A zwitterion refers to a molecule that contains both a formal positive charge and a formal negative charge within the same molecule, while remaining electrically neutral overall. This type of structure is also commonly referred to as an inner salt structure. The International Union of Pure and ...
Amino acid surfactants are a class of surfactants that use amino acids or amino acid-derived structures as hydrophilic groups and typically introduce hydrophobic chains through fatty acyl groups. In personal care cleansing products, the most common types are N-acyl amino acid salts. Typical ...
In daily chemical products, “enzymes” usually do not refer to a single chemical substance, but rather to a class of functional ingredients associated with microbial fermentation, enzymatic transformation, or enzyme activity. They can be used in facial cleansers, body washes, shampoos, ...
Amide bonds, peptide bonds, and ester bonds are widely present in drug molecules, peptides, natural products, fine chemicals, and functional materials. For synthetic chemists, the key question in these reactions is usually not simply “whether the target bond can be formed,” but whether the ...
In metallographic analysis, a sample usually needs to undergo cutting, mounting, grinding, and polishing to obtain a flat observation surface with minimal scratches. After polishing, the metal surface may appear bright and mirror-like, but this does not mean that grains, grain boundaries, phase ...
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 ...
