Classic Clean Anti-Dandruff Conditioner

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

A fatty alcohol derived from stearic acid that thickens creams and gives them a smooth, non-greasy glide. It is one of the fatty alcohols the CIR panel reviewed together and found safe as used, with a very low reported rate of contact sensitization.

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

A cationic conditioning agent used in rinse-off products like shampoos and conditioners to provide softness and detangling. Generally well tolerated but can cause irritation at high concentrations in some individuals.

An amino acid widely used in cosmetics for skin conditioning and moisture retention. It is well-studied and well-tolerated across skin types at cosmetic use levels.

The active anti-dandruff ingredient in medicated shampoos, used at 1% or 2% to reduce Malassezia yeast and flaking. It is well studied and considered safe in rinse-off use; EU rules cap leave-on hair products because it is more irritating with prolonged skin contact, which is why it is formulated into shampoos meant to be rinsed out.

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

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

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.

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

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 jasmine-like fragrance compound frequently used in soaps and lotions. It is one of the 26 EU-designated fragrance allergens, though studies suggest its sensitization potency is comparatively low relative to other listed allergens.

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

Methylchloroisothiazolinone is typically used together with methylisothiazolinone in a 3:1 mix and is a well-documented skin sensitizer at higher rates than most preservatives. EU rules now restrict this combination to rinse-off products only, at a low maximum concentration.

A preservative that caused a wave of contact allergy in the 2010s. The EU banned it from leave-on products and tightly limits it in rinse-off ones. A genuine concern, not a myth.
