It is a kind of white or yellowish-yellow slime and is often used in detergents and textile industries in industry.Anionic surfactant.Soluble in water, with anionic and non-ionic complex compatibility is good, good emulsification, foaming, osmosis, decontamination and dispersion properties, are widely used in toothpaste, shampoo, shampoo, shampoo, detergent, liquid washing, cosmetics and plastic mold release, lubrication and pharmaceutical, paper making, building materials, chemical industry, etc.
[use 1] used as detergent and textile auxiliaries, also used as toothpaste foaming agent, mine fire extinguishing agent, emulsion polymerization emulsifier, wool cleaning agent, etc.
[use 2] as anionic surface active agent, emulsifier and foaming agent.
[use 3] GB 2760-96 is used as a processing aid for food industry.Foaming agent;Emulsifier;Anionic surfactant.Used for cake, beverage, protein, fresh fruit, fruit juice beverage, edible oil, etc.
[use 4] as an emulsifier for drugs, cosmetics and synthetic resins.The foaming agent of toothpaste and fire extinguisher.Used as a detergent for fine fabrics of silk and wool.Flotation agent for metallic ore dressing.
[use 5]Used for washing and textile auxiliaries, foaming agent, also used as toothpaste foam liquid, emulsion polymerization emulsifier, medical use emulsifying dispersant, shampoo and other makeup products, wool cleaner.
[use 6] biochemical analysis, electrophoresis, ion pair reagent.
Sodium dodecyl sulfate is a kind of common ionic type detergent, can make the cell membrane disruption, combined with membrane protein hydrophobic part and make it with membrane separation, high concentrations of SDS can also break down the ionic bonding and hydrogen bonding and other non covalent bonds in proteins, even change the conformation of proteins.This characteristic is often used in the SDS gel electrophoresis of protein composition analysis.
Acute toxicity: LD50:2000 mg/kg (mouse via mouth);1288 mg/kg (rat via mouth)
Irritation: irritation to the respiratory tract.
Health hazard: stimulation of mucous membrane and upper respiratory tract, stimulating effect on eyes and skin.Can cause the respiratory system allergic reaction.
Ignition hazard: this product is flammable, stimulating and sensitive.In case of open fire and high heat.A poisonous gas is released by high thermal decomposition.
Harmful combustion products: carbon monoxide, carbon dioxide, sulfide, sodium oxide.
Degreasing ability of surfactants, so often been used in the cleanser, due to a strong cleaning ability and high stimulating long-term use can seriously reduce the defense capability of the skin, causing skin cell development is not mature, loose structure, make the skin layer thinning vulnerable to external stimuli and cutin alienation, vulnerable, pore bulky, color of skin dark heavy, blain blain is breeding, aging and a series of questions!
Skin contact: remove contaminated clothing and flush with plenty of flowing water.
Eye contact: lift eyelid and rinse with flowing water or saline.Go to a doctor.
Inhalation: remove from site to fresh air.If breathing is difficult, give oxygen.Go to a doctor.
Food intake: drink plenty of warm water and vomit.Go to a doctor.
Fire extinguishing method: the fireman should wear a gas mask, wear a full-body fire suit, and put out the fire in the wind direction.Extinguishing agent: fog water, foam, dry powder, carbon dioxide, sand.
Leakage emergency treatment:
Emergency treatment: isolate the contaminated area and limit access.Cut off the fire.It is recommended that emergency treatment personnel wear dust mask (full cover) and wear protective clothing.Avoid dust, carefully sweep, and transfer to safety in the bag.If a lot of leakage, use plastic cloth, canvas cover.Collection or transport to waste disposal sites.
