Refillable Deodorant

A natural plant-derived starch that absorbs moisture and adds texture to powders and dry formulations. It is derived from cassava root and is well-tolerated in topical cosmetic applications.

Commonly used to buffer and adjust pH in cosmetics and topical formulations. At the low concentrations used in rinse-off and leave-on products, it is well tolerated. Some individuals may experience mild irritation from high-pH formulations or direct skin contact with concentrated powder.

A linoleic-acid-rich plant oil used as an emollient and, in some small pediatric studies, associated with support of the skin barrier when applied to infant skin. It is well tolerated with a low reported rate of contact reactions.

A rich, solid-at-room-temperature butter extracted from cocoa seeds, valued for its intense emollient and conditioning properties. While generally well tolerated, it carries a higher likelihood of comedogenicity, so people with acne-prone skin may want to opt for lighter alternatives.

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.

A rich, solid-at-room-temperature oil that deeply softens dry skin and hair. It is well tolerated overall, but its high lauric acid content is considered comedogenic by many dermatologists, so it can trigger breakouts in people who are acne-prone.

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 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.

A rich plant butter pressed from shea tree nuts, valued for softening and cushioning dry skin. It is generally well tolerated, though very rare allergic reactions have been reported and people with tree nut allergies who are cautious may want to patch test first.

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.
