentration, so should it be used as 8g in 100g product weight (equal to 8%) right?

INCI Name: Dimethylaminoethanol TARTRATE (50% concentration as Bitartrate form) Toner formula example DMAE 4% น้ำกลั่น 80-90% DMAE (SkinTight MD™) Liquid 10-20% สารกันเสีย 0.5%

3. Other products specified concentration Do I have to compare them all again?

Hello DMAE (SkinTight MD™) Liquid , the type sold by the company, will contain Active DMAE Biartrate 50% which will cool. Directed Active DMAE 20%, that means using DMAE (SkinTight MD™) Liquid 10% in the formula will be active DMAE 2% in the formula, usually the brand used DMAE will be used at the active rate DMAE = 0.5-2% which equals DMAE (SkinTight MD™) Liquid 2.5-10%
