Ingredients explained

Aqua

Solvent, main base; microbial control is critical

Dicaprylyl Ether

Lightweight diester solvent and emollient, non-greasy feel; common oil phase carrier; low irritation.

Glycerin

Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives

Hydroxyethylpiperazine Ethane Sulfonic Acid

Non-ionic buffer to adjust pH around 5.5; commonly used at 0.1–0.5%

Squalane

Emollient from plants or synthetic; light texture

Propanediol

Polyol solvent at 1–5%; light feel, aids solubilization, propylene glycol alternative

Sodium Chloride

Salt for gel viscosity control; used as precipitant in soaps

Macadamia Ternifolia Seed Oil

Macadamia oil, rich in palmitoleic, good penetration; light feel; non-comedogenic.

Betaine

Betaine for mild moisturizing/surfactant; low concentration 1-2% common, high may irritate.

3-O-Ethyl Ascorbic Acid

Water-soluble Vitamin C derivative; more stable than ascorbic acid, sensitive to metals and alkali.

Nasturtium Officinale Extract

Watercress extract, antioxidant and conditioning; 1–2% typical, fragrance allergens

Sodium Citrate

Sodium citrate for buffering and chelating; adjust pH, careful with strong acid reactions.

Sodium Hyaluronate

Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture

Sodium Hydroxide

Strong base neutralizer for pH adjustment; handle with extreme care

Helianthus Annuus Seed Oil

Sunflower seed oil for emollient/occlusive; high linoleic acid, low comedogenicity.

Gellan Gum

Gellan gum; water-soluble polymer; gel former; high transparency, strong gelling, for aqueous phase stability.

Adenosine

Skin conditioner at 0.1-1%; used for anti-aging and repair

Caprylyl Glycol

Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol

Vitreoscilla Ferment

Vitroscilla ferment, natural humectant; microbe-derived, aseptic process, low allergen risk

Citric Acid

Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH

Trisodium Ethylenediamine Disuccinate

Mild chelator replacing EDTA; water-soluble, very low irritation, stabilizes metal ions

Xanthan Gum

Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration

Ethylhexylglycerin

Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel

Tocopherol

Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light

Salicylic Acid

Lipophilic BHA at 0.5-2%; exfoliant/sebum control, irritation/sensitization at high conc., photosensitivity (SPF needed), avoid sensitive/pregnant.

Phenoxyethanol

Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin

Ci 75130

Not decoded yet

Caramel

Colorant for brown shades; some processes involve sulfites, check specs.

Ci 19140

Acid Yellow 23 lake; for coloring and hair dyeing. High water solubility and precipitation risk, pH control required.

Ci 42090

Acid Blue 9 lake; for coloring and brow tints. Non-permanent hair dye, watch for lake precipitation and batch shade variance.

Linalool

Natural fragrance component at ≤0.05%; one of EU 26 allergens, caution for sensitive skin

Limonene

Natural fragrance solvent, EU allergen; poor photostability

Citral

Citral; citrus fragrance component, listed EU allergen, high phototoxicity risk, strict concentration limits apply.

Citronellol

Citronellol for fragrance; EU 26 allergen, labeling required above 0.001%.

Parfum

Fragrance for scent; may contain allergens, caution for sensitive skin, full labeling required.
