The Best Water Softener Salts for Sensitive Skin

Fact checked by Stephen Conklin

best water softener salt for sensitive skin

People with sensitive skin or skin problems deserve only the best water softener salt for sensitive skin.

Water softeners remove minerals and compounds in water that can cause limescale formation in plumbing and water fixtures while making water safe for people with eczema, psoriasis, seborrheic dermatitis, and other skin health conditions.

Water softeners require periodic regeneration to continue removing hard minerals from the water. Unfortunately, people cannot use just any water softener salt for regeneration.

Like any commercially available product, water softening salts vary in quality and performance. Three factors are crucial in choosing the right water softener salt for home use.

  • Purity: Water softener salts must contain at least 99% sodium chloride. It is essential to understand that water softening devices work by knocking off calcium carbonates and other hard minerals from the water and replacing them with sodium chloride. The more NaCl the salt contains, the more efficient its water softening capabilities.
  • Type: Water softening salts come in different types. These include rock salt, potassium chloride, solar salt, block salt, and evaporated salt. Salts for softer water have varying sodium chloride levels, with evaporated salt having the highest NaCl concentration of up to 99.99%.
  • Form: People looking for a water softener salt for sensitive skin must also consider the salt form. They can choose either pellets or crystals. Most homeowners use salt pellets because of their higher sodium chloride content and suitability for moderate to high water softening requirements.

Prospective buyers can also consider other factors. I will describe these attributes in the following product reviews and the succeeding buying guide.

The company’s Pure and Natural Water Softening Salt Crystals are some of the top-rated water softener salts homeowners can buy today. We can rely on these products to treat mild to moderately hard water issues.

Unlike Morton Clean and Protect, this product is a solar salt, which the company produced using natural solar evaporation. It is as natural as one can get while ensuring gentleness on sensitive skin.

Therefore, people with psoriasis, eczema, seborrheic dermatitis, and other inflammatory skin conditions will never have issues using the water softened with this salt.

Not only do these natural water softening crystals protect the skin and hair, but they also prevent hard water stains. Families can stop worrying about disgusting spots on their dishes, glassware, water pipes, showerheads, tiles, and other water fixtures.

It is one of the most effective products for safeguarding plumbing integrity.

Using this water softener salt is also a cinch because of its easy-pull tab that does not rip the whole bag and spill the contents. The top grip is solid, allowing anyone to lift and dump the contents into the brine talk with ease.

I also like its sodium content purity. Although I cannot find sufficient information about its percentage purity, I can only guess it is higher than 99%. It should make people more confident about its water softening performance.

Unfortunately, I found some users complaining about the natural water softening crystal’s sulfur smell. Moreover, its price is higher than other solar salt brands, making some potential buyers shun this product.
  • Recommended for households with mild to moderately hard water

5. CAI Diamond Crystal 50 Water Softener

Families with babies, young children, or members with skin problems can trust the Diamond Crystal Bright & Soft Salt Pellets to ease their worries. This product is one of the most effective water softener salts on the market and an excellent choice for people with sensitive skin.

This Diamond Crystal water softener salt removes calcium carbonates, iron, barium, and magnesium to provide the modern family with efficient water softening. Families will not worry about crusty faucets or rusty pipes again.

Its implications are also immense to people with skin conditions, such as seborrheic dermatitis, eczema, and psoriasis. Elderly people with thinner skin will also appreciate the water’s softness after treatment with this salt.

I appreciate the company for publishing its NaCl purity (99.8%), making it easier for other people to decide if this product is best for them or not. While it is not 100% pure, I still consider it exceptional because it is only 0.2 percent away from perfect. The 0.2% non-NaCl molecules will also not cause an allergic reaction to water softener salt.

Handling this Diamond Crystal water softener salt is a breeze because of its dual-handled bag design. Moreover, opening it is easy because there are tear marks to follow. One can use this salt in any water softening system, regardless of brand, series, and model.

However, its iron removal capability is modest at best, compared to other brands with iron-reduction formulations.
  • 8% pure NaCl for high effectiveness
  • Removes calcium carbonates, barium, and magnesium
  • Compatible with many water softener systems
  • Gentle on the hair and skin
  • Dual-handled bag design with easy-to-open tear marks

6. Cargill Diamond Crystal Potassium Chloride Salt Substitute

People with kidney problems or heart disease should consider replacing their NaCl-based water softener salts with the Diamond Crystal Potassium Chloride Salt Substitute. This product is an eco-friendlier and equally effective alternative to NaCl salt.

This water softening salt contains 99.1% pure potassium chloride, making it as effective as conventional NaCl-based salts.

When people use this water softener salt itchy skin, dry hair, and skin breakouts are never a problem. It is hypoallergenic, guaranteed never to cause skin irritations or inflammation.

I also trust this product to remove hard minerals from the water and protect plumbing against limescale formation. Families will love the effects on their bathing, washing, and other water-related activities. Lathering is more pleasant, and dishes and other objects will look and feel cleaner.

Consuming the water softened with this Diamond Crystal salt is also safer for people with high blood pressure and kidney problems.

Sodium naturally attracts water molecules, which can increase blood volume. The excess blood volume makes it harder for the heart to pump blood and the kidneys to produce urine. This health concern is never an issue with potassium chloride.

This Diamond Crystal salt is also eco-friendlier. People can use the drainage for animals to drink and water the plants. It will not produce unnecessary health effects, nor will it cause people to become allergic to water contaminants.

Unfortunately, this Diamond Crystal product requires a large amount to achieve the same results as a NaCl salt. In some cases, people might have to regenerate their water softeners more often.
  • 1% pure potassium chloride salt
  • Ideal for people with heart and kidney problems
  • Environmentally friendlier than NaCl salts
  • Compatible with all water softener models and brands
  • Hypoallergenic composition, guaranteed no skin irritation or inflammation
  • Not as efficient as NaCl salts
Despite this, I cannot deny this water softener salt’s safety, effectiveness, and eco-friendliness. People who value these attributes more than cost considerations should get this product as a more sensible replacement for conventional sodium chloride salts for water softeners.

What to Look for When Buying Water Softener Salts for Sensitive Skin


Buying a water softener salt for sensitive skin requires understanding several product attributes. One’s appreciation of these factors can also help answer the question, is water softener salt good for your skin? Here are the things potential buyers must look for:


The most crucial buying consideration is the water softening salt’s purity. It translates to water softening process effectiveness. Unlike salt-free water softeners, ion-exchange process-based water softener systems require cation-anion compounds known as salts to dislodge water hardness minerals from the water.

A water softening system contains resin beads with salts. When hard water passes through the resin beads, potassium chloride or sodium chloride crystals replace the hard minerals. Hence, the more NaCl or KCl the water softener system has, the more effective it is in softening water.

The percentage of either NaCl or KCl in the salt crystals or salt pellets is the product’s purity. The closer the rating is to 100%, the purer the salt. Hence, a pure grade sodium chloride will have 100% NaCl.

However, it is almost impossible to achieve 100% purity. A functional water softener salt for sensitive skin can only have a maximum purity of 99.99%, indicating that 0.01% are elements other than salt.

As a rule, one should pick water softening salt with a purity of at least 99%. Thankfully, all of the products reviewed in this article meet this requirement.


If you buy water softener salt, it would also be best to consider the type.

  • Rock salt – Rock salt for a water softening system has 95% to 98.5% purity. The impurities can cause mineral deposits in the brine tank and damage other water appliances, such as water heaters. These products often feature mined sodium chloride and are processed for water softening systems. The good news is that rock salt is inexpensive.
  • Evaporated salt – Many experts consider this product excellent water softener salt for sensitive skin because it contains 99.7% to 99.99% pure NaCl. This product often comes in pellet form and is popular for its water softening efficiency. Unfortunately, it is the priciest among the different water softener salt types.
  • Solar salt – Crystallized solar salt contains 99.6% to 99.8% pure NaCl, making it the second most effective water softening salt after the evaporated type. Its production is similar to the natural salt formation, allowing seawater to evaporate under the sun. Unfortunately, it is not suitable for households with very high water hardness levels.
  • Potassium chloride salt – There are many confusing articles about potassium versus salt. Many people think that salt only refers to NaCl and not potassium chloride. However, elementary chemistry dictates that salts consist of a cation (positively charged element) and an anion (negatively charged chemical).

Hence, NaCl and potassium chloride are salts consisting of cations sodium or potassium and the anion chloride. Hence, it would be a mistake to think that potassium chloride is not water softening salt.

For example, Morton potassium chloride pellets are some of the top water softener salts on the market. It is perfect for people who do not like dumping NaCl into the environment.


People who want to buy water softener salt products must also decide the form: pellets or crystals.

  • Salt crystals – Manufacturers of water softener salt crystals evaporate seawater naturally, allowing the brine solution to form large masses called crystals. These salt products are ideal for households with mild to moderate hard mineral concentrations.
  • Salt pellets – Water softener pellets are the product of vacuum evaporation, producing the highest purity (99.99%). Salt pellets are ideal for households with moderate to very hard water, making them better than natural water softener crystals.


In general, evaporated types of water softening salts are the most expensive, followed by solar salts. The most affordable are rock salts for water softeners.

Does a Water Softener Make Your Skin Dry


No, water softening systems do not cause dry skin. Hard water contains limescale-forming minerals, such as calcium carbonate and magnesium. Not only do these chemicals produce scale in plumbing fixtures, but they also exert their abrasive properties on the skin.

Hard minerals strip the skin of its natural oils, leaving it vulnerable to the effects of physical, chemical, and environmental forces. Removing natural skin oils can produce dryness, while the hard minerals can clog pores and cause acne, pimples, and other skin breakouts.

Water softening systems remove these hard minerals from the water or at least reduce them to safer levels. When people use softened water for self-care and hygiene purposes, they protect themselves against potential skin dryness, irritation, and inflammation.

That is why many healthcare experts also recommend using a water softener for eczema, psoriasis, seborrheic dermatitis, and other inflammatory skin conditions.

What Is the Healthiest Water Softener Salt

Evaporated salt is the healthiest water softening system salt. Other water softener salt types contain up to 5% non-salt chemicals. These minerals can adhere to brine tank components, requiring more frequent cleaning and undermining the water softening system’s lifespan.

Manufacturers force distilled water into mined salt deposits underground before pumping the salt backup for heat and vacuum treatment. The distillation process produces salt with 99.7% to 99.99% NaCl, although it might vary across brands and product series.

Removing as much as 99.99% of non-salt chemicals produces a hypoallergenic water softener salt, making it ideal for people with sensitive skin and other skin problems.

Solar salt is also a safe and healthy choice because it is 99.6% to 99.8% pure salt. On the other hand, rock salt can contain 1.5% to 5% other minerals.

Can I Use Food-grade Salt for Water Softener

Some water softening appliance manufacturers use just simple table salt for regenerating their systems. However, it is generally not advisable to use table salt on water softening units because of varying salt purity levels.

It would be best to remember that water softening system salts undergo purification to produce salt with almost 100% NaCl.

Conversely, one should not use food-grade quality salt for culinary or food processing purposes. People with heart and kidney problems should minimize their NaCl consumption because it attracts water, increasing blood volume and blood pressure.

Moreover, water softening salts can contain impurities unsuitable for human or animal consumption. It is wise to understand that the purification process only removes chemicals other than NaCl. It does not remove debris, dirt, stabilizers, anti-caking agents, and other substances.


The best water softener salt for sensitive skin safeguards water systems against limescale and rust formation. It also makes it more pleasant for people to take a bath, wash objects, and do other water-related activities without fretting about skin irritations, breakouts, and inflammation.

Picking a water softener salt for sensitive skin requires an understanding of product purity, appropriateness of the salt type, and the best possible salt form for one’s needs.
