Rosemary Mint Strengthening Leave-In Conditioner

The base most products are built on. It carries the other ingredients and has no safety concern.

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

A long-chain quaternary ammonium compound used in rinse-off conditioners and leave-on styling products for conditioning and static control. It is well documented in cosmetic use with a strong safety record.

A blend of cetyl and stearyl fatty alcohols used to thicken lotions and soften skin. It is chemically unrelated to drying alcohols like ethanol, and the CIR expert panel has found fatty alcohols safe as used in cosmetics.

A fatty alcohol derived from stearic acid that thickens creams and gives them a smooth, non-greasy glide. It is one of the fatty alcohols the CIR panel reviewed together and found safe as used, with a very low reported rate of contact sensitization.

A nutrient-rich oil pressed from sweet almond kernels, used to soften and condition skin. It is generally well tolerated, though people with tree nut allergies should patch test first, as it can rarely trigger allergic reactions.

A fatty alcohol used to soften skin and stabilize creams. Despite the name, it does not dry the skin.

A citrate ester used as a solvent and plasticizer in cosmetics to dissolve active ingredients and adjust texture. It is well tolerated and widely used in formulations without documented safety concerns.

Cold-pressed oil from olive fruit, valued as a carrier and emollient in skincare formulas. Well tolerated across skin types and delivers fatty acids that support skin barrier integrity.

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.

A B vitamin (B7) included in cosmetics for skin and hair conditioning effects. It is graded with no known concerns in cosmetic assessments and is well tolerated across skin types.

A rich botanical oil from avocado fruit, used to nourish and soften the skin. It is generally well tolerated across skin types and provides conditioning benefits.

A plant-derived emollient high in linoleic acid, used to support the skin barrier. Generally well tolerated, though some formulators note mild comedogenic potential in heavier occluded applications.

A PEG-type emulsifier (ethoxylated cetearyl alcohol) that helps blend the water and oil parts of a cream. CIR concluded ceteareth ingredients are safe as used, with the one caveat that they are not meant for broken or damaged skin.

An aromatic plant extract rich in natural antioxidants, valued in skincare formulations for its protective properties. Published cosmetic assessments indicate it is generally well tolerated, though the botanical origin means some sensitive individuals may react.

A warming root extract with anti-inflammatory and antioxidant properties. Some individuals report mild warming or tingling sensations; those with sensitive skin should start with lower concentrations or patch test first.

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.

A small humectant and solvent molecule that helps other ingredients dissolve and helps skin hold water. It is one of the most studied cosmetic ingredients and is considered safe at the concentrations used in personal care products.

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 hydrating plant extract from sugarcane rich in amino acids and minerals. It conditions and softens skin and is generally well tolerated across skin types.

A cold-pressed oil from sweet orange peel with a bright, citrus scent, containing furanocoumarins that can cause phototoxic reactions (pigmentation and irritation) when exposed to sunlight. This oil is best reserved for rinse-off products or formulations where sun exposure is unlikely or protected, as it can trigger adverse reactions in reactive individuals on sun-exposed skin.

A citrus essential oil with a fresh scent, extracted from lemon peel. It contains recognized fragrance allergen constituents (limonene, citral) and can trigger contact reactions in fragrance-sensitive individuals. Additionally, citrus peel oils carry documented phototoxicity risk, meaning skin treated with the product should avoid direct sunlight.

A widely used preservative, safe at the legal limit of 1% or less. Often the "paraben-free" replacement.

Caprylyl glycol is a plant-derived humectant that also has mild antimicrobial properties, so it is commonly paired with other preservatives to allow lower overall preservative levels. Available data do not point to meaningful irritation or sensitization concerns at typical use levels.

A widely used emulsifier and solubilizer that has been in cosmetics and pharmaceuticals for decades. The CIR has assessed it as safe with no known concerns at typical cosmetic concentrations. As with any surfactant, some people with very sensitive skin may experience mild irritation.
