Is this safe for adults to use Isobutane?

🚨
NOT RECOMMENDED
Danger Score: 6 (Lower is safer)
Quick Answer: Isobutane not recommended for adults when used in topical products. Adults generally have higher tolerance.

ℹ️General Overview

For adults: Isobutane is usually a propellant in spray products. It can irritate the skin, eyes and lungs and may cause skin allergic reactions in some people. Some governments limit its use because of possible contamination and safety concerns, so it’s best treated with caution.

What to Do

If you are an adult using a product that contains isobutane: use the product as directed (do not spray directly on broken skin), avoid inhaling the spray, keep the product away from heat and flame, and store it out of reach of children. If you have sensitive skin, test on a small patch before regular use. Choose non-aerosol alternatives if you experience irritation or if you are applying something around babies or young children.

⚠️Warnings

Warnings come from government and industry safety reviews: some authorities (Health Canada and EU cosmetics rules) place restrictions on its use; industry safety panels report it can be a skin irritant or allergen; and there is a contamination concern with butadiene. Avoid using aerosol sprays containing isobutane around infants and young children, avoid spraying near your face, and stop use and seek medical advice if you get redness, swelling, breathing trouble or other signs of a reaction.

Safety Risk Labels

This ingredient has the following documented risks:

Organ Risk: Isobutane has been classified as expected to be toxic or harmful to non-reproductive organs and flagged as a high human-health priority by a national environmental health agency, which means repeated or heavy exposure could harm organs like the lungs or liver (Environment Canada).
Banned: Use of isobutane in cosmetics is restricted in some jurisdictions and subject to limits or bans on use, concentration, or manufacturing methods (Health Canada; EU Cosmetics Directive).
Irritant: Strong human evidence shows isobutane can irritate skin, eyes, and lungs, so it can cause redness, stinging, or cough when people are exposed (Cosmetic Ingredient Review).
Asthma: Because isobutane is reported to be a lung irritant and carries occupational inhalation hazards, exposure can worsen breathing problems or trigger asthma symptoms (EU GHS hazard labeling; Cosmetic Ingredient Review).
Immune system: There is strong evidence that isobutane can act as a human skin toxicant or allergen, meaning it can trigger immune reactions in some people (Cosmetic Ingredient Review).
Eczema: Because it can cause skin allergy and irritation in people, isobutane may trigger or worsen eczema and similar skin conditions (Cosmetic Ingredient Review).
