Dry Skin Cream

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

A highly refined, purified oil that forms a light protective layer to slow water loss from skin. Cosmetic-grade mineral oil goes through purification steps that remove the contaminants associated with crude petroleum, and CIR has found it safe as used.

A palm/coconut-derived fatty ester used to soften skin and help dissolve oil-soluble UV filters. It sits fairly high on lab comedogenicity scales, so some acne-prone users report clogged pores, though this does not translate into a broader safety concern for general use.

A time-tested occlusive that seals in moisture and helps damaged skin heal, widely used in dermatology for wound care. Cosmetic-grade petrolatum must meet purity standards that remove the polycyclic aromatic hydrocarbons found in crude sources, and it is considered one of the most effective and well-studied barrier ingredients available.

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

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 refined mineral wax used to firm up ointment and balm texture and help form an occlusive barrier alongside petrolatum. Highly refined cosmetic-grade mineral waxes have long been reviewed as inert at the concentrations used in personal care products.

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 fatty alcohol used to soften skin and stabilize creams. Despite the name, it does not dry the skin.

An olive-oil-derived emulsifier, almost always paired with cetearyl olivate, that holds water and oil together and leaves a light skin-like finish. It is well tolerated and graded low concern in published assessments.

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

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.

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 chelating agent that binds trace metal ions to keep formulas stable and preservatives working properly. It is not a functional skincare "active" and only a very small amount is used, with minimal skin penetration expected.

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

A small-dose synthetic antioxidant that prevents oils and fragrance in a formula from oxidizing. Not shown to pose a toxicological risk at the levels used in cosmetics.

Alpha-isomethyl ionone is a violet-scented fragrance material and one of the EU-listed allergens requiring label disclosure. Documented sensitization is more common with this ingredient than with many other listed fragrance allergens.

Amyl cinnamal is a synthetic jasmine-like fragrance material on the EU list of allergens requiring disclosure. It has shown sensitizing potential in some human and animal studies, so fragrance-sensitive users may want to check the label.

A rose-scented fragrance ingredient found naturally in geranium and rose oil. It is one of the 26 fragrance allergens the EU requires to be labeled by name because a minority of people develop skin sensitization to it, though most users tolerate it without issue.

A sweet, hay-like fragrance ingredient naturally found in tonka bean and lavender. It is one of the 26 EU-designated fragrance allergens and is also subject to an EU maximum concentration limit in finished cosmetic products.

A spicy, clove-derived fragrance and flavor compound. It is one of the 26 EU-designated fragrance allergens because it can trigger contact allergy in sensitized individuals, though CIR review found it safe as typically used in cosmetics.

A floral, rose-like fragrance compound found in many essential oils. It is one of the 26 EU-designated fragrance allergens, meaning a documented minority of people can develop contact sensitization, so brands must disclose it above set thresholds.

Hydroxycitronellal is a lily-of-the-valley scented fragrance ingredient on the EU allergen disclosure list. It has well-documented sensitizing potential in patch-test studies, so it is worth checking the label if you have known fragrance sensitivities.

A citrus-scented fragrance component. Fine for most, but it oxidizes over time into a known contact allergen, so it must be labelled in the EU.

A floral fragrance component and one of the EU-labelled fragrance allergens. Usually fine, worth watching if you react to scented products.
