CareMag® D: Giving deodorants the magnesium advantage

The popularity of natural deodorants – deodorants made from natural-based ingredients that replace aluminum and other chemicals – is constantly reaching new peaks. Today's consumers are become more aware of the benefits of skin products made with natural-based ingredients, and manufacturers are responding accordingly.

The growing demand for alternatives to traditional antiperspirants has spawned an enormous market category, and natural deodorants can be found on shelves just about anywhere. When it comes to natural-based ingredients that can replace aluminum in deodorants, CareMag® D is one of the most well-known – creating a category of its own.

CareMag® D is a great alternative to traditional aluminum-based antiperspirants due to its heightened moisture absorption ability, which keeps the skin dry and maintains unfavorable conditions for microbes that cause unpleasant body odor.

CareMag® D: The unique magnesium-based natural deodorant ingredient

CareMag® D is an inorganic magnesium hydroxide powder compound with a carbon particle surface treated via a unique patented process. Known for its ability to neutralize acids, magnesium hydroxide is commonly used as an antacid that relieves heartburn and acid indigestion. This ability to neutralize acids is used to reduce odors in the case of deodorants.

CareMag® D's magnesium carbonate-coated magnesium hydroxide functions as a great active ingredient for aluminum-free deodorants due to its alkaline qualities – and here's why: body odor is not created by sweat, but rather by bacteria that break down proteins and lipids prevalent in sweaty environments. This process generates odorous fatty acids. Due to its unique particle surface treatment, magnesium carbonate-coated magnesium hydroxide is highly effective in neutralizing these smelly fatty acids. 

In addition, thanks to its unique physical properties, CareMag® D's magnesium carbonate-coated magnesium hydroxide is highly effective as a moisture absorbent. When sprayed on surfaces, it acts as a desiccant and keeps these surfaces dry, eliminating the conditions needed for microbes to survive.

Better armpit care: CareMag® D

CareMag® is a brand of natural high purity magnesium-based solutions developed by ICL for a wide range of body care products, including soap, creams, ointments, facial masks, foot sprays and aluminum-free deodorants. The CareMag® product line includes solutions that contain magnesium oxide, magnesium hydroxide or magnesium carbonate. One of these solutions is CareMag® D.

CareMag® D is an innovative patented magnesium hydroxide-based product developed specifically for deodorant application use. Gentle on the skin, CareMag® D's unique particle surface treatment increases its performance as a reliable moisture absorbent.

CareMag® D is designed to absorb sweat and moisture, keeping the skin dry. In cases where sweat is not absorbed, CareMag® D will still neutralize odorous substances produced by bacteria. Deodorants containing CareMag® D can be incredibly effective in controlling body odor. CareMag® D gets the job done – without influencing the sweat glands.

CareMag® B joins CareMag® D as a magnesium oxide-based solution also developed for deodorants. Formulators seeking specific particles size distribution and other physical parameters – for example for body spray deodorants – may find that CareMag® B is better suited to address their needs. In the event tailor-made solutions are required for specific deodorant formulations, CareMag® B sometimes provides a more precise response.

CarMag® D in deodorants: The main benefits

CareMag® D is an ideal fit for natural deodorant products for many reasons. Here's a short breakdown:

  • Growing consumer awareness of healthy and safe ingredients: Increasing consumer awareness regarding the safety of the ingredients in personal care products has led to the initiation of consumer safety ranking indexes. Two of the most popular indexes are the Yuka Index, which is mostly popular in Europe and is accessible via a mobile application (https://yuka.io/en/app/), and the EWG index (https://www.ewg.org/skindeep/understanding_skin_deep_ratings/) which has gained traction in North America. Since magnesium oxide and magnesium hydroxide are safe ingredients, they contribute to the deodorants that contain them in terms of higher scoring. In fact, CareMag® solutions are not only safe, but actually contribute to our health since magnesium is an essential element that our body needs.
  • Natural ingredients trend: Many natural-minded consumers wish to make sure the ingredients in their deodorant are natural. CareMag® solutions are COSMOS certified as natural ingredients. In addition, they are defined as "Minerals Derived" with "Natural Index" = 1 according to ISO 16128-2: 2017.
  • Absence of risky impurities: CareMag® D is based on magnesium sourced from the waters of the Dead Sea via a unique process that provides highest purity magnesium hydroxide. CareMag® product line ingredients are lead, arsenic and heavy metal-free.
  • Aluminum-free alternative: Aluminum-based deodorants are effective, and yet more and more consumers have come to prefer natural-based ingredients in their deodorants. CareMag® D works differently than aluminum-based ingredients – rather than blocking underarm sweat ducts, they prevent wet armpits by absorbing moisture. A test that compared a deodorant with 15% CareMag® D to a deodorant with the same formulation that contained 15% aluminum salt exhibited better results for CareMag® D.

  • Gentle on the skin: CareMag® D is a mild natural-based ingredient and is therefore ideal for people with sensitive skin. Since CareMag® D is water insoluble, it does not react quickly and does not irritate the skin. CareMag® D is also considered gentler on the skin than sodium bicarbonate because it is insoluble, whereas sodium bicarbonate is soluble, reacts fast and attacks the skin's natural barrier. Testing CareMag® for skin sensitivity (repeated Insult Patch Test) provided a result of absence dermal irritation or sensitization.
  • The Dead Sea factor: The Dead Sea is well known for its abundance of minerals, which are used in many top-ranking personal care products. Choosing CareMag® as an ingredient positions deodorants within an esteemed list of products that contain Dead Sea minerals.
