What is the viscosity of body lotion?

The lotion tested in this protocol had an average viscosity of 424.40 mPa-s, a standard deviation of 1.68 mPa-s, and a %RSD (relative standard deviation) of 0.40%.

What is viscosity in cosmetics?

In scientific terms, viscosity is the measure of the internal flow resistance of a fluid. By comparing a high-viscosity material such as hair gel with a low-viscosity material such as body wash at the same temperature, the former flows slower than the latter (Figure 1).

What makes lotion viscous?

The viscosity of an emulsion is influenced by the size of its inner phase. The lotions we usually create at home tend to be oil-in-water emulsions, so in that case the larger the oil (internal) phase, the thicker the end product.

What are the properties of a body lotion?

How do you increase the viscosity of lotion?

16. The process for increasing the viscosity of cream, which comprises adding an acid to the cream substantially less than that which would impart an acid taste to the-cream, and heating the acid-treated cream to less than 100 C., and cooling the cream to produce a cream having a marked viscosity increase.

Fixing the Viscosity of Lotions and Cremes

Is lotion liquid or solid?

Is a lotion a solid? Because the lotion is solid, there is no need to package lotion in a plastic bottle. Also with natural ingredients, the process for creating a lotion bar is low impact.

What is body lotion made of?

In a nutshell: Water + Oil + Emulsifier + Preservative = Lotion or Cream. Both “lotion” and “cream” are made using the same process, the differentiator is in the percentage of water used in the recipe, which determines its viscosity. Less water = thicker product, a cream. More water = thinner product, a lotion.

What are the elements of lotion?

What is a thickener in lotion making?

Lipid Thickeners

They are used most often in creams and lotions. Some common types include Cetyl Alcohol, Stearyl Alcohol, Carnauba Wax, and Stearic acid.

What is the viscosity of body wash?

Body wash/shampoo have viscosity ranges from 5000 - 20,000 cps.

What does viscosity mean in skincare?

Viscosity is the measure of the thickness and density of a liquid or semi-fluid substance. The higher the viscosity, the thicker the substance. A product's viscosity is defined by its resistance to flow and in skincare, an essential component of quality control.

How is cream viscosity measured?

Instruments called “rheometers” and “viscometers” are used to measure viscosity of pharmaceutical liquids and semi-solid materials like creams/ ointments. Viscosity flow curves shown in the instrument display - see Figure 1 – characterize typical behavior of pharmaceutical products.

Is lotion a fluid?

It might be creamy to you but the TSA counts lotion as a liquid. So, you can bring lotion on a plane in your carry on but it must be in bottles or containers smaller than 3.4 ounces. Make sure you pack these containers in your one quart-sized bag.

How much oil do you put in lotion?

Creams are usually about 2/3 oil phase (oils, butters, waxes) and 1/3 water phase (all water soluble ingredients) while lotions are about 2/3 water phase and 1/3 oil phase. 5% beeswax is generally sufficient to give your emulsion body.

Is lotion a semi solid or liquid?

Semisolids, such as a creams, lotions, and ointments, and gels are commonly utilized dosage forms in topical and transdermal drug delivery.

What is the base of lotion?

A lotion's base is the lotion without added fragrance or coloring. Lotion base is what's left of the lotion, once the colorings and scents are removed. This base consists of an emulsifier, oil or butter, and water. Water and oil do not mix, and the types of oils used in lotions will turn rancid if left out over time.
