Zinc Ricinoleate[1] ●
TL;DR. This ingredient is primarily used as a deodorizing agent, binding odor molecules rather than masking them with scent. It is common in stick, cream, and roll-on deodorants.
What does Zinc Ricinoleate[1] do in a cosmetic formula?
This ingredient is primarily used as a deodorizing agent, binding odor molecules rather than masking them with scent. It is common in stick, cream, and roll-on deodorants.
Is Zinc Ricinoleate[1] clean?
From a clean-beauty perspective, this ingredient is usually viewed as acceptable because it is not a fragrance allergen, ethoxylated surfactant, or formaldehyde releaser. Sensitivity reports are uncommon, though it salts can feel drying or reactive on compromised skin at higher levels.
Is Zinc Ricinoleate[1] sustainable?
It is typically made from castor-derived fatty acid plus a it source, so its carbon backbone is renewable while the metal portion is mineral-derived. The organic portion is expected to biodegrade, while it remains an elemental mineral and should be managed through normal wastewater controls.
Is Zinc Ricinoleate[1] COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic when produced from allowed castor-derived fatty acid and permitted it sources, with supplier documentation required. It fits Green Chemistry reasonably well through renewable fatty-acid feedstock and low-concern use levels, though the mineral portion is not renewable.
How does Zinc Ricinoleate[1] work chemically?
It is a it carboxylate built from a castor-oil-derived C18 hydroxy fatty acid, giving it a polar metal center and a long lipophilic tail. Typical deodorant use is about 0.5 to 3%, and it is water-insoluble, usually added through heated oil or solvent phases with solubilizers or glycols for uniformity.
