Ingredients explained

Aqua

Solvent, main base; microbial control is critical

Glycerin

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

Alcohol Denat

Denatured ethanol; solvent, penetration enhancer, and quick-dry agent; high % may compromise barrier in dry skin.

Dimethicone

Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin

Hydroxyethylpiperazine Ethane Sulfonic Acid

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

Prunus Armeniaca Kernel Oil

Plant oil for emollience and nutrition; contains proteins that may cause sensitivity, use caution in sensitive skin

Hydroxyethyl Urea

Potent humectant and conditioner; high penetration, used for skin hydration and hair care

Butyrospermum Parkii Butter

Shea butter for occlusive moisturizing; high melt point, rich texture, caution for oily skin.

Nasturtium Officinale Extract

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

C12-13 Pareth-23

Not decoded yet

C12-13 Pareth-3

Not decoded yet

Ceramide NP

Ceramide N3 for barrier repair; lipophilic, needs oil phase or emulsion, avoid high standalone use.

Carbomer

Gelling thickener requiring neutralization; watch out for ion compatibility

Zinc Gluconate

Chelated zinc salt with antimicrobial and deodorizing effects; used in antiperspirants and oral care; has EU concentration limit.

Glycine Soja Oil

Soybean oil emollient; prone to oxidation, needs antioxidants; suitable for dry skin

Sodium Chloride

Salt for gel viscosity control; used as precipitant in soaps

Sodium Hydroxide

Strong base neutralizer for pH adjustment; handle with extreme care

Divinyldimethicone/Dimethicone Copolymer

Silicone copolymer for slip and film; occlusive with smooth texture

2-Oleamido-1,3-Octadecanediol

Lipid-based emollient for barrier repair; lipophilic.

Cholesterol

Cholesterol; barrier repair lipid mimicking stratum corneum; often blended with ceramides, plant or fermentation source.

Ammonium Polyacryloyldimethyl Taurate

Cationic water-soluble polymer; stabilizer and conditioner, test compatibility with anions

Disodium EDTA

Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy

Hydroxypalmitoyl Sphinganine

Not decoded yet

Capryloyl Salicylic Acid

Oil-soluble salicylic acid derivative for gentle pore unclogging; milder than BHA, suitable for daily acne care.

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

Xanthan Gum

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

Menthoxypropanediol

Menthol derivative; cooling agent for immediate freshness; concentration control to avoid irritation.

Ethylhexylglycerin

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

BHT

Lipophilic antioxidant at 0.01-0.05%; ineffective with acidic systems, label-sensitive, check regulatory limits as preservative alternative.

Tocopherol

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

Tocopheryl Acetate

Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light

Phenoxyethanol

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

Chlorphenesin

Phenolic antimicrobial; strict EU limits apply, potential allergen, careful dosing required for leave-on products.

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.

Parfum

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