Eczema+ Pre-Biotic Foaming Oil Cleanser

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

Another sugar-and-fatty-alcohol derived non-ionic surfactant, structurally close to coco-glucoside but made from a shorter (decyl, C10) fatty chain. It is a gentle cleanser generally well tolerated, though a small number of contact-allergy case reports exist, mostly in people with pre-existing skin conditions.

A gentle, sugar-derived surfactant that is milder than sulfates and works through natural emulsification without the irritation profile of harsher cleansers. It is well-established in rinse-off and leave-on formulations.

A mild non-ionic cleansing agent made from coconut fatty alcohols and plant sugars (glucose). It is widely used in sulfate-free shampoos and gentle cleansers and is one of the least irritating surfactants in common use.

A plant-derived emollient and emulsifier made from glycerin and oleic acid, typically from olives or canola. Softens skin while stabilizing oil-water formulas; well tolerated at typical use levels.

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

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.

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

Technically a liquid wax ester rather than a true oil, jojoba closely resembles skin's own sebum and absorbs without feeling greasy. It is well tolerated across skin types, including acne-prone skin, with no significant irritation or comedogenicity signal in the available data.

A biodegradable chelating agent that binds trace metals to stabilize formulas, often chosen as a gentler alternative to EDTA. It is readily degraded in the environment and poses minimal toxicity concerns at cosmetic concentrations.

A stable, saturated version of squalene, a lipid the skin already produces, now usually sourced from olives or sugarcane instead of shark liver. It is very well tolerated across skin types and helps reinforce the skin barrier.

Finely milled oat that the FDA recognizes as an over-the-counter skin protectant for temporary relief of minor itching and dryness. Well tolerated, including on eczema-prone skin, with rare contact allergy in people with pre-existing oat or cereal sensitivity.

A linoleic-acid-rich plant oil used as an emollient and, in some small pediatric studies, associated with support of the skin barrier when applied to infant skin. It is well tolerated with a low reported rate of contact reactions.

A rich, solid-at-room-temperature oil that deeply softens dry skin and hair. It is well tolerated overall, but its high lauric acid content is considered comedogenic by many dermatologists, so it can trigger breakouts in people who are acne-prone.

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.

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 phospholipid emulsifier from soy or sunflower that binds water and oil and helps other ingredients absorb. It is a natural component of skin membranes, well tolerated, and reviewed as safe as used; a soy-derived grade is not a meaningful concern for a soy food allergy because the protein is largely absent.

A larger, gentler alpha hydroxy acid than glycolic acid, used to exfoliate and to draw in moisture. It can still cause stinging or increased sun sensitivity at higher concentrations, so daytime SPF use is sensible, but it is generally better tolerated than glycolic acid.

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

Plant-derived sterols that function as emollients and barrier-supporting ingredients found naturally in many botanical sources. They are well tolerated in cosmetic formulations with no known safety concerns at typical use levels.

A mild surfactant and emulsifier made from lactic acid and lauric acid. The lactate component makes it less irritating than many other surfactants; generally well tolerated in both rinse-off and leave-on formulas.

Chamomile extract is used for its soothing and mild antioxidant reputation and is generally well tolerated. It belongs to the Asteraceae (Compositae) plant family, so people with a known ragweed or daisy-family allergy occasionally react to it and may want to patch test first.

Calendula extract is a traditional soothing botanical used in balms and after-sun formulas with a generally reassuring safety history. Like chamomile, it is part of the Asteraceae family, so cross-reactive contact allergy is possible for people already sensitive to ragweed or related plants.

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 lab-made version of a lipid naturally found in the outer skin barrier. It is added to creams and cleansers to help replace lipids that washing can strip away, and it is not linked to irritation or safety concerns.

A plant-derived lipid precursor found naturally in skin that supports barrier function and lipid composition. It is used in skincare formulations to strengthen the stratum corneum and is documented as well tolerated, though rare individual sensitivities may occur.

One of the three major ceramides naturally found in human skin. Ceramide AP plays a critical role in maintaining the skin barrier and is extensively studied as a safe, essential ingredient. It is derived synthetically or from plant sources.

A waxy sterol found naturally in skin and used in cosmetics as an emollient and emulsifier. It supports the skin barrier and is well tolerated across skin types.

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

A synthetic peptide sequence derived from or mimicking Epidermal Growth Factor, designed to support skin renewal and healing. Cosmetic-grade formulations show no systemic absorption at recommended levels and are well tolerated in topical use.

A key structural lipid naturally found in healthy skin that reinforces the barrier and improves hydration. It is well established in skincare formulations and assessed as having excellent safety across all skin types, including sensitive and compromised barriers.

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 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.

A widely used, gentle preservative also common in food. It is generally well tolerated, though it can occasionally cause mild, transient irritation in people with already-compromised or very reactive skin.

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