COSMETIC ADVANTAGES OF PRODUCTS FROM THE DEAD SEA
The value of minerals in the support of good health is becoming more recognized by millions of people. They are part of the structure of our connective and supportive tissues and are components of our hormones and enzymes, which are responsible for our biochemical life.
Minerals are the key to hydration, the retention of moisture in the various levels of our skin. As skin ages, its mineral levels are depleted, lessening its ability to conserve moisture. Minerals can restore moisture thanks to their hygroscopic characteristics. Thus minerals, if absorbed into skin cells, may enhance intracellular water capacity and add water to the skin tissue from within. For this reason Dead Sea Minerals are thought to be an important contribution to the skin's Natural Moisturizing Factor - NMF. Arad replenishes these minerals, keeping your skin healthy and young - looking.

The mode of action of Dead Sea Minerals in Cosmetics
We reviewed the beneficial effects of the Dead Sea's raw materials on the skin and the fact that their unique healing and beautifying powers have been recognized since ancient times. Cleopatra, considered the most beautiful woman in the world, went to great expense to obtain exclusive rights over the area. At her command, pharmaceutical and cosmetic factories were built. Their remains can still be seen today at Ein Bokek and Ein Gedi.
Following in the tradition of ancient times, about 50 modern plants now manufacture cosmetics and skin care products based on the nutrients extracted from the Dead Sea. Scientists at these plants have developed lines of mineral-rich products, which are exported all over the world.
The use of Dead Sea bath salts at home is an effective way to relax and absorb the minerals of the Dead Sea. Research has proven the efficiency of Dead Sea bath salts in alleviating skin diseases such as psoriasis, and treatment can be administrated at home by using about 2.2 lb. for each bath. It is also highly beneficial for relieving muscle tension or for simply relaxing and enjoying a rejuvenating experience.
The uniqueness of many Dead Sea cosmetic lines lie in the key ingredient - mineral mud. Dead Sea mud can either be applied to the entire body or just parts, and is also popular as a facial mud masque. Professor Zalmanovich, a leading American dermatologist, tested the Dead Sea mud masques on thirty women of a different age groups and varying skin tones. They found the facial mud masques stimulating, tightening, cleansing and invigorating, leaving the skin with a refreshing glow.

FORMULATION OF COSMETICS WITH DEAD SEA COMPONENTS
Over the past few years, thousands of units of cosmetic products containing either Dead Sea Mud (DSM) or various compositions of minerals from Dead Sea water have been marketed.
The first group of products, which contain high concentrations of DSM, mainly comprises various types of body and face masks that are highly viscous dispersions. The second group comprises various lotions and creams, in the form of oil-in-water and water-in-oil emulsions that contain minerals from the Dead Sea at low concentrations. The third group of products is composed of one-phase aqueous solutions that also contain minerals at low concentrations.
The composition of Dead Sea minerals is very unique, as shown in Table 1. The concentration of divalent cations, magnesium and calcium is very high compared with the monovalent cations, mainly sodium and potassium. In addition, the ionic strength of the solution is very high. These two factors have a tremendous negative effect on the formation and stability of dispersions and emulsions, and strictly limit their concentration to a few percent of the weight of conventional cosmetic formulation.
