Sea Silt ●
TL;DR. This ingredient primarily functions as an absorbent, bulking agent, and texture modifier in masks, scrubs, and cleansing products. It can also provide mild physical exfoliation depending on particle size.
What does Sea Silt do in a cosmetic formula?
This ingredient primarily functions as an absorbent, bulking agent, and texture modifier in masks, scrubs, and cleansing products. It can also provide mild physical exfoliation depending on particle size.
Is Sea Silt clean?
From a clean-beauty perspective, it is generally well accepted when properly purified and tested for heavy metals, microbial quality, and gritty particles. The main scrutiny is quality control, not inherent skin reactivity.
Is Sea Silt sustainable?
This material is mineral-based and not petrochemical-derived, but sourcing can raise concerns if collection disturbs coastal or seabed ecosystems. It is inorganic, so biodegradability is not the right lens, environmental fit depends more on responsible extraction and contaminant control.
Is Sea Silt COSMOS-approved?
It can be permitted under COSMOS natural and organic products when it is naturally occurring, physically processed, and compliant with extraction and purity requirements. Its Green Chemistry profile is mixed, with low synthesis burden and inert chemistry, but limited renewability and site-specific sourcing impacts.
How does Sea Silt work chemically?
This material is a heterogeneous inorganic mixture typically containing silicates, carbonates, mineral salts, and trace metal oxides, with performance strongly tied to particle size and purification. Use levels vary widely by format, from low single digits for texture to much higher levels in rinse-off masks, and formulators manage dispersion, abrasion, and microbial specifications.
