Overview
A swelling mineral clay used for suspension, opacity, and a distinctly earthy bath feel.
Source, harvesting, or manufacture
Mined from altered volcanic-ash deposits, then dried, milled, and graded.
Chemistry and composition
Layered aluminosilicate minerals with high surface area and ion-exchange capacity.
Scientific research
Adsorption is a material property, but consumer 'detox' claims overreach what a clay bath has been shown to do in the body.
Evidence labels apply to the specific bathing claim summarized here. They do not grade every possible use of the material.
Traditional use
Clays have long cosmetic and practical histories in cleansing preparations and poultices.
Bathing relevance
Creates cloudiness and slip and can hold water within its layered mineral structure; it does not truly dissolve.
Relaxation and sensory experience
Soft, earthy, opaque, and prone to settling if not dispersed.
Comparisons
- Unlike salts, bentonite suspends and settles rather than dissolving.
Practical use
Disperse gradually to minimize clumps. Rinse the tub promptly after use.
Safety
May dry or irritate sensitive skin. Powder handling should minimize inhalation, and tub residue can be slippery.

Frequently asked questions
Does this page mean Bentonite clay 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.
