Ingredients explained
- Deionized Water
- Deionized water as primary solvent; inactive but carries other ingredients, purity needed to prevent metal ion interference.
- Carbomer
- Gelling thickener requiring neutralization; watch out for ion compatibility
- Glycolic Acid
- Glycolic acid for exfoliation; requires buffering at concentrations >10%, avoid combination with other acids.
- Azelaic Acid
- Acne and pigment agent; 15-20% can be irritating, needs controlled release or lower doses.
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- EDTA
- Chelating agent for stability; use metal salts, keep concentration low (<0.1%) to maintain pH.
- Potassium Sorbate
- Preservative effective below pH 6; combinable with sodium benzoate
