Bisabolol is a common soothing ingredient in cosmetics for sensitive-skin care, after-sun care, post-shave care, and skin-repair products. It is closely associated with German chamomile and can also be obtained from the Brazilian Candeia tree. Commercial production routes now include chemical ...
The cosmetic ingredient name of acetyl tetrapeptide-2 is Acetyl Tetrapeptide-2. It is a synthetic short peptide composed of four amino acids and modified by acetylation at the N-terminus. Its commonly cited sequence is Ac–Lys–Asp–Val–Tyr–OH, with the molecular formula C₂₆H₃₉N₅O₉, a relative ...
The International Nomenclature Cosmetic Ingredient name of avobenzone is Butyl Methoxydibenzoylmethane. Its Chinese chemical name is butyl methoxydibenzoylmethane. It is a dibenzoylmethane derivative and a β-diketone compound.
In skincare products, “377” usually refers to Phenylethyl Resorcinol, commonly known by the trade name SymWhite® 377. It is a resorcinol-based skin-brightening active ingredient mainly used to improve uneven skin tone, dullness, post-sun hyperpigmentation, and post-inflammatory ...
γ-PGA is a natural polymer composed of numerous linked glutamic acid units. Industrially, it is generally produced by microbial fermentation using Bacillus species and other microorganisms. Depending on the microbial strain and production conditions, γ-PGA may consist of D-glutamic acid, ...
Cellulose is a natural linear polysaccharide composed of glucose units linked by β-1,4-glycosidic bonds. It is an important structural component of plant cell walls. Native cellulose contains a large number of hydroxyl groups along its molecular chains. These chains readily form hydrogen bonds ...
In the production of cleansing products such as shampoos, body washes, hand soaps, and dishwashing detergents, AES is one of the commonly used primary surfactants. During winter production, many factories encounter a practical problem: after AES arrives, it becomes thickened, forms lumps, cannot ...
Polyquaterniums are commonly listed in cosmetic ingredient declarations in the form of “Polyquaternium-number,” such as Polyquaternium-7, Polyquaternium-10, Polyquaternium-22, Polyquaternium-37, and Polyquaternium-55. In the industry, PQ is often used as the abbreviation for Polyquaternium.
The skin is chronically exposed to multiple oxidative environments, including ultraviolet radiation, air pollution, ozone, visible light, and endogenous metabolic stress. The key to maintaining cutaneous homeostasis does not lie in a single antioxidant ingredient, but in a continuous defense ...
