- Potassium Hydroxide
- Citric Acid
- Disodium EDTA
- Chlorphenesin
- Phenoxyethanol
Answer
Based on the ingredient list provided, the following ingredients are negatively charged (anionic) or become negatively charged in the formulation:
- Carbomer: This is a polymer that becomes negatively charged when neutralized by a base (like Potassium Hydroxide, which is also in the list).
- Glyceryl Acrylate/Acrylic Acid Copolymer: This copolymer contains acrylic acid groups that become negatively charged when neutralized.
- TEA-Cocoyl Glutamate: This is an anionic surfactant.
- Disodium EDTA: This is a salt of EDTA, which is a negatively charged chelating agent.
- Citric Acid: This is an acid that carries negative charges depending on the pH of the formulation.
