Science
Mechanism of Action
Dolomite powder functions by actively drawing moisture from the surrounding environment and integrating it into the skin's deeper layers, thereby significantly boosting its inherent moisture retention capabilities. Concurrently, it efficiently absorbs surplus oil and impurities from the skin's surface. The magnesium component within dolomite is instrumental in promoting skin hydration, mitigating inflammatory responses, and reinforcing the skin's protective barrier, which can aid in preventing conditions such as acne and dermatitis. It imparts a soothing, cooling, and softening sensation, helps prevent rashes and pimples by reducing friction, and can also provide a gentle abrasive action for a smoother skin finish.

Dusting Analysis
Dolomite powder, especially in fine particulate form, poses a significant inhalation risk. Repeated exposure to fine dust containing respirable crystalline silica (quartz) can lead to severe lung conditions, including silicosis and potential carcinogenesis. Inhalation may also cause general respiratory tract irritation. Consequently, product formulations must be meticulously designed to minimize the generation of airborne particles.

Stability
Dolomite powder exhibits high stability, maintaining over 99% stability across most pH ranges. However, its stability is lowest at pH 2, indicating increased susceptibility to degradation in highly acidic environments. It reacts exothermically with strong acids, generating salts and carbon dioxide. For optimal shelf life, it should be stored in a dry, covered area to prevent caking due to moisture absorption.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Panel found naturally-sourced silicates, including dolomite as an impurity, safe in cosmetics when formulated to be non-irritating, but noted insufficient data for products that may be incidentally inhaled. Dolomite is generally recognized as safe (GRAS) by the FDA for enhancing mineral content in bottled water; for cosmetic use, compliance with US FDA GRAS for cosmetic-grade material is required. Heavy metal content must adhere to EU SCCS guidelines, specifically below 10 ppm for both lead and cadmium. Direct skin contact may cause irritation, and eye contact can result in moderate to severe irritation in industrial contexts, while dust inhalation can irritate the respiratory tract.

Verdict
Dolomite Powder presents a valuable multi-functional profile for comprehensive skin support, offering hydrating, oil-absorbing, and texture-refining benefits with low irritancy, but requires meticulous formulation to mitigate potential inhalation risks associated with fine powder.
