Ingredients explained

Water

Primary solvent and base; requires preservative system to prevent microbial growth

Dimethicone

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

Cetyl Alcohol

Cetyl alcohol for emulsification/thickening; high concentration >10% may irritate.

Persea Gratissima Oil

Avocado oil rich in fatty acids and vitamin E; occlusive moisturizer, use with caution on oily skin.

Glycerin

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

Stearyl Alcohol

Stearic alcohol; fatty alcohol for emulsion thickening/structure, often blended with soaps, moderate comedogenicity.

Ethylhexyl Olive Grove

Olive-based derivative for conditioning; natural source, requires stability and allergen assessment.

Behentrimonium Chloride

Cationic conditioner and preservative; used within restricted limits, high doses may irritate.

Cetrimonium Bromide

Cationic surfactant/preservative for hair products; antistatic, emulsifying, cleansing. Restricted in EU to 0.1% ocular. Incompatible with anionics.

Limnanthes Alba Seed Oil

Lightweight natural oil with mineral oil-like feel; oxidizes easily, add antioxidants and control dose.

Oryza Sativa Bran Oil

Rice bran oil rich in oryzanol and linoleic acid for conditioning; moderate comedogenic rating, mind oxidative stability.

Quaternium-80

Not decoded yet

Sodium Hyaluronate

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

Sodium PCA

Sodium PCA, NMF component, 1-10% humectant; salty/tacky at high levels.

Ceramide AP

Ceramide analog for barrier repair; best results when combined with cholesterol and free fatty acids

Ceramide NP

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

Bis-Aminopropyl Diglycol Dimaleate

Bis-aminopropyl diglycol dimaleate, hair conditioner; cationic conditioner for post-perm care, control concentration.

Cannabis Sativa Seed Oil

Hemp seed oil, non-psychoactive, emollient for skin and hair; high linoleic acid, needs antioxidants

Rosa Canina Seed

Dog rose seeds used as physical exfoliant; note abrasive nature for sensitive skin.

Hydrolyzed Jojoba Esters

Lightweight emollient and film-former; improves hair slip, generally low concentration.

Arginine

Arginine for moisturizing/conditioning; amino acid, high biocompatibility, often used in blends.

Jojoba Esters

Jojoba esters, light emollient ester, low comedogenic; sebum-like, excellent spreadability.

Panthenol

Panthenol (vitamin B5) at 1–5%; moisturizing and reparative, supports barrier recovery

Squalane

Emollient from plants or synthetic; light texture

Carthamus Tinctorius Seed Oil

Natural seed oil rich in linoleic acid; moisturizing, prone to oxidation, needs antioxidants

Glycine

Humectant amino acid, 1–3%; small molecule, low irritation.

Alanine

Amino acid for antistatic and conditioning; low irritation, slight salty taste at high levels

Serine

Humectant amino acid, 1–3%; high water solubility, compatible with sensitive skin.

Valine

Amino acid humectant, common in amino acid cleansers and sprays; mild, suitable for all skin types

Isoleucine

Amino acid for hair and skin conditioning and antistatic purposes; often blended; check taste if high.

Proline

Proline, amino-acid humectant; boosts stratum corneum hydration, stable at pH 4-5.

Threonine

Threonine, essential amino acid for hair/skin; blended with other AAs for balance.

Guar Hydroxypropyltrimonium Chloride

Cationic guar derivative for antistatic, film-forming, viscosity control; common in hair/skin conditioning

Histidine

Amino acid humectant and antistatic agent; pH-dependent behavior, consider buffering in formulation.

Hydroxyethylcellulose

Water-soluble cellulose ether for thickening and suspension stabilization; sensitive to ions, electrolytes reduce viscosity, use at pH 7-8.

Phenylalanine

Amino acid for hair and skin conditioning; usually part of a blend, no significant standalone efficacy data

Aspartic Acid

Amino acid humectant and conditioner, common in rinse-off products; low levels mild, high levels may shift pH

Pca

Proline carboxylic acid, NMF component; humectant, generally low irritation but may sensitise.

Phosphatidylcholine

Biocompatible emulsifier mimicking sebum; plant/egg derived, check oxidative stability

Citric Acid

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

Sodium Lactate

Sodium lactate for moisturizing and exfoliation; pH buffering agent

Propylene Glycol

Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.

Isopropyl Alcohol

Alcohol solvent at 1–10%; fast-evaporating, high levels may cause dryness/irritation

Sodium Nitrate

Milding agent mainly in oral care (mouthwash/toothpaste); rare in cosmetics.

Tocopherol

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

Ethylhexylglycerin

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

Sodium Benzoate

Preservative booster, effective below pH 4.5; combinable with sorbates

Phenoxyethanol

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

Bis-Cetearyl Amodimethicone

Diamodimethicone derivative for hair conditioning; low allergen, works with cationic polymers.

Fragrance

Fragrance; concentration must control allergen risk, label specific components

Citral

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

Hexyl Cinnamal

Common fragrance component (jasmine/vanilla note); listed EU allergen, requires labeling at >10ppm (leave-on).

Limonene

Natural fragrance solvent, EU allergen; poor photostability
