Indoline, also known as 2,3-dihydro-1H-indole and in Chinese as 2,3-dihydroindole, has the CAS number 496-15-1, the molecular formula C₈H₉N, and a relative molecular mass of approximately 119.16.
The essence of a powdered fragrance is to use a liquid fragrance as the aromatic core and immobilize fragrance molecules within a solid carrier, wall-material matrix, or capsule structure through adsorption, embedding, inclusion, or encapsulation. The result is a composite fragrance raw material ...
Palm-derived isomeric alcohol polyoxyethylene ether PLE-S9 is a polyoxyethylene ether-type nonionic surfactant produced by the ethoxylation of palm-derived or plant-derived isomeric fatty alcohols. Its molecular structure is typically composed of an isomeric or branched fatty alcohol hydrophobic ...
In household and personal-care raw materials, anionic surfactants are among the most important cleansing surfactants. They are typically composed of a hydrophobic hydrocarbon chain and a negatively charged hydrophilic head group. In aqueous solution, they can adsorb at gas/liquid, oil/water, and ...
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 ...
