Hydrocolloids are used in some skin care products

A hydrocolloid is defined as a colloid system were the colloid particles are disperesed in water. A colloid system is simply a system or mixture were two substances are interspersed between each other. A hydrocolloid has colloid particle spread throughout water and depending on the quantity of water available can take on different states, e.g: gel or sol (liquid). Hydrocolloids can be either irreversible (single state) or reversible. For example, Agar, a reversible hydrocolloid of seaweed extract, can exist in a gel and sol state and alternate between states with the addition or elimiation of heat.
