Science behind mehndi Stain
Science behind mehndi stain Mehndi powder- A mehndi powder of good lawsone content of atleast 2-3 percent should be used.Though freshness is an important factor ,it is not alone the sole factor determining color of henna. A poor fresh crop can have only Lawsone content. A good quality crop can have very good lawsone content and it if properly stored can be used for years. The lawsone content deteriorates on time. Light and heat can damage the mehndi quality. Keep away from sunlight and if possible refrigerate mehndi powder. Use only dry spoon for using mehndi. Water- Pure water should only be used. Distilled water can also be used. Distilled water reacts when it contacts with air and form carbonic acid as carbon dioxide dissolves in it.The pH value will be less than 7 and would give good stain. Essential oil- Henna has hennotanic acid which is hydrophobic. So water alone does not help release stain.Essential oil has terps or monoterpene alcohol which helps to release stain....
