Ingredients explained

Water

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

Butylene Glycol

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

Glycerine

Workhorse humectant at 3-10%; tacky at high levels, pair with occlusives, low irritancy.

Saccharide Isomerate

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

Panthenol

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

Sodium Hyaluronate

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

Phenoxyethanol

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

Sodium Lactate

Sodium lactate for moisturizing and exfoliation; pH buffering agent

Sodium PCA

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

Ammonium Acryloyldimethyltaurate/VP Copolymer

Cationic polymer providing suspension, thickening, and conditioning; often paired with anionic thickening systems, low usage, imparts slip.

Arginine

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

Chlorphenesin

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

Aspartic Acid

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

Disodium EDTA

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

Dipotassium Glycyrrhizate

Dipotassium glycyrrhizinate for moisturizing/soothing; inhibits 5-LOX, water-soluble, for sensitive skin.

Pca

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

PEG-40 Hydrogenated Castor Oil

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

Citric Acid

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

PEG-60 Hydrogenated Castor Oil

Non-ionic emulsifier and solubilizer at 1–5%; contains PEG, check acid compatibility and sensitive skin irritation

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

Biosaccharide Gum-1

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

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.

Saccharomyces/Iron Ferment

Ferment rich in minerals and bioactives for skin conditioning.

Saccharomyces/Silicon Ferment

Yeast-silicon ferment with minerals for skin conditioning; check micro limits

Saccharomyces/Copper Ferment

Ferment filtrate used as a skin conditioning agent

Saccharomyces/Zinc Ferment

Yeast ferment for anti-dandruff and skin conditioning; limited to III/24h, avoid with high acid levels

Saccharomyces/Magnesium Ferment

Yeast and magnesium ferment supplementing minerals and peptides; functional co-agent, typically low concentration

Phenylalanine

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

Histidine

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

Rosa Canina Fruit Oil

Rosehip oil, rich in oleic/linoleic acids for emolliency/repair; prone to oxidation, needs protection

Prunus Armeniaca Kernel Oil

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

Persea Gratissima Oil

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

Caprylyl Glycol

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

Sodium Carboxymethyl Beta-Glucan

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

1-2-Hexanediol

Not decoded yet

Honey Extract

Humectant and skin conditioning agent; hygroscopic, sensitive to pH.

Helianthus Annuus Seed Oil

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

Natto Gum

Natto gum, film-forming; 0.1–0.5% typical, low irritation, low sensitization
