what is difference between gel and hydrogel?
suggest me safe material for making curcumin-hydrogel for oral administration.
As polymeric networks both gels and hydrogels are similar chemically, but they are physically distinct. Gels can be defined as the semi-solid system in which small amount of solid is dispersed in large amount of water. They possess more of solid like behaviour than liquid like behaviour. Sometimes hydrogels are also described as aqueous gels because of the prefix “hydro”. Hydrogels are nothing but a cross-linked network of hydrophilic polymers which is already swollen in water. They possess the ability to absorb large amounts of water and swell while maintaining their 3D structure.You can refer this paper to have a clear idea.
Gel is the common term for all kind of material which form gelatinous appearance. While hydrogel is the sub division of gel which forms gelatinous material in water.
Dear,
Gel can not swell in water but hydrogel has tendency to absorb water and swell.
Gel is semisolid system and hydrogel is like aqueous gel which is swell in water or also already swollen in water, made up of three dimensional crosslinked network of hydrophilic polymers.

the gels are semi-solid materials made of hydrophilic polymeric systems comprising small amounts of solids,dispersed in relativily laege amounts of liquid
hydro-gels are hydrophillic in nature. they are highly absorbent in nature. one can control their swelling by altering the pH, temperature etc.whereas, Gel is a generalised one. Hydro-gel comes under gel.
