Well i don't really know how but follow these procedure..:

)

What to do:
  1. Mix together the Epsom salt and sea salt in the mixing bowl.
  2. Add glycerin to the salt mixture and mix through. The glycerin is not necessary, but it helps the colorant and oil get dispersed evenly through the salt. Rosemary: stimulating, invigorating, deoderizing

    Lavender: deoderizing and antibacterial

    Chamomile: calming

    Calendulla: healing

    Peppermint: stimulating

    Lime: refreshing

    Note: Essential oils have different grades and must never be taken internally or applied directly on the skin. Use as directed.

  3. Add a few drops of fragrance or essential oils. Fragrance oils will smell nice, but essential oils have therapeutic properties. Try using a couple of the following:
  4. Add a few drops of colorant. We recommend getting oil-based skin-safe colorant from a craft store or else leaving out the colorant.
  5. Wet your hands with tap water, add a drop of soap to your hands, then rub together to form a lather. Observe how much lather forms, then rinse off your hands.
  6. Fill a sink with water and add about 1/8 cup of salt mixture to it. Use your hands to stir the water to help the salt dissolve. With your hands still wet from the salt water, add a drop of soap to your hands and rub them together to form a lather. How much lather formed this time?
  7. Store the rest of your salts in a jar, keeping the lid on tight to keep moisture out. Use about 1/4 cup of the salts in your bath.

What's Happening?

Most likely you found it easier to form lather (and more of it!) when using the water with salt rather than the water with no salt. This is because of the difference between hard water and soft water.

Most households in America have hard water. Hard water has a high mineral content, usually with calcium and magnesium, whereas soft water contains less of these minerals. Calcium and magnesium ions in the hard water react with the soap, forming insoluble gray flakes called soap scum rather than a lather. This means you need more soap to get clean and the bathtub gets a grimy ring around it from the leftover soap scum. One way to soften hard bath water is to add bath salts. The calcium and magnesium ions in the water are replaced with sodium and potassium ions from the salt, allowing the soap to lather much more easily. (If your home has soft water, you may not notice too much of a difference in how well the soap lathers in the water with your bath salts and the water without the bath salts. However, the salt and essential oils will still have a beneficial effect on your skin.)

Another benefit of adding bath salts to your bath has to do with osmosis. Osmosis is the movement of water through a membrane (such as your skin) to achieve equilibrium. Your body contains water and salt, whereas an ordinary bath contains mainly water and very little salt. Therefore, water passes through your skin in an effort to balance the concentration of water and salt in you and in your bath. This excess water causes "pruning" (your fingers and toes wrinkle). Adding bath salts to the water causes a more equal balance of salt and water in both you and in the bath, so less water enters your skin and less wrinkling occurs. Salt is also thought to draw impurities and toxins out of your skin and soothes sore muscles!

Does boiling hard water make it soft?

Boiling hard water does not make it soft. Boiling water only removes some impurities and kills bacteria, but it does not change the mineral content that makes water hard. To soften hard water, a water softener system is needed.


Is hard water or soft water a greater solvent?

Hard water is generally a weaker solvent compared to soft water. This is because hard water contains minerals like calcium and magnesium, which can reduce its ability to dissolve other substances effectively. Soft water, on the other hand, lacks these minerals and is better at dissolving substances, making it a more efficient solvent.


How can Hard water convert into soft water?

Hard water refers to water that has very high mineral content, which affects its behavior in pipes and its affect on other chemicals like soap, where it often causes the formation of soap scum. Hard water also has a tendency to form deposits in pipes. Normally you wouldn't WANT to make water become hard, and there are systems for trying to reduce the "hardness" of water in the pipes of your home.


What is the difference between foaming capacity of hard and soft water?

Hard water has a lower foaming capacity compared to soft water because the presence of minerals such as calcium and magnesium interferes with the formation of soap lather. Soft water, on the other hand, allows for more effective lathering with soap due to the absence of these minerals.


Is river water hard or soft water?

River water is generally considered soft water because it contains low levels of minerals like calcium and magnesium. Hard water typically comes from sources like groundwater or wells, where it has passed through mineral-rich rocks.
