Rosy Pits Daily Deodorant

A corn-derived solvent and humectant that has largely replaced propylene glycol in "clean" formulas; CIR reviewed the alkane diol group and found use concentrations up to about 40 percent in leave-on products like deodorant sticks with no meaningful irritation signal.

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

A plant-derived water or extract used mainly as a soothing humectant filler. Evidence for dramatic skin benefits beyond mild hydration and soothing is limited, but it is well tolerated by most people.

The sodium salt of stearic acid, used mainly to firm up stick deodorant bases and as a mild cleansing/emulsifying agent; CIR's fatty acid salts review found only minimal to mild irritation in concentrated, undiluted testing and no restriction on cosmetic use.

Natural corn starch used to absorb excess oil and add body to cosmetic formulas. It is very well-tolerated and has a long history of safe use in personal care.

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

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

A glycerin derivative used as a skin conditioner and preservative booster, often paired with phenoxyethanol to allow lower total preservative levels. It has a low irritation and sensitization profile in safety reviews.

A fragrance fixative and solvent found naturally in balsams and used to help scents last longer. It is one of the 26 EU-designated fragrance allergens, with documented but uncommon contact sensitization.

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 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 silica-rich botanical extract traditionally used in skincare formulations for its potential antioxidant and mineralizing properties. Limited clinical data are available; use caution if you have a sensitivity to plant extracts.
