MAGNESIUM BROMIDE.

Questionable CAS 7789-48-2 / VISCOSITY CONTROLLING

Magnesium Bromide (MgBr2) is an inorganic salt primarily recognized in cosmetic formulations for its ability to modify product texture. While magnesium ions generally offer potential skin benefits, direct clinical evidence for this specific compound is absent, and it carries a moderate risk of skin irritation.

Summary

Viscosity controlling

Science

Mechanism of Action

The proposed biological effects are primarily attributed to the magnesium ion (Mg2+) component. Mg2+ is understood to enhance wound healing by increasing hyaluronic acid synthase activity and subsequent hyaluronic acid production within epidermal keratinocytes. It also contributes to polyamine synthesis and demonstrates protective effects against UVB-induced cellular damage in keratinocytes. Research involving magnesium chloride (MgCl2) indicates Mg2+ can inhibit epidermal differentiation while promoting cell migration, a process potentially mediated by elevated matrix metalloproteinase-7 (MMP7) expression. Topically applied magnesium may also stimulate collagen synthesis and angiogenesis, further supporting skin repair, and a 1.9 M magnesium solution has been observed to significantly increase skin hydration.

Sensitization risk Moderate

Magnesium bromide has an FDA Unique Ingredient Identifier (UNII: 2VC6P60SLN). Under GHS classification, it is categorized as a Skin Irritant Category 2 (H315) and an Eye Irritant Category 2A/2B (H319), indicating it causes moderate skin and serious eye irritation. It does not possess individual approval as a standalone chemical but may be incorporated as a component within products covered by a group standard.

Verdict

Questionable

Magnesium Bromide's primary utility is as a viscosity controller. However, its classification as a moderate irritant and the absence of specific clinical efficacy data for this salt make its use in precision skincare questionable.
