Ingredients explained
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Hyaluronic Acid
- High-water-binding humectant at 0.1-1%; high-MW for surface film, low-MW for dermal potential, check cationic compatibility.
- Witch Hazel

- Sodium PCA
- Sodium PCA, NMF component, 1-10% humectant; salty/tacky at high levels.
- Sodium Lactate
- Sodium lactate for moisturizing and exfoliation; pH buffering agent
- 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
- Chamomile Extract

- Hydroxyethylcellulose
- Water-soluble cellulose ether for thickening and suspension stabilization; sensitive to ions, electrolytes reduce viscosity, use at pH 7-8.
- Carrageenan
- Natural thickener/gelling agent from red algae; high concentrations may cause discomfort for sensitive individuals.
- Potassium Sorbate
- Preservative effective below pH 6; combinable with sodium benzoate
- Sodium Benzoate
- Preservative booster, effective below pH 4.5; combinable with sorbates
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
