Aluminum Chlorohydrate ●
TL;DR. This ingredient is an antiperspirant active that reduces visible wetness by forming temporary gel-like plugs in sweat ducts. It also has astringent effects that can help limit underarm moisture.
What does Aluminum Chlorohydrate do in a cosmetic formula?
This ingredient is an antiperspirant active that reduces visible wetness by forming temporary gel-like plugs in sweat ducts. It also has astringent effects that can help limit underarm moisture.
Is Aluminum Chlorohydrate clean?
From a clean-beauty perspective, it is a frequent restricted-list ingredient because many standards separate odor control from sweat suppression. It can also cause local stinging, itching, or irritation, especially after shaving or on compromised skin.
Is Aluminum Chlorohydrate sustainable?
This material is mineral-derived and industrially processed, and as an inorganic salt it does not biodegrade like plant-derived organic ingredients. In wastewater, it can bind to solids and move into sludge, so the sustainability question is mainly about mining, processing footprint, and metal loading.
Is Aluminum Chlorohydrate COSMOS-approved?
It is not permitted as an antiperspirant active under COSMOS natural or organic certification. Its Green Chemistry fit is limited because it comes from nonrenewable mineral feedstocks, is not biodegradable in the usual organic-chemistry sense, and relies on sweat-duct occlusion rather than simple odor management.
How does Aluminum Chlorohydrate work chemically?
This is not a single discrete molecule, but a family of basic metal hydroxychloride polymers and aquo complexes that hydrolyze in sweat to create an insoluble gel in the upper duct. It is commonly formulated around 10 to 25% active in acidic aqueous or anhydrous systems near pH 3.5 to 4.5, and it can be destabilized by high-pH systems, soaps, or strongly anionic polymers.
