Mineral 89 Hydrating and Plumping Daily Booster

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

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.

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

A glycerin-based polymer blend that holds water in formulas and improves spreadability without stickiness. PEG and PPG compounds at cosmetic concentrations are well tolerated and have a long history of safe 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.

Carbomer is a synthetic polymer used purely to thicken and stabilize gels and lotions, with negligible skin penetration due to its large molecular size. Safety reviews have found low toxicity and minimal irritation potential even in leave-on use.

A gentle, glucose-derived emulsifier and humectant used in skincare and cleansing products. It is valued for its mildness and compatibility with sensitive skin. Published cosmetic assessments support its safety in rinse-off and leave-on formulations.

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

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

Used in tiny amounts to set a product to skin-friendly pH. No concern at those levels.

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 starch derivative used in cosmetics to thicken formulations and improve texture. It has been used safely in food and cosmetics for decades and shows low irritation potential across rinse-off and leave-on products.

A polysaccharide produced through fermentation that thickens formulations and provides hydration. It is used across rinse-off and leave-on cosmetics with a low irritation profile, though very rare sensitivities to fermented polysaccharides have been documented.
