For example, the long-finned pilot whale secretes an enzymatic gel that rests on the outer surface of this animal and helps prevent other organisms from establishing colonies on the surface of these whales' bodies.

Gels are jelly-like colloidal systems in which a liquid is dispersed in a solid medium. The majority of commonly used gels are hydrophilic colloidal solutions, in which a diluted solution is formed as elastic semi-solid masses under appropriate conditions.

Jan 16, 2020 · A gel is a sol in which the solid particles are meshed such that a rigid or semi-rigid mixture results. Cross-linking within the gel's polymer or colloidal network causes a gel to behave as a solid in its steady-state and makes it feel tacky.

The most common gel example is jelly, where you can see the continuous phase (gelatin in granules or powder) and the dispersed phase (water). The continuous phase gives the gel consistency and prevents it from flowing freely, while the dispersed phase prevents it from becoming a compact mass.

Jan 9, 2025 · What are some examples of gel in everyday life? Gel is used in a wide range of everyday products, including cosmetics, pharmaceuticals, and food. For example, hair gel is used to style and hold hair in place, while gel toothpaste is used to clean and whiten teeth.

Apr 20, 2020 · A gel is a colloidal system in which the dispersed phase is liquid and the dispersion medium is solid. e.g. when warm sol of gelatin is cooled, it sets to a semi-solid mass which is a gel. Jellies, jams, curd, butter, shoe polish, etc. are gels.

Dec 7, 2024 · Definition: Gels are semisolid dosage forms in which a liquid phase (water or oil) is entrapped in a three-dimensional cross-linked polymeric network, resulting in a jelly-like consistency. Gels are used for topical, oral, ophthalmic, nasal, or rectal applications, depending on the active ingredient and formulation. 1.

May 12, 2024 · What are Gels? – A gel is a jelly-like colloidal system in which a liquid is dispersed in a solid medium. – For example, when a warm sol of gelatin is cooled, it sets to a semisolid mass which is a gel. – The process of a gel formation is known as Gelation. Explanation:

Jun 1, 2018 · Gels are pretty common materials – many of us style our hair with hair gel, wash ourselves with shower gel, eat jelly babies and brush our teeth with gelatinous toothpaste afterwards. But here’s an interesting question: how do gels fit …

Apr 6, 2025 · These are known as gels and the process is known as gelatin. For example: gelatin dissolved in warm water forming a colloidal solution which when cooled sets to a jelly. Other example includes gum Arabic, agar, silicic acid, ferric hydroxide, cheese etc.
