Lash XTNDR Tubing Mascara

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

A synthetic polymer used to thicken and stabilize cosmetic formulas. The polymer chains are too large to penetrate skin; graded safe by the Cosmetic Ingredient Review and widely used in rinse-off and leave-on products.

Synthetic Beeswax is a manufactured blend of long-chain esters designed to mimic natural beeswax's texture and melting point, used as an emulsion stabilizer and thickener in balms, sticks, and creams. CIR reviewed it alongside other cosmetic waxes and concluded it is safe as used, a conclusion the panel revisited and left unchanged after a later look at additional data.

A wax ester derived from jojoba oil that closely resembles the skin's own sebum esters, used to soften and smooth skin. Available safety data has not flagged meaningful irritation or sensitization risk at cosmetic use levels.

A common emulsifier and texture-softener made from glycerin and stearic acid. CIR review of this class found no evidence of reproductive, carcinogenic, sensitizing, or phototoxic effects in the studies examined.

A fast-evaporating solvent used to carry actives and give toners a light, "clean" feel; at the concentrations used in classic astringents it can be genuinely drying or irritating with repeated use, especially on dry or compromised skin, though it is not inherently toxic and is a normal, well-studied cosmetic ingredient.

A naturally occurring fatty acid (also made in the body and found in many foods) used to thicken lotions and help stabilize cleansing bars. It is one of the most well-studied emollient ingredients and is not a meaningful irritant at cosmetic use levels.

A saturated fatty acid found in palm oil and naturally in the skin, used as an emollient to soften and condition skin. It is one of the most studied fatty acids and is well tolerated.

Ammonium Acrylates Copolymer is the ammonium salt form of an acrylic acid based polymer used to thicken formulas, hold pigment in place, and help mascara or liquid liner form a flexible film once it dries. CIR reviewed the acrylates copolymer family and concluded they are safe in current practices of use, and a 30% concentration of the material tested as practically nonirritating.

A buffering agent used in small amounts to maintain or adjust the pH of formulas to keep them skin-friendly. It is not added as an active ingredient but to keep the product at a safe and stable pH level.

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 glycol used very widely in Korean and Western skincare as a lightweight humectant, solvent, and gentle preservative-booster, often in place of traditional preservatives. It has a low reported irritation rate at use levels and is graded low concern in published assessments.

A preservative and antioxidant that helps prevent microbial growth and oxidative degradation in formulas. Published assessments support its use at cosmetic levels.

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.

Sodium dehydroacetate is a preservative that fights bacteria and fungi in water-based formulas, typically used alongside other preservatives at up to 0.6% (as the acid) and not permitted in aerosol sprays. CIR's panel has reaffirmed since 1985 that it's safe as used, based on it being practically nonirritating and nonsensitizing across many clinical tests, though the panel has also noted a small number of published hypersensitivity case reports set against very widespread use.

A lightweight humectant and solvent similar in role to propylene glycol, used to carry actives and give lotions a lighter feel. CIR has reviewed it and considers it safe as used in cosmetics.

A polyethylene glycol ether of lauryl alcohol, used as a mild surfactant and emulsifier in cleansers and other rinse-off products. CIR assessments support the safety of laureth surfactants in cosmetics, and they are often chosen for their mildness.

A light, low-odor glycol used as a solvent and humectant, extremely common in Korean toners and essences. It has a low reported irritation rate and is graded low concern in published assessments.

A plant-derived emollient and preservative formed from glycerin and caprylic acid (coconut) that helps retain moisture and supports formula stability through mild antimicrobial activity.
