Is Horsetail clean?
From a clean-beauty perspective, this ingredient is generally well accepted and not a common restricted-list concern. As with many botanicals, the main watchpoints are extract quality, preservative system, residual solvent choice, and rare individual sensitivity.
Is Horsetail sustainable?
This ingredient is plant-derived, renewable, and expected to be biodegradable in typical extract form. Sustainability depends on responsible cultivation or wild harvesting, solvent choice, and supplier controls for contaminants such as heavy metals or pesticide residues.
Is Horsetail COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic when the plant source, extraction solvent, and processing aids meet the standard. It fits Green Chemistry best when made with water, glycerin, ethanol, or other approved lower-impact solvents and minimal processing.
How does Horsetail work chemically?
This plant-derived extract contains silicon-containing minerals, flavonoids, phenolic acids, and tannins, which can contribute to astringent feel and conditioning claims. Typical use levels are often about 0.1% to 5% depending on extract strength, and it is usually most compatible in mildly acidic to neutral water-based systems.
