Potential toxicity, not intended for human consumption, skin and eye irritation, lack of FDA/EFSA food approval

Sodium Hydroxide

Corrosive, can cause skin and eye irritation or burns upon contact, harmful if ingested or inhaled in concentrated form

Sodium Cocoyl Alaninate

Limited food safety data, potential for mild irritation if ingested in large quantities, not FDA-approved for food use

Cocamidopropyl Hydroxysultaine

Irritation, sensitization, allergic contact dermatitis

Bis-Aminopropyl Diglycol Dimaleate

Unknown for ingestion, not approved for food use, potential toxicity if ingested

Parfum/Fragrance

Irritation, sensitization, potential allergenicity, lack of ingredient transparency

Hexyl Cinnamal

Skin sensitization, allergic contact dermatitis, potential mild irritation, phototoxicity concerns at high concentrations

Limonene

Skin sensitization, allergic contact dermatitis, mild skin and eye irritation, respiratory sensitization potential, phototoxicity with oxidation products

CI 15985 / Yellow 6

Potential hyperactivity in children, allergic reactions in sensitive individuals, contaminant impurities (e.g. carcinogenic aromatic amines in some batches)

Hydrolyzed Quinoa

Ultra-processed, possible allergenicity, limited whole-food benefits

Potassium sorbate

Irritant/sensitizer in sensitive individuals, potential for minor skin and eye irritation

Polyquaternium-80

Polyquaternium-80 is a synthetic, cationic polymer commonly used in personal care products as a conditioning agent. It is not typically used in food products, and there is limited research on its ingestion. Its primary role is to improve the texture and consistency in hair and skin care formulations.
