Ingredients Analysis (10 found)

Homosalate

🚨6/10

For toddlers and preschoolers (ages 2–5): homosalate is a chemical sunscreen ingredient with moderate concerns because it can get into the body and some safety reviews show possible hormone and contamination issues. It’s not ideal for regular use on young children when safer alternatives exist.

Hormones - Lab studies and a 2021 safety opinion found signs that homosalate can affect hormone systems, including weak activity at androgen (male-hormone) receptors. This means it may interfere with normal hormone signals in children.

Confuse Hormones - Cell-based tests showed homosalate can act at hormone receptors and block normal signals. A scientific safety committee reported limited evidence of this hormone-like activity, so it can confuse hormone messaging in the body.

Fertility - A regulatory assessment of salicylate esters found animal studies showing developmental and reproductive effects at moderate doses. That suggests a possible risk to growth or future fertility with enough exposure.

Organ Risk - Environment Canada has classified homosalate as expected to be toxic or harmful to non-reproductive organs. That means repeated or higher exposures may hurt organs such as the liver or kidneys.

Absorbed - Clinical research showed sunscreen actives, including homosalate, can be measured in the blood after skin use. Other studies show it can help other chemicals penetrate the skin, so it is absorbed through the skin into the body.

Banned - Japan’s Ministry of Health restricts how homosalate may be used in cosmetics and sets concentration limits. Because of those limits, some regulated product programs also restrict its use.

Environmental - Environment Canada lists homosalate as suspected to be an environmental toxin. This raises concerns about harm to water life and the wider environment after release.

Long-Term Risk - Given the animal reproductive findings, organ-toxicity classification, and contamination concerns, repeated or long-term exposure could lead to health effects over time.

Confidence: MEDIUM

alcohol denat.

🚨6/10

For toddlers and preschoolers (ages 2–5), denatured alcohol can dry and irritate delicate skin and may let other ingredients soak in more easily. While cancer and reproductive risks are considered low, there are some official safety concerns and gaps in the data, so extra care is wise.

Organ Risk - A government health agency reviewed this chemical and listed it as likely to be toxic or harmful to human health and gave it a medium concern for people. That means repeated or heavy exposure could hurt organs (for example liver or lungs) if someone gets enough of it over time.

Absorbed - Lab and animal studies show denatured alcohol can act as a penetration enhancer. In other words, it can help other chemicals pass through skin more easily, and it can increase how much gets into the body when used on skin (shown in mouse and rat studies). This raises the chance of chemicals getting into a baby’s bloodstream when products contain it.

Long-Term Risk - Regulators and industry reviews note this ingredient is used in many places (including some food uses) and that safety assessments rely on limits and have data gaps. Because people can meet this chemical from several products and sources, small exposures can add up over time and increase long-term risk.

Confidence: HIGH

Octisalate

⚠️5/10

Safety information not properly formatted for easy understanding

Absorbed - Studies show octisalate can get through skin and raise blood levels after normal use. This includes lab skin tests and a randomized clinical trial that measured the ingredient in blood, and notes that it can also act as a penetration enhancer. The finding and the contamination note about salicylic acid mean it can reach the body and carry other substances with it.

Immune system - There are human case reports of allergic contact reactions to octisalate, showing it can trigger immune responses in some people (published dermatology case studies). These reports point to real allergy risk for sensitive children.

Eczema - Published contact‑dermatitis case studies link octisalate to rash and eczema‑like reactions in people who are sensitive, so it can trigger or worsen eczema in some children.

Irritant - Clinical case reports and safety reviews note skin irritation and contact sensitivity from octisalate in some users, so it can cause redness, itching or rashes on sensitive baby skin.

Banned - Some safety panels and regulators place limits on how octisalate is used. The Cosmetic Ingredient Review (industry safety panel) sets concentration/use qualifications, and a national health authority set a concentration limit for some product types in its country, so its use is restricted in some places.

Environmental - A national environmental agency has flagged octisalate as a suspected environmental toxin, so it may harm wildlife or ecosystems if released widely.

Confidence: HIGH

Octocrylene

⚠️5/10

For preschoolers and young children (ages 2–5), octocrylene is not the safest choice. It helps sunscreens work better but can get into the skin and has been linked to allergic skin reactions and contamination in some products.

Absorbed - Multiple studies, including a recent randomized clinical trial and skin absorption lab studies, show octocrylene can get through the skin and enter the body. This means it can travel beyond the surface of the skin and reach the bloodstream.

Builds Up - Field and lab research found octocrylene in fish from rivers and peer‑reviewed work reports it can accumulate in animal tissues and people. This means repeated use can lead to the ingredient building up over time.

Immune system - Clinical case reports and a review of contact and photocontact allergy show octocrylene can cause allergic skin reactions in some people. That is a real immune response risk, especially for sensitive skin.

Organ Risk - Laboratory studies report octocrylene can produce excess reactive oxygen species that harm cells, cause mutations, and have been linked to heart-related effects in experimental work. These cellular effects can harm organs with repeated exposure.

Long-Term Risk - Because octocrylene can be absorbed, can accumulate in tissues, and can cause cellular damage in lab studies, there is concern about possible health effects after repeated long-term exposure.

Environmental - Environmental studies found octocrylene in rivers and showed it accumulates in marine organisms and can harm coral cells and mitochondria. This indicates a risk to wildlife and ecosystems when the chemical enters waterways.

Confidence: HIGH

fragrance

⚠️5/10

Perfume in baby products can cause skin irritation or allergies in 2-5 year olds. It is likely included for fragrance but should be used with caution.

Irritant - Fragrance mixtures often contain chemicals that can cause skin irritation, redness, or rashes, especially on sensitive baby skin.

Eczema - Fragrances are known triggers for eczema flare-ups and can worsen symptoms in babies with sensitive or atopic skin.

Asthma - Fragrance chemicals can release volatile organic compounds (VOCs) that may worsen asthma or breathing issues in babies and children.

Hormones - Some fragrance ingredients, such as certain phthalates, are suspected endocrine disruptors that may interfere with hormone development.

Absorbed - Certain fragrance chemicals can be absorbed through the skin and detected in the bloodstream, raising concerns for systemic exposure.

Breast Milk - Some fragrance components, including phthalates, have been detected in breast milk, indicating they can pass from mother to baby.

Banned - Some fragrance ingredients are banned or restricted in the EU and other countries due to health concerns.

Builds Up - Certain fragrance chemicals, such as some phthalates and musks, can accumulate in the body over time with repeated exposure.

Long-Term Risk - Long-term exposure to some fragrance chemicals has been linked to chronic health effects, including hormone disruption and allergic diseases.

Confidence: HIGH

Avobenzone

⚠️4/10

For preschool children (ages 2–5), avobenzone is not the safest option but can be used with care. Studies show it can get into the skin and sometimes into the blood, and there are worries about impurities from manufacturing. The risk is lower than for babies under 2, but it isn’t completely without concern.

Absorbed - Studies and a clinical trial show avobenzone can get through skin and be measured in the blood. This means it can be absorbed into a child's body after topical use (clinical plasma concentration study; transdermal penetration research).

Banned - Some authorities limit how avobenzone can be used. For example, Japan has rules that restrict its use or set concentration limits in cosmetics, so some products must follow those limits.

Long-Term Risk - The ingredient record flags high contamination concerns and lists possible impurities (for example benzoic acid, 4‑t‑butylbenzoic acid, benzaldehyde, p‑anisic acid, acetophenone, and dibenzoylmethane). These contaminants can raise long‑term health questions if present repeatedly over time.

Confidence: HIGH

Available safety assessments do not show any risks above a low level, and the ingredient concern list is empty with no bans or restrictions reported. Because no higher-level health or regulatory concerns were found, no specific risk labels apply.

Confidence: HIGH

tocopherol

✅0/10

For toddlers and preschoolers (2–5 years), vitamin E (tocopherol) used in normal skin products is generally safe and gentle. It helps protect skin and oils and rarely causes problems.

Confidence: MEDIUM
