The following is the detailed research of our Suave Shampoo Proof Process.

Suave Daily Clarifying Shampoo: Water, Ammonium Lauryl Sulfate, Ammonium Laureth Sulfate, Cocamide MEA, Ammonium Chloride, PEG-5 Cocamide, Cocamidopropyl Betaine, Fragrance (Parfum), Hydroxypropyl Methylcellulose, Tetrasodium EDTA, DMDM Hydantoin, Citric Acid, Dimethicone Copolyol, Methylchloroisothiazolinone, Methylisothiazolinone, Tocopheryl Acetate (Vitamin E Acetate), Blue 1 (Cl 42090), Red 33 (Cl 17200), Ext. Violet 2 (Cl 60730)

Water: no health or environmental concern.

Ammonium Lauryl Sulfate & Ammonium Laureth Sulfate: cause irritation to eyes, skin and respiratory system if ingested or inhaled.[1][2]

Cocamide MEA: is a compound synthesized from coconut oils and ethanolamine. Safe as a rinse off product when concentrated at 10% or lower. However, it can be toxic if inhaled.[3]

Ammonium Chloride: can cause irritation when inhaled or when it makes eye contact.[4]

PEG-5 Cocamide: a Polyethylene Glycol amide of Cocos Nucifera (Coconut) Acid, in which the fatty acids are derived from coconut oil. PEG-5 Cocamide can contain harmful impurities, including: Ethylene Oxide, known to increase the incidences of uterine and breast cancers and of leukemia and brain cancer, according to experimental results reported by the National Toxicology Program; 1,4-dioxane, a known carcinogen; and PAHs, known to increase the risk of breast cancer; lead; iron; and arsenic. Products and formulas containing PEGs should not be used on broken or irritated skin.[5]

Cocamidopropyl Betaine: is a synthetic surfactant; and has been associated with irritation and allergic contact dermatitis.[6]

Fragrance: is a trade secret the exact process and ingredients are unknown.

Hydroxypropyl Methylcellulose: is a semi synthetic polymer based on cellulose- non toxic.[7]

Tetrasodium ETDA: is a polyamino carboxylic acid tetrasodium salt synthesised from ethylenediamine, formaldehyde and sodium cyanide. Ethylenediamine is a skin irritant.[8] Sodium cyanide is a poison.[9] Formaldehyde is highly toxic and fatal at as little as 30mL of a solution containg 37% formaldehyde.[10]

DMDM Hydantoin: is a strong skin allergen and toxicant. It is a preservative that works by releasing formaldehyde into the shampoo.[11][12]

Citric Acid: no health or environmental concerns.

Dimethicone Copolyol: a silicon-based polymer used as a lubricant and conditioning agent. Safe because it doesn’t penetrate past the skin.[13]

Methylchloroisothiazolinone: is a preservative with antibacterial and antifungal effects. In pure form or in high concentrations, it can be a skin and membrane irritant or cause chemical burns. It was largely removed from most cosmetic products except for those with only short duration skin contact such as rinse-offs.[14]

Methylisothiazolinone: is a skin irritant and toxicant.[15][16]

Tocopheryl Acetate: is an ester of acetic acid and tocopherol. Acetic acid is corrosive and is a skin toxicant and irritant and causes allergic reaction. It is not oxidized which means it can penetrate through the skin to living cells.[17]

Blue 1: produced from petroleum and may be toxic to humans. There is a lack of research related to the health effects of Blue 1.[18]

Red 33: produced from petroleum and is not expected to be harmful. There is a lack of research related to the health effects of Blue 1.[19]

Ext. Violet 2: is produced from coal tar which is a known carcinogen. Violet 2 is an eye irritant and can cause be a skin irritant.[20][21]
