Ingredients explained
- Aqua/Water/Eau
- Water as solvent/base; main ingredient, microbial control needed, paired with preservatives.
- Alcohol Denat
- Denatured ethanol; solvent, penetration enhancer, and quick-dry agent; high % may compromise barrier in dry skin.
- Bifida Ferment Lysate
- Bifida lysate for skin conditioning; low usage, suits sensitive skin
- Ascorbyl Glucoside
- Stable Vitamin C derivative, antioxidant; more stable than pure ascorbic acid, releases activity slowly in neutral/basic conditions.
- Aminomethyl Propanol
- pH buffer at 0.1–1%; irritating at high levels, avoid direct mixing with strong acids/bases
- PEG-40 Hydrogenated Castor Oil
- Solubilizer and emulsifier for oil-soluble ingredients; high concentrations may cause contact dermatitis in sensitive skin.
- Carbomer
- Gelling thickener requiring neutralization; watch out for ion compatibility
- Mannose
- Monosaccharide humectant that binds glycosaminoglycans to enhance hydration; extremely low allergenicity
- Polysorbate 21
- Not decoded yet
- Alpha-Glucan Oligosaccharide
- Prebiotic for microflora and smoothing; use 0.5-5%, suitable for sensitive skin
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Pentylene Glycol
- Polyol humectant at 1-3%; low irritancy, suitable for sensitive skin
- Polymnia Sonchifolia Root Juice
- Jerusalem artichoke root juice, rich in polysaccharides, moisturiser; natural, prone to spoilage, needs preservatives
- Faex Extract/Yeast Extract/Extrait De Levure
- Not decoded yet
- Sodium Benzoate
- Preservative booster, effective below pH 4.5; combinable with sorbates
- Maltodextrin
- High-MW multifunctional excipient for thickening, binding, and emulsion stability; inert, non-penetrating conditioning.
- Limonene
- Natural fragrance solvent, EU allergen; poor photostability
- Geraniol
- Geraniol for fragrance; EU 26 allergen, labeling required above 0.001%.
- Hexyl Cinnamal
- Common fragrance component (jasmine/vanilla note); listed EU allergen, requires labeling at >10ppm (leave-on).
- Benzyl Benzoate
- Chelating agent for stability; restricted substance, not permitted as single component or in mixtures at ≥0.1%.
- Benzyl Alcohol
- Mild preservative/solvent at 0.5-1.0%; EU allergen (labeling required), irritation risk if concentrated, avoid in infant/highly sensitive skin.
- Lactobacillus
- Lactobacillus derivatives for skin conditioning; verify fermentation purity and safety.
- Linalool
- Natural fragrance component at ≤0.05%; one of EU 26 allergens, caution for sensitive skin
- Citral
- Citral; citrus fragrance component, listed EU allergen, high phototoxicity risk, strict concentration limits apply.
- Parfum/Fragrance
- Blended fragrance for odor; contains 26 restricted allergens, use caution in sensitive/child/eye products, verify compliance.
