Formulation view Vitamin C derivative serum using ascorbyl tetraisopalmitate for better stability than pure VC. Contains alcohol for solubility and carbomer for thickness. Suitable for brightening without high irritation. Factory observation: High alcohol content requires humectants for post-evaporation feel, and strict light-blocking packaging is needed to prevent degradation.

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
- Alcohol
- Ethanol for solubility/drying at 5-15%; high conc. is drying/irritating, avoid lip/eye, low residue, balance with humectants.
- PEG-40 Hydrogenated Castor Oil
- Solubilizer and emulsifier for oil-soluble ingredients; high concentrations may cause contact dermatitis in sensitive skin.
- Ascorbyl Tetraisopalmitate
- Vitamin C ester antioxidant; more stable than ascorbic acid but still light-sensitive.
- Hydroxyethylcellulose
- Water-soluble cellulose ether for thickening and suspension stabilization; sensitive to ions, electrolytes reduce viscosity, use at pH 7-8.
- Carbomer
- Gelling thickener requiring neutralization; watch out for ion compatibility
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Methylparaben
- Preservative, narrow spectrum; often combined, check allergen risk and regulatory limits.
