Ingredients explained

Aqua

Solvent, main base; microbial control is critical

Glyceryl Glucoside

Polyol humectant with light, non-sticky feel; less tacky than glycerin

Panthenol

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

Glycerin

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

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.

Urea

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

Creatine

Skin conditioning agent for moisturizing and anti-aging; used at low concentrations, generally well-tolerated by sensitive skin.

Allantoin

Skin soother at 0.5-2%; promotes cell regeneration

Diglycerin

Diglycerin humectant and conditioner; low viscosity suitable for liquid formulas, very low irritancy.

Amelanchier Alnifolia Fruit Extract

Amelanchier alnifolia fruit extract. Used for antioxidant and skin conditioning purposes. Natural source, monitor for potential allergenicity.

Propylene Glycol

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

Daucus Carota Sativa Juice

Not decoded yet

Lactic Acid

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

Hydrolyzed Wheat Protein

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

Lysine

Amino acid conditioner for anti-static hair care; low irritation at typical cosmetic concentrations.

Pca

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

Sorbitol

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

Trehalose

Trehalose; mild humectant and stabilizer for proteins/actives; hygroscopic, light skin feel.

Calcium Pantothenate

Pro-vitamin B5 for hair/skin conditioning; water-soluble, used in conditioners

Ethylhexylglycerin

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

Hydroxyacetophenone

Hydroxyacetophenone as antioxidant; often boosts Vitamin C, works in acidic pH.

Acetyl Glucosamine

Glycosaminoglycan precursor supporting skin hydration and elasticity; highly biocompatible.

Taurine

Taurine; buffering and chelating. Common in shampoos and eye washes, water-soluble.

Glycine Soja Seed Extract

Soybean extract for skin conditioning; low allergen risk, monitor batch protein variability.

Phenoxyethanol

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

Lysine Hcl

Lysine HCl, amino acid for hair and skin conditioning, reduces protein loss

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.

Histidine Hcl

Amino acid salt for pH buffering and hair conditioning; gentle buffering system, potential sensitization at high concentrations.

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.

Glutamic Acid

Glutamic acid, non-essential amino acid humectant; high levels can be astringent, buffer needed.

Threonine

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

Valine

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

Leucine

Amino acid for antistatic and skin/hair conditioning; used at low concentrations.

Glycine

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

Isoleucine

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

Phenylalanine

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

Potassium Sorbate

Preservative effective below pH 6; combinable with sodium benzoate

Sodium Benzoate

Preservative booster, effective below pH 4.5; combinable with sorbates

Citric Acid

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