Chemical Structure
Basic Info
Sodium dodecyl sulfate is a typically made use of pharmaceutical excipient, which is an anionic surfactant that can be utilized as a solubilizer, emulsifier, skin passing through agent, lubricating substance for tablets and capsules, wetting representative, etc. Salt dodecyl sulfate is a frequently used emulsifier in solutions, made use of to prepare O/W emulsion matrices.
The HLB value of Salt dodecyl sulfate is about 40, and the generally utilized dosage is 5-20 g · L-1. However, excessive dosage has little result on lowering surface area stress.
Often made use of in combination with other W/O emulsifiers (such as monoglycerides, fatty acid sorbitan, etc) to adjust the HLB value of the lotion system, the emulsification result is better. The salt dodecyl sulfonate additionally advertises the graft response in between starch and monomer, hence boosting the attachment and stability of starch cream.

Product Packaging
Sodium Lauryl Sulfate (SLS) is a common anionic surfactant widely used in personal care products, household cleaners, and industrial cleaners. Due to its excellent foaming, cleaning, and emulsifying properties, Sodium dodecyl sulfate is widely used in daily products such as shampoo, toothpaste, and facial cleanser. However, its use has also sparked some controversies such as skin sensitivity. The following will provide a detailed introduction to the chemical properties, applications, and precautions to be taken during the use of SLS.
1、 Chemical properties of sodium dodecyl sulfate
Sodium dodecyl sulfate is a salt obtained by sulfating dodecyl alcohol (also known as lauryl alcohol) and neutralizing it with sodium hydroxide or sodium carbonate. Its molecular structure contains a hydrophobic group (alkyl chain) with a twelve carbon chain and a hydrophilic group (sulfate ester group), which endows Sodium dodecyl sulfate with strong cleaning, foaming, and emulsifying abilities.
Sodium dodecyl sulfate has good water solubility and is stable in a wide range of pH values, and can produce rich foam in water. It not only effectively removes oil and dirt from the skin and surface of objects, but also enhances the texture of the product in the formula, providing a better user experience. However, due to its strong surface activity, SLS has a strong ability to remove fat, and long-term use may damage the natural oil barrier of the skin, leading to dryness or irritation.
2、 The main uses of sodium dodecyl sulfate
Personal care products: Sodium dodecyl sulfate is widely used in personal care products such as shampoo, facial cleanser, shower gel, toothpaste, etc., mainly for cleaning and foaming. Due to its low cost and strong cleaning ability, many daily chemical manufacturers choose Sodium dodecyl sulfate as the main cleaning ingredient. In addition, it can quickly produce a lot of foam in water, improving the use experience of the product.
Household cleaning agents: Sodium dodecyl sulfate is also very common in household cleaning products such as laundry detergent, dishwashing detergent, floor cleaner, etc. Its excellent emulsifying properties can decompose grease and dirt, making it easier to wash away with water. In household cleaning products, Sodium dodecyl sulfate is usually used together with other surfactants to enhance the decontamination effect and increase the richness and durability of foam.
Industrial cleaning agents: Sodium dodecyl sulfate is also used in industrial cleaning agents, such as engine cleaning agents, metal surface treatment agents, etc. Due to its strong ability to dissolve oil and fat, Sodium dodecyl sulfate is particularly suitable for treating stubborn stains in industrial cleaning.
3、 Precautions for using sodium dodecyl sulfate
Although Sodium dodecyl sulfate is widely used for its efficient cleaning effect, its irritability and potential skin dryness issues have also received attention. The following are the precautions to be taken when using Sodium dodecyl sulfate:
Irritation to the skin: Sodium dodecyl sulfate has a strong ability to remove fat and may damage the natural barrier of the skin, leading to dryness or sensitivity. For people with sensitive skin, frequent use of products containing Sodium dodecyl sulfate may cause stinging, redness, or itching. Therefore, it is recommended to use milder alternative surfactants such as cocoyl glucoside for sensitive or dry skin.
Eye irritation: Sodium dodecyl sulfate has a certain degree of irritation to the eyes at high concentrations, especially when using products such as shampoo and facial cleanser. It is important to avoid contact with the eyes. If accidentally in the eyes, rinse immediately with clean water.
Alternative options: In recent years, consumer demand for mild and low stimulus products has increased, and some manufacturers have started using mild surfactants such as laurel betaine and cocoamidopropyl betaine to replace Sodium dodecyl sulfate. These alternative ingredients are mild, less irritating to the skin, and have a certain cleansing power, making them suitable for use on sensitive skin.
4、 Future prospects of sodium dodecyl sulfate
As consumers’ demand for mild and natural ingredients increases, the use of Sodium dodecyl sulfate is gradually decreasing. In the future, manufacturers may be more inclined to develop and use low stimulus, naturally sourced surfactants to meet market demand. However, as an efficient and low-cost surfactant, SLS still holds an undeniable position in the industrial and daily chemical fields, especially in products that require high cost and cleaning ability. Sodium dodecyl sulfate is still widely used.
Sodium dodecyl sulfate is an efficient and inexpensive surfactant with excellent cleaning, foaming, and emulsifying properties, widely used in personal care and household cleaning products. However, due to its potential irritation to the skin, it may gradually be replaced by mild substitute ingredients in the future. Consumers should make appropriate choices based on their own skin condition when choosing products containing Sodium dodecyl sulfate to reduce unnecessary irritation risks.
