Ingredients explained

Aqua

Solvent, main base; microbial control is critical

Cocamidopropyl Hydroxysultaine

Mild amino acid amphoteric surfactant for cleansing and foam boosting; low irritation, biodegradable

Polyacrylate Crosspolymer-6

Water-soluble thickener; requires neutralizer, performs best at pH 5–7

Butylene Glycol

Polyol humectant and solvent at 1–5%; aids solubilization, light feel

Caffeine

Active ingredient, 0.1–2%; promotes circulation, irritation risk at high concentration.

Dimethyl Sulfone

Dimethyl sulfoxide, strong penetrant and solvent; volatile odor, concentration control needed

Lactobacillus/Eriodictyon Californicum Ferment Extract

Ferment extract for antioxidant and repair benefits; verify active stability

Sodium Chloride

Salt for gel viscosity control; used as precipitant in soaps

Cetyl Betaine

Amphoteric surfactant, mild foam boosting and conditioning; improves foam stability, minimal irritation to hair and skin.

Coffea Arabica Seed Extract

Coffee extract for skin conditioning/antioxidants; contains caffeine, watch sensitivity.

Lauryl Betaine

Mild amphoteric surfactant; foaming and stabilizing. Eye irritation may exceed anionics, use low levels for sensitive skin.

Acetyl Cysteine

Cysteine derivative antioxidant and conditioner; check pH and metal ion compatibility.

Acetyl Methionine

Acetyl methionine; skin conditioning and nutritional support; typically low concentration, check compatibility

Inositol

Humectant at 0.5–2%; gentle moisturizing, suitable for sensitive skin

Arginine

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

Aspartic Acid

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

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.

Histidine

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

Phenylalanine

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

Biotin

Vitamin B7 nutrient claimant; topical effect limited, use at 1-20 ppm.

Creatine Monohydrate

Sodium Pca

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

Pca

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

Sodium Lactate

Sodium lactate for moisturizing and exfoliation; pH buffering agent

Lactic Acid

AHA pH adjuster at 0.5-5%; exfoliation/humectancy, mild at low conc., irritating at high, avoid conflict with alkaline preservatives.

Lactose

Low-irritant humectant and skin conditioner, common in gentle formulations.

Urea

Potent humectant and keratolytic, >10% has exfoliating effect; stinging sensation at high levels, sensitive skin caution

Milk Protein

Not decoded yet

Hydrolyzed Wheat Protein

Hydrolyzed protein for hair and skin conditioning; potential allergen, use low levels in sensitive products

Arctium Lappa Root Extract

Burdock root extract for skin conditioning; watch for raw material impurities.

Eugenia Caryophyllus Flower Extract

Clove flower extract containing eugenol (allergen); astringent and antimicrobial properties; high concentrations may irritate oral mucosa.

Origanum Vulgare Leaf Extract

Oregano extract with antimicrobial properties; high doses may irritate.

Barosma Betulina Leaf Extract

Barosma betulina leaf extract, botanical soother and fragrance

Propanediol

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

Glycerin

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

Phospholipids

Biomimetic repair and emollient, mimics skin lipids; typically processed at low temps, may be sticky at high levels

Lecithin

Phospholipid emulsifier at 1-5%; biocompatible, moisturizing/antioxidant, prone to oxidation (add TBHQ), mild for sensitive skin.

Citric Acid

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

Sodium Citrate

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

Disodium Phosphate

Phosphate buffer for pH adjustment and preservation; water-soluble; high levels may irritate mucous membranes.

Diethyl Phthalate

Not decoded yet

Propylene Glycol

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

Alcohol Denatured

Denatured alcohol for solvency and penetration; causes dryness, use caution in sensitive skin.

Leuconostoc/Radish Root Ferment Filtrate

Bio-fermented filtrate for antimicrobial and anti-dandruff effects; assess individual variability, avoid in known allergy.

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
