To be efficient, therefore, a propellant should have a large heat of combustion to yield high temperatures, and should produce combustion products containing simple, light molecules embodying such elements as hydrogen (the lightest), carbon, oxygen, fluorine, and the lighter metals (aluminum, beryllium, lithium).
Vitamin A - Retinyl Palmitate/ Retinol. Vitamin A is a fat soluble vitamin that is stored in our liver. It contributes to normal growth and development while keeping our eyes, skin and immune system healthy. Vitamin A plays a key role in maintaining health.
