A humectant / h juː ˈ m ɛ k t ən t / is a hygroscopic (water-absorbing) substance used to keep things moist. They are used in many products, including food, cosmetics, medicines and pesticides. They are used in many products, including food, cosmetics, medicines and pesticides.
When hexylene glycol binds to these different locations, water is removed and the protein crystals anneal, which prevents ice formation during cryocrystallography techniques. [16] Incorporation of hexylene glycol into solution has been known to improve the resolution of X-ray diffraction making protein structures easily identifiable. [ 17 ]
The toy consists of small beads that stick to each other upon sprinkling with water. 1,4-Butanediol, which when ingested is metabolized to gamma-hydroxybutyric acid, was detected by GC-MS. [ 7 ] [ 8 ] ChemNet China lists the price of 1,4-butanediol at between about US$1,350–2,800/tonne, while the price for 1,5-pentanediol is about US$9,700/tonne.
Bepanthen eye and nose ointment (Germany) A vial of nasal spray containing panthenol, manufactured in Italy In pharmaceuticals, cosmetics, and personal-care products, panthenol is a moisturizer and humectant, used in ointments, lotions, shampoos, nasal sprays, eye drops, lozenges, and cleaning solutions for contact lenses.
Glycol caprylyl 1,2-Dihydroxyoctane 1,2-Octylene glycol. ... It is a common component of many creams and ointments, where it is used as a skin conditioning agent.
Water conditioners are formulations designed to be added to tap water before its use in an aquarium. [1] [2] If the tap water is chlorinated then a simple conditioner containing a dechlorinator may be used. These products contain sodium thiosulfate which reduces chlorine to chloride which is less harmful to fish.
Water: The most widely used due to its high heat capacity and thermal conductivity. Mono-ethylene glycol: Often used in a mixture with water to lower the freezing point for use in colder climates. Propylene glycol: Preferred in food production and other industries where toxicity might be a concern.
Water loss through the skin is normally about 4–8 g/(m 2 ⋅h). A layer of petrolatum applied to normal skin can reduce that loss by 50–75% for several hours. [4] Oils naturally produced by the human body moisturize through this same mechanism. [2] Humectants are hydrophilic and absorb water. They absorb water from humid air (when >70% ...
