Propylene Glycol appears at position 2, indicating a high concentration. In a leave-on scalp product this is worth noting because Propylene Glycol is a chemical penetration enhancer — it can increase the absorption of co-formulated actives through the scalp, which has higher vascularisation than facial skin. Cyclopentasiloxane (D5) is a volatile silicone that ECHA has flagged for environmental persistence and potential reproductive toxicity. EU Regulation 2018/35 restricts D5 above 0.1% in rinse-off cosmetics, though the restriction has not yet been extended to leave-on products. It is a precautionary concern for regular leave-on scalp use. Amodimethicone is an amino-modified silicone with low dermal absorption and a well-characterised safety profile. The Sodium Benzoate and Potassium Sorbate dual preservative system is effective and widely used. No fragrance allergens, no parabens, no MIT, no synthetic fragrance.

The core conditioning chemistry is well-chosen. Cetrimonium Chloride is the standard cationic quaternary ammonium conditioner — it adsorbs to the negatively charged surface of damaged hair to smooth the cuticle and reduce static. Amodimethicone is an amino-modified silicone that selectively deposits on damaged sites of the hair shaft, providing heat protection and frizz control. Biotinoyl Tripeptide-1 is a biotin-peptide conjugate with evidence for hair follicle stimulation. Polyquaternium-7 adds detangling and film-forming benefit. Marine algae extracts (Hypnea Musciformis, Gelidiella Acerosa) contribute marine polysaccharide conditioning. The oil blend of Mango Seed Butter, Avocado Oil, Castor Oil, and Sunflower Seed Oil provides good emolliency. However, there are three INCI compliance errors: 'Hydrolyzed Vegetable Protein' does not specify the protein source, which is required for allergen identification; Helianthus Annuus (Sunflower) Seed Oil is listed twice (an INCI labelling error); and 'Centrimonium Chloride' and 'Cetrimonium Chloride' are the same ingredient listed twice under different spellings.

Antinorm publishes full INCI lists on its product pages. This product has three INCI compliance errors that matter for consumer transparency. First, 'Hydrolyzed Vegetable Protein' does not identify the source protein — this is required because proteins like wheat and soy are common allergens, and a consumer with a protein allergy cannot assess their risk from this label. Second, Sunflower Seed Oil (Helianthus Annuus) appears twice in the INCI, which suggests the ingredient list was not checked against a master formula before publication. Third, 'Centrimonium Chloride' and 'Cetrimonium Chloride' are the same ingredient listed twice under different spellings. For a brand that positions itself on scientific credibility, three labelling errors in a single product is a meaningful quality control gap.

No parabens and no synthetic fragrance. Plant-based conditioning oils support a reasonable sustainability profile. Cyclopentasiloxane (D5) is a persistent silicone that bioaccumulates in aquatic environments — the EU has already restricted it in rinse-off products, and a leave-on restriction may follow. No PETA certification confirmed.
