Special Cleansing Gel

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

A primary cleansing surfactant similar in strength to sodium laureth sulfate, used in many "sulfate-lite" shampoos even though it is itself a sulfonate detergent. CIR concluded it is safe in rinse-off products; it can be drying or irritating for already-sensitized scalps at higher use levels, same as most anionic surfactants.

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.

A cellulose derivative used to thicken and stabilize formulas. It dissolves fully in water and does not separate or settle over time. It is well tolerated and widely used in gels, lotions, and serums.

Lavender essential oil naturally contains linalool, geraniol, and coumarin, several of the recognized fragrance allergen constituents, so it can trigger contact reactions in fragrance-sensitive users even though it is a "natural" ingredient. It is not a general hazard for most people, but those with a known fragrance allergy should treat it like any other essential oil.

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

A coconut-derived amphoteric surfactant used to boost foam and mildness in cleansers and shampoos. CIR has reviewed it as safe as used, but it is one of the more established contact-allergy triggers in personal care, usually traced to manufacturing impurities such as amidoamine and dimethylaminopropylamine (DMAPA) rather than the betaine itself. People with a history of eyelid or scalp dermatitis are more likely to react.

An amphoteric (zwitterionic) surfactant derived from coconut oil that works well with other cleansers and is milder than anionic surfactants alone. It is widely used in gentle shampoos and body washes with a good safety profile in cosmetic use.

A glycol used very widely in Korean and Western skincare as a lightweight humectant, solvent, and gentle preservative-booster, often in place of traditional preservatives. It has a low reported irritation rate at use levels and is graded low concern in published assessments.

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 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.

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

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.

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.

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.
