Formulation view Shampoo built on a sulfate backbone (SLES/SLS) with coco-betaine for gentle cleansing, thickened with sodium chloride. Includes salicylic acid, zinc PCA, and biotin for scalp oil control. Uses MIT/CMIT preservatives. Suitable for oily scalps. A formulator notes the high-surfactant system requires careful pH adjustment and thickening for stability, warranting caution for sensitive heads.

Ingredients explained
- Aqua/Water/Eau
- Water as solvent/base; main ingredient, microbial control needed, paired with preservatives.
- Sodium Laureth Sulfate
- Common anionic surfactant, strong foam but drying; check cationic compatibility, high eye irritation
- Sodium Lauryl Sulfate
- Strong anionic surfactant, high foam; high irritation risk, avoid in sensitive formulas.
- Coco-Betaine
- Mild amphoteric cleanser, good foam; may precipitate with cationics, control dose for low irritation
- Hexylene Glycol
- Polyol solvent and humectant with penetration enhancement; limit concentration to avoid irritation, no specific allergen tag
- Sodium Chloride
- Salt for gel viscosity control; used as precipitant in soaps
- Parfum/Fragrance
- Blended fragrance for odor; contains 26 restricted allergens, use caution in sensitive/child/eye products, verify compliance.
- Glycol Distearate
- Glycol distearate for thickening and emulsification; non-ionic, improves viscosity
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
- Alcohol Denat
- Denatured ethanol; solvent, penetration enhancer, and quick-dry agent; high % may compromise barrier in dry skin.
- Polyquaternium-30
- Not decoded yet
- Hydroxypropyl Guar Hydroxypropyltrimonium Chloride
- Cationic guar derivative, conditioner/antistatic; hair/cutaneous use, watch concentration.
- Carbomer
- Gelling thickener requiring neutralization; watch out for ion compatibility
- Limonene
- Natural fragrance solvent, EU allergen; poor photostability
- Hexyl Cinnamal
- Common fragrance component (jasmine/vanilla note); listed EU allergen, requires labeling at >10ppm (leave-on).
- Coumarin
- Classic fragrance and photosensitizer, EU restriction III/77; high allergen risk, limit in facial products
- Benzyl Alcohol
- Mild preservative/solvent at 0.5-1.0%; EU allergen (labeling required), irritation risk if concentrated, avoid in infant/highly sensitive skin.
- Magnesium Nitrate
- Inorganic salt for hair conditioning; improves smoothness and shine, high concentrations may stiffen hair, balance cationics.
- Linalool
- Natural fragrance component at ≤0.05%; one of EU 26 allergens, caution for sensitive skin
- Salicylic Acid
- Lipophilic BHA at 0.5-2%; exfoliant/sebum control, irritation/sensitization at high conc., photosensitivity (SPF needed), avoid sensitive/pregnant.
- Amyl Cinnamal
- Fragrance ingredient restricted in the EU; usage limits apply to minimize allergic contact dermatitis risk.
- Zinc Pca
- Zinc salt for sebum control and antimicrobial; often paired with PCA sodium, high levels may cause sensitization
- Biotin
- Vitamin B7 nutrient claimant; topical effect limited, use at 1-20 ppm.
- Safflower Glucoside
- Nonionic surfactant for hair conditioning; improves slip and shine in rinse-off formulas; check cationic compatibility.
- Geraniol
- Geraniol for fragrance; EU 26 allergen, labeling required above 0.001%.
- Isoeugenol
- Isoeugenol flavor/perfume, EU limit III/73; moderate allergen, total concentration <0.01%
- Alpha-Isomethyl Ionone
- Vanilla-like fragrance ingredient; one of EU 26 allergens, caution advised for sensitive skin.
- Methylchloroisothiazolinone
- Preservative (MCI); highly sensitizing, use only in rinse-off, avoid leave-on products.
- Magnesium Chloride
- Inorganic salt for thickening and pH adjustment; 0.1-1%, avoid calcium ions
- Methylisothiazolinone
- Strong preservative; high allergy risk, EU restricted for leave-on products, high formulation risk
- Tocopherol
- Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light
- Sodium Citrate
- Sodium citrate for buffering and chelating; adjust pH, careful with strong acid reactions.
