K12 and AOS are both common anionic foaming agents used in daily chemical cleaning systems. They are widely used in shampoos, shower gels, hand washes, dishwashing detergents, laundry detergents, and hard-surface cleaners. Both can reduce the surface tension of water, making it easier for air to ...
In the daily chemical field, static electricity problems are mainly concentrated in hair and fabrics. Although the two appear different, the underlying issue is essentially the same: after friction, washing, and drying, charge separation occurs on the surface. Since hair fibers and textile ...
Sodium metasilicate is a commonly used inorganic alkaline builder in household cleaning, industrial cleaning, metal cleaning, and powdered detergent systems. Its basic chemical composition is Na₂SiO₃, and it can form different hydrates. This article focuses on three forms: anhydrous sodium ...
Microbial spoilage in daily chemical products essentially occurs when microorganisms find conditions in the product that are suitable for survival and reproduction. Microbial growth typically requires water, nutrient sources, a suitable temperature, and a source of contamination. Many daily ...
A defoamer is a functional additive used to break existing foam or inhibit the continued growth of foam. In daily chemical products, foam usually originates from surfactant systems. Surfactants reduce the gas-liquid interfacial tension, making it easier for air to be dispersed into bubbles. At ...
FMEE/MEE generally refers to fatty acid methyl ester ethoxylates or methyl ester ethoxylates, also known as ethoxylated fatty acid methyl esters. FMEE is a type of nonionic surfactant and belongs to the class of ether-ester surfactants produced by the ethoxylation of fatty acid methyl esters ...
Nitrate reduction is a key reaction in the biological nitrogen cycle that determines the fate of NO₃⁻. After NO₃⁻ is reduced to NO₂⁻, it can enter denitrification, DNRA, or assimilatory utilization pathways, which respectively affect nitrogen removal, nitrogen retention, and biomass ...
The same red color can appear in lipstick, shower gel, liquid foundation, and color-changing lip balm, but the formulation logic behind it is not the same. In lipstick, red colorants need to be evaluated for color payoff, coverage, color retention, and bleeding risk. In a transparent shower gel, ...
In the household and personal care chemical industry, the system more closely related to SDBS and more widely used in practical applications is linear alkylbenzene sulfonate, abbreviated as LAS. LAS is a mixture of homologues and isomers composed of alkylbenzene sulfonates with different ...
