Is this safe for adults to use 4 Methylbenzylidene Camphor?

⚠️
USE WITH CAUTION
Danger Score: 5 (Lower is safer)
Quick Answer: 4 Methylbenzylidene Camphor use with caution for adults when used in topical products. Adults generally have higher tolerance.

ℹ️General Overview

For adults: this ingredient is not considered safe enough to prefer. It gets into the body through the skin and has studies showing it can affect hormones and may build up over time. Some countries limit or ban its use.

What to Do

Look at the product ingredient list and avoid products that include 4‑Methylbenzylidene Camphor. Use mineral sunscreens (zinc oxide or titanium dioxide) instead. If you must use a product that contains it, use it sparingly and not every day; do a small patch test first. If you are pregnant, trying to get pregnant, or breastfeeding, avoid this ingredient.

⚠️Warnings

Studies and regulatory reviews list several concerns: it is absorbed through the skin (transdermal penetration studies, 2008), there is evidence of hormone-related effects in animals and some peer-reviewed human-focused work (peer-reviewed literature; 2007 study on prostate development after exposure), and it has been the subject of formal restrictions and opinions by regulatory bodies (scientific opinion concerning this ingredient, 2006; European Chemicals Agency). These are the sources behind the warnings—watch for products listing this ingredient and for any skin irritation or unusual symptoms after use.

Safety Risk Labels

This ingredient has the following documented risks:

Hormones: Multiple animal studies and expert reviews show this sunscreen ingredient can change hormone activity (for example, estrogen effects in lab animals). A European scientific committee and peer-reviewed research flagged endocrine-disrupting effects, so it may interfere with natural hormone development.
Confuse Hormones: Lab studies report this chemical acts like or changes hormone signals in animals. Peer-reviewed papers and regulatory reviews describe it as a substance that can mimic or alter hormonal messages, which can confuse growing bodies.
Fertility: Animal studies found developmental and reproductive changes at low doses, and the European Chemicals Agency lists it as a possible human reproductive or developmental toxin, indicating a real risk to future fertility or development.
Absorbed: Research on skin penetration and a regulatory opinion both show this ingredient is taken up through the skin after topical use, so it can get into the body rather than staying only on the surface.
Builds Up: Reviews and measurements suggest the ingredient can accumulate in people, and studies report it can build up in wildlife, so repeated use may raise body levels over time.
Banned: Regulatory opinions and rules restrict its use in cosmetics in some places; it is subject to limits or bans rather than being freely allowed everywhere.
Long-Term Risk: Because it can be absorbed and appears to persist or accumulate in people and wildlife, experts warn it may lead to health effects after repeated or long-term exposure.
Environmental: Environmental assessments and peer-reviewed studies find it is persistent and bioaccumulative in wildlife, meaning it can harm ecosystems after release (for example, from wash-off into water).
