What is Sea Salt?

Sea salt originates from the evaporation of seawater, yielding coarse crystals mainly of sodium chloride accompanied by trace minerals like magnesium, calcium, and potassium. In cosmetics, it appears in exfoliating scrubs, facial cleansers, body polishes, and oral care items. Its jagged granules deliver mechanical abrasion, buffing away dead surface cells for refined texture. Beyond exfoliation, sea salt draws moisture into the skin as a humectant, enhancing plumpness in formulas. It bulks up products for better structure, controls viscosity for optimal spreadability, masks off-notes in scents, and aids cleaning in toothpastes. This versatile, eco-sourced ingredient suits water-based emulsions and anhydrous blends, prized for its sensory grit and multifunctional utility in daily routines.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Abrasive
Provides gentle mechanical exfoliation and polishing, helping remove surface dead skin cells and improve smoothness and slip in scrubs and cleansers.
Humectant
Attracts and holds water in the stratum corneum, boosting hydration and plumpness; commonly used in moisturizers, cleansers, and hair conditioners.
Bulking agent
Increases mass/volume to build structure and improve handling, commonly used to adjust feel, spread, and cost-in-use without acting as a primary active.
Masking
Reduces perception of unpleasant odors or tastes by neutralizing them or covering them with more acceptable sensory notes.
Oral care agent
Supports oral hygiene performance (cleaning, freshening, plaque control, sensitivity support) in toothpaste, mouthwash, and related products.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.

Benefits

- Delivers cleansing action by mechanically removing dirt, oil, and buildup.
