Hazard Statements
Flammable gas Contains gas under pressure; may explode if heated Toxic if inhaled Causes severe skin burns and eye damage Very toxic to aquatic life
Short-term Exposure Effects
Rapid evaporation of the liquid may cause frostbite. The substance is corrosive to the eyes, skin and respiratory tract. Exposure could cause asphyxiation due to swelling in the throat. Inhalation may cause lung oedema, but only after initial corrosive effects on eyes and/or airways have become manifest.
Long-term Exposure Effects
Repeated or chronic inhalation of the vapour may cause chronic inflammation of the upper respiratory tract. Lungs may be affected by repeated or prolongated exposure. This may result in chronic obstructive pulmonary disorders (COPD).
Routes of Exposure
The substance can be absorbed into the body by inhalation.

Expert Verdict

Corrosive and caustic at high concentrations; severe respiratory irritant; causes chemical burns to eyes and mucous membranes; strict pH ceilings mandated in EU.

Frequently Asked Questions

Is Ammonia safe in cosmetics?

Corrosive and caustic at high concentrations; severe respiratory irritant; causes chemical burns to eyes and mucous membranes; strict pH ceilings mandated in EU. The EU classifies Ammonia as "restricted". Safety rating: MODERATE.

Is Ammonia allowed in the EU?

Ammonia EU regulatory status: restricted. Maximum allowed concentration: 6%. This is based on EU Regulation 1223/2009 and its amendments.

What does Ammonia do in cosmetics?

Ammonia functions as: pH adjuster, buffering agent. It is classified as a cosmetic ingredient in our database. CAS number: 7664-41-7.

What is the Margin of Safety for Ammonia?

adequate The Margin of Safety (MoS) is calculated using SCCS methodology. A MoS above 100 is generally considered safe. Use the MoS Calculator tool to calculate MoS for your specific formulation and product category.

Is Ammonia classified as hazardous under GHS?

Ammonia carries a GHS signal word of "DANGER". Hazard statements: Flammable gas Contains gas under pressure; may explode if heated Toxic if inhaled Causes severe skin burns and eye damage Very toxic to aquatic life. This classification is based on the ILO/WHO International Chemical Safety Card and ECHA C&L inventory data. Note: GHS classification applies to the pure substance — at cosmetic use concentrations, hazard thresholds may not be met.
