Overview
Evaporated seawater crystals used for mineral character, texture, and bath ritual.
Source, harvesting, or manufacture
Produced by evaporating seawater and refining or grading the resulting crystals. Trace composition varies by source and process.
Chemistry and composition
Mostly sodium chloride with smaller amounts of other ions. 'Trace minerals' does not imply a clinically meaningful dose.
Scientific research
Claims should focus on composition, dissolution, and sensory experience unless a specific preparation has direct evidence.
Evidence labels apply to the specific bathing claim summarized here. They do not grade every possible use of the material.
Traditional use
Salt-water bathing spans coastal, spa, and domestic traditions across many cultures.
Bathing relevance
Provides a familiar briny mineral character and can be blended in different grain sizes for visual and dissolving behavior.
Relaxation and sensory experience
Briny, crystalline, and available from fine to coarse grains.
Comparisons
- Unlike Epsom salt, sea salt is primarily sodium chloride.
- Dead Sea salt typically contains a different balance of magnesium, calcium, potassium, and chloride salts.
Practical use
Use cosmetic- or bath-grade material and allow coarse crystals to dissolve before entering the tub.
Safety
Salt water can sting broken skin and may feel drying to some people. Rinse the tub to reduce residue and slip risk.

Frequently asked questions
Does this page mean Sea salt is in Low Tide?
No. The library deliberately covers a broader historical formulation universe. Only a reconciled, owner-approved ingredient statement can establish product inclusion.
Does traditional use prove a health benefit?
No. It documents how people used or understood a material; clinical evidence is a separate question.
