True Match Super-Blendable Foundation

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

A silicone that gives a smooth, soft feel and helps hold water in the skin. Inert and well studied.

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.

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

A silicone emulsifier combining polyethylene glycol and dimethicone to help blend water and oil phases in serums and primers. Limited but consistent data support its safety in cosmetic formulations.

An acrylic crosspolymer used to thicken and stabilize cosmetic products. Established use in cosmetics indicates minimal skin irritation potential at typical formulation levels.

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.

Pentylene glycol is a humectant and solvent that also offers mild antimicrobial support in formulas. It is generally well tolerated, with only rare reports of irritation, mostly in already sensitive or compromised skin.

Synthetic fluorphlogopite is a lab-grown mica look-alike made of layered magnesium aluminum silicate sheets with some fluorine substitution, used as a shimmer and pearlescent base in powders, eyeshadow, and skincare. CIR's expert panel reviewed irritation, sensitization, and genotoxicity data and concluded it's safe as used at reported concentrations up to 67%.

A quaternized clay mineral used to thicken and suspend products. CIR found it safe as used, though the mineral base means trace amounts of inhalable silica particles exist if the powder form is aerosolized. It is well tolerated in leave-on and rinse-off cosmetics when formulated properly.

A silicone-based conditioning agent that adds smoothness and soft feel to formulas. Silicones in cosmetics are not absorbed by the skin and rinse cleanly, making them well-tolerated for most users.

Ordinary salt, used in surfactant-based products like shampoos and body washes to adjust viscosity by interacting with the surfactant micelles. It has no meaningful toxicity concern at cosmetic use levels; the main practical downside is that too much can make a formula feel less mild.

A polyol ester emulsifier that stabilizes water-in-oil and oil-in-water emulsions with minimal irritation. Like other polyglyceryl esters, it is valued for its mildness and is used across a range of skincare and color cosmetics.

Hexyl Laurate is an ester of hexyl alcohol and lauric acid used as a light, fast spreading emollient that gives creams and makeup a silky, non greasy finish. CIR reviewed it within a group of 237 alkyl esters and found low potential for acute toxicity, irritation, and sensitization when products are formulated to be nonirritating.

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

An amino acid derived emulsifier made from stearic acid and glutamic acid that is increasingly used in natural and clean formulations. It is mild, biodegradable, and presents no known safety concerns for cosmetic use.

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

A soothing humectant that helps skin and hair look conditioned. Very well tolerated.

An inert mineral powder used as a filler and white base for color cosmetics. It is not the same as the antiperspirant aluminum compounds that trigger health concerns. Well tolerated and FDA-approved for cosmetic use.

A urea derivative used as a humectant to help skin retain moisture and improve hydration. Published safety assessments find it well tolerated at the use levels in cosmetics.

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.

A humectant that holds water at the skin surface for a more hydrated look. No safety concern.

A mineral pigment used to add opacity and soft-focus effects in cosmetics. FDA-approved for cosmetic use and graded low concern in published safety assessments.

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.
