-Ceteareth-34 functions as an emollient, surfactant and emulsifier. 
-Ceteareth-34 is used in cosmetics such as facial moisturizer, conditioner, anti-aging treatment, conditioner, cleanser, sunscreen, exfoliant/scrub, depilatory cream and acne treatment.

-Ceteareth-34 has good wetting, emulsifying and cleaning properties. 
-Ceteareth-34 can be widely used in textile printing and dyeing, chemical fiber spinning, metal processing, cosmetics and other industries.
-A common functional ingredient that helps to keep the oil-loving and water-loving ingredients together (emulsifier), stabilizes and thickens the products.

-Ceteareth-34 is a derivative based on renewable vegetable raw materials and is used mainly in cosmetic and detergent applications.
-Ceteareth-34 is used primarily as an emollient, emulsifier and solubilizer. 
-Ceteareth-34 is usually used in combination with other compounds (alcohols and fatty acids), acting as an aid in dissolving the remaining ingredients of the formulation. 

-Ceteareth-34 due to the high degree of ethoxylation of cetostearyl alcohol shows a strong hydrophilic character, which is why it is perfect for creating stable oil-in-water emulsions (O / W). 
-Ceteareth-34 forms particularly stable emulsions in combination with other emulsifiers, such as e.g. glyceryl stearate.

Emollients are substances that soften and moisturize the skin and reduce itching and flaking. 
-Used in skin and hair care preparations, Ceteareth-34 creates an occlusive layer (film) on the surface. 
-Ceteareth-34 prevents excessive evaporation of water from the surface (an indirect moisturizing effect), which ensures softening and smoothing of the skin and hair. 

-Ceteareth-34 reduces the drying effect of anionic surfactants, leaving the skin surface moisturized and covered with a protective layer. 
-Ceteareth-34 also acts as a modifier of rheological properties, i.e. Ceteareth-34 improves the consistency of creams, lotions, hair conditioners, etc., ensuring an increase in viscosity.

-Ceteareth-34 influences the application properties of the formulation, by improving its distribution and lubrication. 
-In the detergent industry, Ceteareth-34 works great as the main ingredient of toilet blocks, also those that do not require plastic hangers.
-Ceteareth-34, nonionic emulsifier is used for external application in a wide range of prescription (Rx) and over the counter (OTC) products including emulsion, creams, suspensions, aerosols and foams.

WHAT IS CETEARETH?
The INCI names ceteareth-n (where n is a number) refer to polyoxyethylene ethers of a mixture of high molecular mass saturated fatty alcohols, mainly cetyl alcohol (m = 15) and stearyl alcohol (m = 17). 
The number n indicates the average number of ethylene oxide residues in the polyoxyethylene chain.
These compounds are non-ionic surfactants that work by attracting both water and oil at the same time, frequently used as emulsifiers in soaps and cosmetics.

Ceteareths (Ceteareth-2, Ceteareth-3, Ceteareth-4, Ceteareth-5, Ceteareth-6, Ceteareth-7, Ceteareth-8, Ceteareth-9, Ceteareth-10, Ceteareth-11, Ceteareth-12, Ceteareth-13, Ceteareth-14, Ceteareth-15, Ceteareth-16, Ceteareth-17, Ceteareth-18, Ceteareth-20, Ceteareth-22, Ceteareth-23, Ceteareth-24, Ceteareth-25, Ceteareth-27, Ceteareth-28, Ceteareth-29, Ceteareth-30, Ceteareth-33, Ceteareth-34, Ceteareth-40, Ceteareth-50, Ceteareth-55, Ceteareth-60, Ceteareth-80, Ceteareth-100) are liquids to waxy solids. 

In cosmetics and personal care products, Ceteareth ingredients are used in skin care products, moisturizers, hair conditioners, suntan and indoor tanning products and hair dyes, colors, and tints.

-Why is it used in cosmetics and personal care products?
Ceteareth-2 to -18, and Ceteareth-22, help to form emulsions by reducing the surface tension of the substances to be emulsified. 
Ceteareth-22 is also used to decrease the thickness of liquid cosmetics and personal care products. 
Ceteareth-20 to -40 help other ingredients to dissolve in a solvent in which they would not normally dissolve, and along with Ceteareths-50 to -100, clean the skin and hair by helping water to mix with oil and dirt so that these substances can be rinsed away.

Ceteareths are made from cetearyl alcohol, which is a mixture of cetyl and stearyl alcohol, and ethylene oxide. 
The numerical value represents the average number of molecules of ethylene oxide added to generate the specific Ceteareth ingredient. 
For example, Ceteareth-2 is made by reacting Cetearyl Alcohol with an average of 2 molecules of ethylene oxide.
