24/7 Glide-On Waterproof Eye Pencil (Perversion)

A lightweight hydrocarbon that gives formulas a smooth, silky feel. Used in color cosmetics and sunscreens. Well tolerated and inert.

A lightweight, volatile silicone that gives serums and primers their silky slip and quick-evaporating finish. Human safety data are reassuring; the EU restriction on this ingredient in rinse-off products is about environmental persistence in waterways, not skin safety.

PEG/PPG-18/18 dimethicone is a silicone modified with polyethylene and polypropylene glycol chains, which lets it act as a co-emulsifier that holds water droplets inside a silicone base, useful for long-wearing liquid foundations and other water-in-silicone formulas. CIR's expert panel reviewed dimethicone copolyols as a group and concluded this ingredient is safe as used up to 10%.

A chemically produced wax derived from petroleum refining, used to add texture, viscosity, and occlusive properties to formulations. It is an inert ingredient with a long history of safe use in cosmetics and is well documented as non-toxic and non-irritating.

Hydrogenated Polycyclopentadiene is a synthetic hydrocarbon resin used in small amounts in mascara, lip products, and depilatory waxes to give a formula body and hold. It is described as chemically inert with negligible skin absorption, and it falls within a CIR review of related polyene and hydrocarbon polymers, though published ingredient specific irritation or sensitization data is thin compared to more heavily studied cosmetic polymers.

A synthetic polymer used to impart silky texture and film-forming properties in skincare. Nylon particles remain on the surface and do not penetrate or absorb systemically, with a long history of safe use in cosmetics.

This is a water-in-oil emulsifier made by joining polyglycerin with isostearic, polyhydroxystearic, and sebacic acids, used in creams, sunscreens, and makeup removers to hold oil and water phases together without added surfactants. It has not had its own dedicated safety review, but CIR has separately reviewed both the polyglyceryl fatty acid ester family and the fatty acids that make it up and found each safe in cosmetic use, which is supportive context rather than a direct finding on this exact molecule.

A synthetic polymer used as a gentle exfoliant in scrubs and peeling products. It is an inert, non-biodegradable microparticle with no known skin irritation or sensitization potential when used topically in cosmetic formulations.

A synthetic antioxidant approved in the EU and used at low levels to prevent product degradation and extend shelf life. Not absorbed through skin and presents no safety concern in cosmetic formulations.

An antioxidant that helps protect a formula and condition skin. Well tolerated.

Mineral pigments used to add color to cosmetics. Iron oxides are FDA-approved colorants with a well-established safety record in cosmetic formulations.

A naturally occurring mineral silicate that adds shimmer and light-diffusing properties to cosmetics. Cosmetic-grade mica is well tolerated and should be free of asbestos and talc contamination.
