Quick Answer: Behentrimonium Methosulfate is generally considered safe for 1-2 year old toddlers when used in topical products. Watch for toddler-specific sensitivities.

ℹ️General Overview

For toddlers (1-2 years) this ingredient is usually low risk when used in normal shampoos and lotions. It helps soften hair and skin and is not commonly linked to serious problems at the low levels used in products.

What to Do

Use products with this ingredient as directed. Prefer rinse-off products (shampoos/conditioners) over leave-on if you are worried. Stop using the product if your child gets a rash, persistent redness, itchy skin, or any breathing trouble. For spray products, avoid spraying near your child’s face to reduce breathing exposure.

⚠️Warnings

Some animal and lab studies have shown reproductive or nerve-cell effects and there are limited reports of respiratory or allergic reactions (sources: Cosmetic Ingredient Review and published studies from 2014, 2015, 2016 and 2021). Also, expert review lists safe use with concentration limits. Because of those findings, avoid using high-concentration products, avoid applying to broken or raw skin, and watch closely for any rash, swelling, wheeze or difficulty breathing. If you see those signs, stop use and seek medical advice.

Safety Risk Labels

This ingredient has the following documented risks:

Immune system: Some studies of quaternary ammonium compounds report effects on immune responses and signs of allergic or respiratory reactions. A 2021 human study found altered toxicological endpoints after exposure to common quaternary ammonium disinfectants, which supports concern about immune effects.
Asthma: There is limited evidence that quaternary ammonium compounds can cause respiratory irritation or trigger allergic-type breathing problems. Human data showing altered toxicological endpoints after exposure raise concern that breathing issues or asthma could get worse in sensitive children.
Organ Risk: A human study reported changes in toxicological measures after exposure to common quaternary ammonium disinfectants, indicating possible harm to non-reproductive organs (for example, lungs or other systems) with repeated exposure.
Fertility: Animal studies in mice have shown decreased fertility or subfertility after exposure to quaternary ammonium disinfectants at moderate doses (see studies: "Exposure to common quaternary ammonium disinfectants decreases fertility in mice" and "Quaternary Ammonium Disinfectants Cause Subfertility in Mice by Targeting both Male and Female Reproductive Processes"). This shows real reproductive risk in animals that may be relevant with significant exposure.
