A colloidal mixture contain particles with dimension under 1 000 nm.
This is a colloidal mixture.
Such a mixture is called a colloidal solution.
When particles are suspended in a viscous (thick) mixture. Lots of oatmeal based lotions are colloidal.
In science, there are three types of mixtures. These mixture types are, suspension mixture, colloidal mixture and a solution.
Homogenised milk is a homogeneous colloidal dispersion of the milk solids in the liquid milk. The colloidal particles are sized as per the requirements in high-speed colloidal mills. It is not a heterogeneous mixture.
A colloidal suspension is neither a mixture nor a solution.
A colloidal mixture is sometimes called a colloidal system, a colloidal suspension, or simply a "colloid." The smallest dimension of the minor component of a colloidal mixture can range from approximately one nanometer (1 billionth of a meter) to one micrometer (1 millionth of a meter). Examples of liquid colloidal mixtures are milk, paints, and muddy water. The medium can be a gas, in the cases of smog, smoke, or aerosol sprays. Some solids are considered to be colloidal mixtures, as in steel or foam rubber. A colloidal mixture is sometimes called a colloidal system, a colloidal suspension, or simply a "colloid."

This is a colloidal mixture, such as milk, the mixture though not made of soluble solids, colloidal solids are actually held in suspension in the solvent (water, alcohol, or oil) and do not readily precipitate from the fluid.
sand and water.
A colloid is a mixture in which one substance is divided into minute particles (called colloidal particles) and dispersed throughout a second substance. The mixture they form is called a colloidal dispersion. A colloidal dispersion consists of colloids in a dispersing medium. It doesn't have to be liquid.
Butter is a colloidal solution as it shows Tyndall effect. Tyndall effect is scattering of beam of light by the particles of colloidal solution. The dispersed phase in butter is liquid and dispersion medium is solid. The colloidal solution is always a part of heterogeneous mixture. Therefore, Butter is a heterogenous mixture.
all the colloidal solutions or emultios are microscopically heterogeneous....
