🚨
NOT RECOMMENDED
Danger Score: 7 (Lower is safer)
Quick Answer: Potassium Hydroxide not recommended for 1-2 year old toddlers when used in topical products. Watch for toddler-specific sensitivities.

ℹ️General Overview

For toddlers (1–2 years), potassium hydroxide can irritate or burn the skin if it’s not used in a very low, well-formulated concentration. It’s allowed in some products but manufacturers are required to limit how it’s used.

What to Do

Choose products made for toddlers and babies from reputable brands. Prefer rinse-off products (like shampoos) over leave-on creams that list potassium hydroxide. Don’t apply products with this ingredient to broken, red, or very sensitive skin. If you must use a product that lists it, do a small patch test on a less sensitive area first and rinse immediately if there’s stinging.

⚠️Warnings

Avoid using on newborns and infants, avoid on broken or irritated skin, and keep away from the eyes. This ingredient is subject to formal use and concentration limits in cosmetics under EU regulations and industry safety reviews (Cosmetic Ingredient Review); those limits exist because of its irritation and caustic properties. Also, some product-verification programs restrict this ingredient unless manufacturers provide safety data—so prefer products that are explicitly formulated to avoid irritation.

Safety Risk Labels

This ingredient has the following documented risks:

Banned: This ingredient is restricted for use in cosmetics under the EU Cosmetics Directive and industry safety reviewers (CIR) say it may only be used with limits or special formulation controls. Regulatory listings and product-verification rules mean some products are not allowed to contain it without strong safety proof.
Organ Risk: European hazard labeling (EU GHS) and Environment Canada classify this chemical as toxic or harmful to organs and list it as a medium human-health priority. That means it can damage non-reproductive organs with unsafe exposures.
Long-Term Risk: Environment Canada’s assessment and EU hazard classifications indicate concerns that repeated or long-term exposures could lead to lasting health effects. Workplace rules also limit allowable exposure, showing regulators see risk over time.
