202 results about "Ammonium lauryl sulfate" patented technology

Ammonium lauryl sulfate (ALS) is the common name for ammonium dodecyl sulfate (CH₃(CH₂)₁₀CH₂OSO₃NH₄). The molecule consists of a long nonpolar hydrocarbon chain and a polar sulfate end group, the combination of which make the material a surfactant. These two components allow the compound to dissolve among both polar and non-polar molecules. ALS is classified as an alkyl sulfate and is an anionic surfactant found primarily in shampoos and body-wash as a foaming agent. Lauryl sulfates are very high-foam surfactants that disrupt the surface tension of water in part by forming micelles around the highly polar water molecules at the surface-air interface. ALS has a pH slightly less than 7 making it a mildly acidic.

Preparation method of quaternary ammonium salt modified antibacterial textile and antibacterial textile

InactiveCN109577000AFully quaternizedEfficient broad-spectrum antibacterialFibre treatmentQuaternary ammonium cationSodium sulfate
The invention relates to a preparation method of a quaternary ammonium salt modified antibacterial textile. The preparation method includes the following steps that firstly, a textile base material isput into a mixed solution of vinyl monomers containing tertiary amine groups and sodium lauryl sulfate for a grafting polymerization reaction, so that a grafted tertiary amine group textile base material is obtained; secondarily, the grafted tertiary amine group textile base material and halogenated hydrocarbon have a reaction, so that the quaternary ammonium salt modified antibacterial textile is obtained. Through addition of sodium lauryl sulfate into a grafting precursor solution, a hydrogen abstraction reaction of sodium lauryl sulfate and delocalization of alkyl halide, delocalization electric charges are generated, styrene monomers containing tertiary amine groups are efficiently grafted onto the textile, activated alkyl halide can be more fully quaternized, and finally quaternary ammonium salt is bonded onto the textile with a high grafting rate; in this way, stable and efficient broad-spectrum antibacterial and sterilizing effects are realized, and the preparation process is simplified greatly.
