Messi Biology states that skincare is a science, and even more, an art of balance. Healthy skin maintains a delicate, slightly acidic environment (pH typically between 4.5 and 6.5). This natural “acid mantle” is a vital component of the skin barrier; it inhibits the growth of harmful bacteria, maintains microbial balance, and ensures normal enzyme activity. However, in the manufacturing process of skincare products, many functional ingredients (such as certain emulsifiers and active substances) are inherently alkaline, which can cause the final product’s pH to deviate from the skin’s ideal range. At this point, a “master of balance” is needed for precise regulation, and magnesium hydroxide skillfully plays this role.
Magnesium hydroxide, as an alkaline pH adjuster, works by neutralizing excess acidic protons in the formula, thereby slowly and steadily raising the system’s pH to a preset target. It differs significantly from traditional strong alkaline adjusters (such as sodium hydroxide, potassium hydroxide). The latter are extremely alkaline, akin to “potent drugs,” and can easily lead to “overcorrection” due to localized excessive alkalinity during addition. This not only requires extremely precise equipment and operation but can also destroy the chemical structure of certain pH-sensitive popular active ingredients (such as Vitamin C, peptides, certain fermentation products, etc.), rendering them inactive or even irritating to the skin.
The advantage of magnesium hydroxide lies in its mildness and buffering capacity. Its alkalinity is relatively weak, and its solubility in water is low, meaning that its process of releasing OH- ions into the system is slow and continuous. This characteristic brings two major benefits:
- Operational Safety and Easy Control: Formulators can more easily and precisely adjust the product’s pH to the ideal range, avoiding drastic pH fluctuations caused by minor weighing errors or uneven mixing. This significantly enhances the stability and yield of the production process.
- Protection of Actives, Gentle on Skin: The stable neutralization process avoids local pH spikes, providing a gentle living environment for delicate active ingredients, maximizing the preservation of their efficacy. The resulting product pH perfectly matches the skin’s acidity, ensuring a comfortable application experience without causing stinging or barrier damage, making it especially suitable for sensitive skin.
Hebei Messi Biology Co., Ltd.’s specialized magnesium hydroxide for the skincare industry elevates this “art of balance” to new heights. The company’s product advantages directly address the pain points of skincare manufacturing:
- Pharmaceutical-grade High Purity: Skincare products are applied directly to the human facial skin, demanding the highest level of safety for raw materials. “Messi” magnesium hydroxide products achieve pharmaceutical-grade purity, with strict control over heavy metals and other harmful impurities, safeguarding the ultimate safety of skincare products.
- Excellent Suspension and Dispersion: Its products undergo special surface treatment, allowing them to disperse easily and evenly in oil-phase or water-phase systems without caking or sedimentation. This ensures the uniformity and stability of formula ingredients, resulting in consistent quality for every jar of cream or lotion.
- Outstanding Compatibility: It coexists well with various oils, polymer surfactants, and active ingredients without causing abnormal changes in formula viscosity, color, or odor, providing formulators with greater creative freedom and formula stability.
From luxurious creams to refreshing lotions and professional serums, magnesium hydroxide, this silent “master of balance,” works diligently behind the scenes. While it may not often appear on the forefront of marketing campaigns, it is fundamental to ensuring product efficacy, stability, and safety. And Hebei Messi Biology Co., Ltd., with its unwavering commitment to quality, is becoming a trusted partner behind many renowned skincare brands, jointly bringing more effective and safe skincare experiences to consumers.
