Magic Cream

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

A solvent and emollient ester used in leave-on and rinse-off formulas. The CIR Expert Panel reviewed alkyl benzoates and found no irritation even at full strength, with typical use levels ranging from 0.0008 to 50 percent depending on product type.

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 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.

This branched ester is a CIR-reviewed emollient used to give creams and lotions a silky, fast-absorbing after-feel. It is generally rated non-comedogenic and has not shown irritation or sensitization concerns in the available safety data.

A lightweight, odorless emollient made by combining coconut or palm-derived fatty acids with glycerin. It spreads easily, feels non-greasy, and has a long history of use in skin and hair products with no meaningful irritation or sensitization signal.

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

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

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

An ester of palmitic acid and ethylhexanol, commonly used as an emollient and skin-conditioning agent. It is well studied and well tolerated 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.

An extract from oat kernels valued for drawing moisture into the skin and supporting the skin barrier. It is widely used in skincare and generally well tolerated, though very rarely people with gluten sensitivity or oat allergies may experience irritation.

A rich plant butter pressed from shea tree nuts, valued for softening and cushioning dry skin. It is generally well tolerated, though very rare allergic reactions have been reported and people with tree nut allergies who are cautious may want to patch test first.

A lightweight botanical oil pressed from rosehip seeds, used to nourish and condition the skin. It is generally well tolerated, though as a botanical extract it may rarely trigger sensitivity in individuals prone to plant allergies.

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 natural osmolyte produced by halophilic bacteria. Used for hydration and protective stress response, ectoin is well tolerated with emerging evidence for skin barrier support and soothing. No safety concerns flagged in cosmetic applications.

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

Broken-down plant proteins, often from soy or wheat, that bind water and improve skin feel. They are well tolerated and have been used safely in cosmetics for decades, though those with plant-derived allergens should patch-test if sensitive.

A fat-soluble vitamin C ester that is more stable than pure ascorbic acid. Published cosmetic assessments note it is well tolerated; it penetrates skin better than water-soluble forms and provides antioxidant support for sun-exposed areas.

A more stable, esterified form of vitamin E used as an antioxidant and skin-conditioning ingredient. It is a different substance from the vitamin E acetate implicated in vaping-related lung injury, which involved inhaling the oil, not applying it topically to skin.

A surfactant derived from stearyl alcohol with a higher degree of ethoxylation than Steareth-2, providing enhanced emulsification. It is graded safe for cosmetic use and well tolerated.

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.

An ester emollient used to soften and condition skin. The 2017 CIR safety assessment found it non-irritating and non-sensitizing across 415 surveyed formulas at concentrations from 1 to 33 percent.

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

An emulsifier made from cetyl alcohol and phosphoric acid, used to create stable creams with light conditioning properties. Well tolerated in finished products at cosmetic concentrations.

Dimethiconol is a silicone emollient closely related to dimethicone, used to add slip and a smooth finish to creams and serums. It shares dimethicone's long-standing safety record and is considered non-sensitizing and non-comedogenic in typical use.

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.

Xanthan gum is a microbial-fermentation-derived polysaccharide used to thicken and stabilize textures, similarly common in food. Cosmetic panel review of this and related microbial gums found them safe as used, with no meaningful irritation signal at typical concentrations.

A strong alkali used in tiny amounts to adjust the pH of cosmetics to safe, skin-friendly levels. At the pH found in finished products, sodium hydroxide is neutralized and well tolerated.

Sodium phytate is a plant-derived chelating agent used to bind trace metals and stabilize formulas, often as a preservative booster alongside other preservatives. Available safety reviews have not identified meaningful irritation or sensitization concerns at typical use 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 glycerin derivative used as a skin conditioner and preservative booster, often paired with phenoxyethanol to allow lower total preservative levels. It has a low irritation and sensitization profile in safety reviews.

The sodium salt of benzoic acid, used as a preservative in both foods and cosmetics. Decades of safety review support its use at typical cosmetic concentrations, with mild irritation the main reported issue in sensitive skin.

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

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 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.
