Anionic surfactants, nonionic surfactants and amphoteric surfactants are the main ones with decontamination effects. It is a combination of its penetration, emulsification and dispersion, solubilization, foaming and other effects. It is generally used in skin cleansing and bathing products.
Common stain removers
| Chemical Name | Trade Name | Characteristic | Main Features |
| Sodium dodecyl sulfate | K12 | White or slightly yellow powder or liquid | Good water solubility, strong detergency, good foaming, emulsification performance is not affected by pH, good biodegradability. Highly irritating, also commonly used as emulsifier |
| Triethanolamine dodecyl sulfate | LST | Light yellow transparent viscous liquid | Mild in nature, lower degreasing and stinging properties than K12, and good compatibility with anionic surfactants. It has thickening effect. It is often used as the main detergent of shampoo and bath, and also used as emulsifier. |
| Fatty alcohol polyoxyethylene ether sulfate | AES | Light yellow viscous liquid | Good detergency in hard water. Good heat resistance, very low irritation, good compatibility with other anionic and nonionic surfactants |
| Alcohol ether sulfosuccinate disodium salt | MES | Light yellow viscous transparent liquid | It is the least irritating and mildest surfactant species, with strong foaming power and good detergency, and can be compounded with cationic surfactants to form a two-in-one shampoo at low cost. However, its viscosity characteristics are poor and its product viscosity is difficult to adjust. |
| Straight chain alkyl benzene sulfonate | LAS、ABS | Strong detergency and good foaming and solubility, wide source and low price | |
| Sodium secondary chain alkyl sulfonate | SAS | Light yellow liquid or solid | Excellent biodegradability, good detergency and emulsifying power High solubility |
| Alkenyl sulfonate | AOS | Good detergency and foaming power in hard water, good biodegradability. Low irritation to skin. Its product is a mixture, product quality is not well controlled and production is limited | |
| N-yl glutamate | AGA | Milky white or light yellow powder | Good washing power and detergency. Hard water resistance, affinity for hair, small skin prickly dispersion can be used with a variety of surfactants, and has a certain degree of bactericidal ability |
| Sodium oleoyl amino acid | Lamepon A 613 detergent | Brownish yellow viscous liquid | Good stability in alkaline or neutral solutions, good detergency and emulsification ability in alkaline media, low irritation to the skin, mild, can give hair good conditioning, hard water resistance |
| Sodium N-oleoyl-N-methyl taurate | Igepon T 209 detergent | Milky white or light yellow liquid | Good detergency and emulsification performance Good foam performance, hard water resistant. Good compatibility and biodegradability. Higher cost |
| Tea Saponin | Light yellow powder | Natural surfactant, with strong foaming and decontamination power and emulsification and dispersion properties, low irritation to human body, safe, anti-inflammatory, antiseptic, anti-itch and anti-dandruff, good biodegradability |
| Dodecyl dimethyl betaine | BS-12 | Colorless or slightly yellow viscous liquid | In any pH value can be dissolved in water to form a transparent liquid, its aqueous solution has strong detergency, good foaming power and permeability, good anti-hard water and biodegradability, low irritation, mild nature and good compatibility, with conditioning, anti-static, softness and sterilization ability |
| Cocamidopropyl betaine | BS-12K | Slightly yellow transparent liquid | Milder, easily soluble in water with excellent decontamination, softness, anti-static, foaming and thickening ability, also has antibacterial and conditioning properties, low irritation to the skin, easy biodegradability, can replace BS-12 |
| Carboxylate-type imidazoline | DCM | Carboxylate-type imidazoline | Mild nature, washing power, strong foaming power, minimal irritation to skin. Good biodegradability, easily soluble in water. Good compatibility, good hard water resistance, emulsifying, anti-static, softening effect |
| Fatty alcohol polyoxyethylene ether | AEO (Ping Ping Plus) | – | Good detergency and decontamination ability, with different properties depending on the number of ethylene oxide addition |
| Alkylphenol polyoxyethylene ether | APE | – | Good water solubility, poor biodegradability |
| Polyether | – | Can be used as low-foaming detergent, emulsifier, good safety, low toxicity |
