Ginseng Coffein-Shampoo

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

A common foaming cleanser, milder than SLS. Fine for most people in a rinse-off product.

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

A coconut-derived, mild foam-boosting surfactant closely related to cocamidopropyl betaine. It is generally well tolerated in rinse-off products but, like its chemical cousin, can occasionally cause contact irritation on already-compromised or very reactive skin.

An ester combining lauryl alcohol and lactic acid, used as an emollient and conditioner in cosmetics. Sparse published data but consistent use without documented adverse effects.

A natural alkaloid and studied active ingredient in skincare, valued for its antioxidant properties and potential to promote local circulation and reduce puffiness. Topical application results in minimal systemic absorption, graded low concern in regulatory assessments.

A plant extract long used in traditional wound care and now common in "cica" soothing products, valued for calming redness and supporting the skin barrier. It is generally well tolerated, with rare contact allergy reported.

An energizing plant extract used in skincare preparations, known for antioxidant activity in cosmetic applications. Cosmetic safety assessments generally support its use, though like many botanical ingredients it may trigger reactions in very sensitive individuals.

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

A gentle, PEG-based emulsifier and solubilizer that blends sugar and fatty acid derivatives for stable formula incorporation. PEG compounds in cosmetics are non-penetrating and rinse cleanly from the skin.

A naturally occurring acid used to preserve and adjust pH in cosmetic formulas. It is generally recognized as safe at cosmetic use levels, with mild irritation possible on broken or very sensitive skin at higher concentrations.

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 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.

Dehydroacetic acid is a preservative regulated under the EU preservative annex with a set maximum concentration. Sensitization appears to be rare, though occasional contact dermatitis case reports exist, so people with reactive skin may want to patch test.

A common preservative and fragrance/solvent ingredient found naturally in many essential oils. It is well tolerated by most people at the levels used in cosmetics, but it is one of the 26 EU-designated fragrance allergens and can trigger reactions in people with an existing sensitivity.

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.

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.
