Tea Tree Tingle Body Wash

Tea tree oil is used for its antimicrobial reputation in blemish-focused products, but it is a genuine, well-documented contact sensitizer, and its allergy potential rises sharply once the oil has oxidized from air exposure. Fresh, well-preserved, low-concentration formulations are much lower risk than old or improperly stored oil.

An essential oil rich in menthol and other terpenes. It adds a cooling, fresh note to products but is a known skin irritant and contact allergen, especially in leave-on products or for people with sensitive or inflamed skin. The oil oxidizes over time, increasing allergenicity.

Rosemary extract is widely used at low levels as a natural antioxidant to help stabilize oils and extend product shelf life, in addition to appearing as an active botanical in some formulas. It is generally well tolerated, with occasional mild contact reactions reported, mostly at higher leave-on concentrations.

Chamomile extract is used for its soothing and mild antioxidant reputation and is generally well tolerated. It belongs to the Asteraceae (Compositae) plant family, so people with a known ragweed or daisy-family allergy occasionally react to it and may want to patch test first.

A naturally occurring compound from peppermint and other mint plants that creates a cooling sensation and may have mild antimicrobial properties. It is generally safe in rinse-off products and low concentrations but can irritate or sensitize some individuals, particularly in leave-on formulas or higher amounts.

A mild amino acid-derived surfactant from coconut oil and glutamic acid, similar to its disodium counterpart. Valued in gentle facial and body cleansers for its low irritation potential.

A coconut-derived amphoteric surfactant used alongside primary detergents to soften foam and reduce irritation, similar in role to cocamidopropyl betaine. It has a generally good safety record, with occasional mild eye or skin irritation reported mainly in leave-on or highly concentrated rinse-off products.

A coconut-derived amphoteric surfactant used to boost foam and mildness in cleansers and shampoos. CIR has reviewed it as safe as used, but it is one of the more established contact-allergy triggers in personal care, usually traced to manufacturing impurities such as amidoamine and dimethylaminopropylamine (DMAPA) rather than the betaine itself. People with a history of eyelid or scalp dermatitis are more likely to react.

A humectant that draws water into the skin. One of the best-studied, best-tolerated ingredients in personal care.

A soothing humectant that helps skin and hair look conditioned. Very well tolerated.

A more stable, esterified form of vitamin E used as an antioxidant and skin-conditioning ingredient. It is a different substance from the vitamin E acetate implicated in vaping-related lung injury, which involved inhaling the oil, not applying it topically to skin.

Used in tiny amounts to set a product to skin-friendly pH. No concern at those levels.

A preservative that protects cosmetics from microbial growth. It is permitted in the EU and US and is graded as having low concern in published assessments. It is less widely known than parabens but carries a similar safety profile in use.

An undisclosed scent blend that can contain dozens of components. The single most common cause of cosmetic contact allergy, and the blend is not itemized, so you cannot see what is in it.
