The use of sodium dodecy sulfate（SDS/SLS/SK12）) in pharmaceutical industry
Sodium dodecyl sulfate is an important additive in the pharmaceutical industry, but it must be used under reasonable norms and standards to ensure that it promotes drug development and application while ensuring the safety of patients. The following are some specific application cases of sodium dodecyl sulfate in the pharmaceutical industry:
Improve drug solubility: In some pharmaceutical preparations, such as some fat-soluble drugs, sodium dodecyl sulfate can be used as a solubilizer. It helps the drug disperse better in the solvent, improving its bioavailability. For example, in oral preparations containing insoluble ingredients, adding an appropriate amount of sodium dodecyl sulfate can make the drug dissolve more evenly and facilitate absorption by the body.
Promote the disintegration of tablets: In the production of tablets, adding a certain amount of sodium dodecyl sulfate can improve the wettability of tablets, accelerate the penetration of water, thereby increasing the dissolution rate of drugs, so that the tablets disintegrate faster. For example, a prescription for a dispersible tablet may include Sodium Lauryl sulfate to ensure that the tablet breaks down quickly after taking it, releasing the active ingredient.
Application of emulsifier: It can be used to prepare oil-in-water (O/W) emulsion matrix. For example, in a topical cream, sodium lauryl sulfate can be used as an emulsifier, so that the oil phase and the water phase are fully mixed to form a stable emulsion. The usual dosage is generally 5 ~ 20g/L, but the excessive dosage has little effect on reducing the surface tension. In order to achieve a better emulsifying effect, it is often combined with other water-in-oil (W/O) emulsifiers (such as glycerol monostearate, sorpitan fatty acid, etc.) to adjust the hydrophilic lipophilic balance value (HLB value) of the cream system.
Drug analysis and detection: In the content detection of febuxostat tablets and other drugs, high performance liquid chromatography-mass spectrometry (HPLC-MS) can be used. Sodium dodecyl sulfate is a common tablet excipient, and its content can be accurately determined by HPLC-MS method. The method overcomes the disadvantages of low sensitivity and poor selectivity of other detectors for sodium dodecyl sulfate, and integrates the high separation ability of liquid chromatography with the high sensitivity and strong specificity of mass spectrometry, making the analysis fast and convenient. For example, the specific operation is to accurately weigh the sample powder containing a certain amount of sodium dodecyl sulfate, place it in the measuring bottle, add water and ultrasonic to dissolve sodium dodecyl sulfate, then dilute it to the scale, shake it well, filter it for detection.
Surface functionalization modification: The use of cationic surfactants (such as cetyltrimethyl ammonium bromide) and anionic surfactants (such as sodium dodecyl sulfate) to modify the surface functionalization of red carbon dots can greatly improve the fluorescence quantum yield of red carbon dots and the solubility in water. For example, sodium lauryl sulfate was found to be highly selective to copper ions (Cu2+), a property that could be used in related detection or analytical applications.
