Ingredients explained

Aqua

Solvent, main base; microbial control is critical

Glycerin

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

Betaine

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

Pentylene Glycol

Polyol humectant at 1-3%; low irritancy, suitable for sensitive skin

Saccharide Isomerate

Novel polyol humectant with skin feel improvement; high hydration, suitable for lightweight formulas.

Hypnea Musciformis Extract

Brown algae polysaccharide extract; film-forming and moisturizing at 0.1–1%; add to water phase, watch allergens

Sargassum Filipendula Extract

Not decoded yet

Biosaccharide Gum-1

Biosaccharide Gum-1, fermented colloid for hydration and soothing, low comedogenic.

Panthenol

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

Hyaluronic Acid

High-water-binding humectant at 0.1-1%; high-MW for surface film, low-MW for dermal potential, check cationic compatibility.

Sodium Hyaluronate

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

Hydrolyzed Hyaluronic Acid

Low-MW humectant with superior penetration vs high-MW; 0.1-0.5% typical, hygroscopic, store dry to prevent clumping.

Glyceryl Acrylate/Acrylic Acid Copolymer

Acrylate copolymer for thickening and moisturizing; synthetic polymer with low sensitization risk.

Gelidiella Acerosa Extract

Gelidiella acerosa (seaweed) extract; complex matrix, screen for heavy metals

Silanetriol

Basic silanetriol for hair anti-static and smoothness; must be complexed with polymers for stability

Sorbitol

Polyol humectant with strong hygroscopy; tacky at high levels, pair with occlusives; also a solvent or adjuster.

Aspartic Acid

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

Alanine

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

Arginine

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

Threonine

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

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.

Geraniol

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

Valine

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

Serine

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

Proline

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

Caprylyl Glycol

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

Histidine

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

Isoleucine

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

Pca

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

Phenylalanine

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

Sodium Lactate

Sodium lactate for moisturizing and exfoliation; pH buffering agent

PEG-40 Hydrogenated Castor Oil

Solubilizer and emulsifier for oil-soluble ingredients; high concentrations may cause contact dermatitis in sensitive skin.

PPG-26-Buteth-26

Not decoded yet

Sodium Carboxymethyl Beta-Glucan

Modified glucan for thickening and cleansing aid; low irritation, suitable for most formulas

Ormenis Multicaulis Oil

Plant essential oil for fragrance and tonic effect; potential allergen, use at trace levels

Lavandula Angustifolia Oil

Fragrance essential oil, 0.1–1%; contains allergens, patch test required.

Citrus Aurantium Amara Peel Oil

Essential oil, scent regulator; III/351 allergen, labeling required.

Glycine

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

Sodium Citrate

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

Citronellol

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

Limonene

Natural fragrance solvent, EU allergen; poor photostability

Disodium EDTA

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

Citric Acid

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

Sodium PCA

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

Butylene Glycol

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

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.

Ethylhexylglycerin

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

Sorbic Acid

Preservative effective at low pH, often combined with sorbate salts; check regulatory limits
