Ingredients explained

Water

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

Glycerin

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

Sodium Polyacrylate

Superabsorbent resin, <1%; gels with electrolytes, ionic strength control required.

Sodium PCA

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

Aloe Barbadensis Leaf Juice

Natural humectant and soother with high water activity; requires preservative system, generally well-tolerated

Sodium Lactate

Sodium lactate for moisturizing and exfoliation; pH buffering agent

Gluconolactone

Multifunctional agent for chelation and permeation; acidic, may irritate at high levels, buffer recommended.

Sodium Hyaluronate

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

Wheat amino acids

Wheat amino acids for hair/skin; contains gluten, allergy caution

Triticum Vulgare Germ Extract

Wheat germ extract, nutrient-rich; contains gluten, test for sensitivity.

Sodium Benzoate

Preservative booster, effective below pH 4.5; combinable with sorbates

Symphytum Officinale Leaf Extract

Panthenol

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

Saccharomyces Lysate Extract

Yeast lysate humectant and conditioner; rich in amino acids and NMF, strong barrier repair

Hydroxyproline

Amino acid derivative for humectancy and skin conditioning; supports collagen metabolism, water-soluble, gentle

Urea

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

Niacinamide

Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity

Inositol

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

Glycine

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

Fructose

Strong humectant; high levels can increase viscosity and hygroscopicity.
