Product Description
Bath Magnesium Salt Flake Powder is a high-purity magnesium chloride–based mineral blend designed for premium bath, spa, and wellness applications.
It combines fine magnesium salt powder with small translucent flakes, forming a unique hybrid structure that dissolves quickly,spreads evenly, and delivers a smooth mineral bathing experience.
Produced through advanced dehydration and crystallization of refined magnesium chloride hexahydrate, this product offers the same purity and mineral balance as granular bath salts, but with faster solubility and lower cost per use.
It provides an excellent source of bioavailable magnesium, helping relax muscles, relieve fatigue, and soften the skin naturally.
The flake–powder form ensures quick melting even at moderate water temperatures, making it ideal for personal care brands, spa centers, and wellness product formulators seeking both performance and value.
Bath Magnesium Salt Flake Powder is made by controlled dehydration and sieving of pure magnesium chloride crystals.
The resulting product features small, translucent flakes blended with fine crystalline powder, achieving the perfect balance between fast solubility and pleasant texture.
When dissolved in warm water, the mixture creates a soft, mineral-rich bath solution that promotes relaxation, relieves tension, and nourishes the skin.
Compared with traditional coarse bath salts, it offers faster melting, smoother water texture, and higher formulation efficiency, while maintaining high purity (≥98%) and excellent stability.
The product is odorless, free from harmful additives, and compliant with ISO 9001 wellness-grade manufacturing standards.
