Designed as a solution for deodorants, facial masks and makeup products, this latest addition to the CareMag® brand offers extraordinary water and oil absorbency – alongside many other advantages. CareMag® L is the newest addition to the CareMag® brand – a free-flowing, light-density magnesium carbonate compound powder with unique properties that offer extraordinary water and oil absorbency. Based on high-purity magnesium sourced from the Dead Sea, CareMag® L is a solution for deodorants, facial masks, makeup and other products that require powerful absorption properties.

Why is water and oil absorbency so important?

Water and oil absorbency are essential for many personal care and cosmetic products. By absorbing excess moisture and sebum, these products help keep skin cleaner, drier and more comfortable. Deodorants rely on high moisture absorbency to control perspiration and keep skin feeling fresh, while effective odor prevention further enhances performance. Makeup products such as primers, foundations and powders also depend on strong oil and moisture absorbency to prevent shine and caking, delivering longer-lasting wear, improved performance and greater comfort throughout the day.

CareMag® L has unique advantages for your industry

ICL’s Specialty Minerals Division is known for a customer-centric approach that pairs specific needs with groundbreaking solutions. CareMag® L is specifically designed for specific market categories:

Deodorants Facial Masks Makeup
As an ingredient in deodorants, CareMag® L functions both as an absorbent of excess sweat, and as a neutralizer of odorous volatile acids. As a face mask ingredient, CareMag® L helps absorb excess sebum that often traps dirt, pollutants, and dead skin cells – thus reducing the risk of congestion and blemishes. CareMag® L promotes makeup product stability and longevity due to its excellent moisture and oil absorbency properties.

What makes CareMag® Special?

CareMag® L’s uniqueness stems from a variety of characteristics. Two stand out in particular:

Particle Size Distribution Water Absorbency
CareMag® L is a smooth powder with a narrow particle distribution, whose size distribution are 9 microns (as typical). When applied on the skin, this trait translates into a fine, homogenous layer. Compared to other solutions, CareMag® L has extraordinary water absorbency, reaching saturation at 250% (water % by weight).

CareMag®: ICL's Magnesium Touch

ICL offers a vast magnesium-based solution range. Manufacturing magnesium oxides, hydroxides and carbonates, ICL uses two production facilities and distinct methods to develop solutions that respond to specific challenges across numerous industries. ICL’s CareMag® brand harnesses the advantages of Dead Sea-sourced magnesium to set a new standard in body care. CareMag® solutions are known for their easy-to-apply and easy-to-formulate properties – and high purity levels. By converting Dead Sea magnesium chloride into magnesium compounds via a high heat decomposition reactor process – instead of chemical precipitation – high purity is effectively maintained. This production process, which adheres to sustainable standards, is also preferred due to the delivery of unique compound morphology, which is more in line with human body needs.

Comparing CareMag® L to Other Solutions

Internal testing conducted by ICL confirms that CareMag® L’s water absorbency exceeds that of other popular solutions:

Substance Typical saturation point (% by weight)
Starch 75%
Kaolin 50%
Magnesium Hydroxide 75%
CareMag L 250%

“CareMag® L is ICL’s latest breakthrough in magnesium compound innovation. By addressing the challenge of moisture absorbency with a natural-based solution, we’re expanding the possibilities for product manufacturers worldwide.”

Frequently Asked Questions

CareMag® L is a basic magnesium carbonate that may raise the pH in water base formulations. However, the influence on the pH in water-based formulations depends on other ingredients in the formulation and the amount of CareMag® L integrated. In dry powdery formulations or anhydrous formulations, there will be no effect on the pH.
ICL's production plant produces magnesium carbonate for food and pharma applications, which is manufactured under high quality standards to ensure its safety for human use. CareMag® L is a high purity magnesium carbonate and is free from harmful impurities such as lead and heavy metals. In addition, magnesium carbonate is inhalation safe according to safety standards.
Actually, other magnesium compounds such as magnesium oxide and magnesium hydroxide have other benefits and added values. For example, if a certain formulation requires high density powder, then magnesium hydroxide is the preferred choice. Other parameters such as flowability, particle size distribution or reactivity with other ingredients should be considered when choosing the ideal magnesium compound for a specific product formulation. At ICL, we are available to provide technical assistance and support regarding specific applications.
