MDL Number: MFCD03098567
Formula:C18H38O

The group of ceteareth ingredients are synthetic compounds that are synthesized through a process known as ethoxylation, a chemical reaction in which ethylene oxide is added to a substrate. 
In regards to the ceteareth ingredients, there are two substrates: 
Cetyl alcohol and stearyl alcohol, which are both naturally derived from coconut oil. 

The number associated with the ceteareth- 40 indicates the average number of repeating ethylene oxide units in the molecule, in this case 40. 
There are a total of 32 different types of ceteareth ingredients.
Ceteareths, used in a large number of cosmetics as surfactants, are the polyethylene glycol (PEG) ethers of Cetearyl Alcohol (q,v.).

The polyethylene glycol ethers of cetearyl alcohol are called ceteareths. 
The '40' in the name refers to the number of ethylene oxide units in the molecule.
Ceteareth-40 is a surfactant made from cetearyl alcohol, which can be derived from animals, synthetically produced, or made from plants oils such as coconut and palm. 
May be plant or animal derived

Ceteareth-40 is an ether of fatty alcohols like stearyl alcohol or cetyl that are highly saturated. 
Ceteareth-40 is non-ionic polyoxyethylene that is odourless and is available in the form of pellets of white colour. 
Ceteareth-40 is an effective emulsifier and surfactant and also possesses emollient properties. 

Ceteareth-40 can be combined with synthetic and vegetable oils and minerals. 
Ceteareth-40 acts as an emulsifier in the formulation of skincare products, which is essentially required in the formulation containing water and oil. 
Ceteareth-40 helps bind the water and oil with each other and helps in stabilizing the product.

Cetearyl-40 is compatible with a wide range of oils and is soluble in both water and isopropyl alcohol. 
Ceteareth-40 helps produce emulsions by decreasing the surface tension of ingredients that are needed to be emulsified. 
Cetearyl-40 also proves to effectively reduce the viscosity or thickness of solutions used to make personal care products and liquid formulas. 

Ceteareth-40 also helps other cosmetic raw materials to dissolve quickly in solvents.
Helps keep ingredients soluble within a formula
Adds body to creams and lotions

Ceteareth-40 is one of several ceteareths deemed safe as used in cosmetics. 
Concentration ranges from 1.3–10% depending on the type of formula and desired aesthetics; lower amounts may also be used, especially if Ceteareth-40 is part of a blend.
Ceteareth-40 is the polyethylene glycol ether of cetearyl alcohol. 

Ceteareth-40 is easily soluble in water, ethanol, ethylene glycol and other organic solvents, and are stable to acids, alkalis, and hard water.
Ceteareth-40 belongs to non-ionic surfactants from the group of ethoxylated fatty alcohols, INCI name: Ceteareth-40. 
Ceteareth-40 is based on high molecular mass alcohol of natural origin. 

Ceteareth-40 is a non-ionic surfactant. 
Ceteareth-40 is a white solid with a waxy consistency. 

USES and APPLICATIONS of CETEARETH-40:
-Surfactant:
Surfactant is the other name for surface active agents. 
Surfactants are compounds that lower the surface tension between two substances, such as two liquids or a liquid and a solid. 
In skincare products, surfactants work to degrease and emulsify oils and fats and suspend dirt, allowing them to be washed away. 
This is possible because while one end of the surfactant molecule is attracted to water, the other end is attracted to oil. 
Thus, surfactants attract the oil, dirt, and other impurities that have accumulated on your skin during the day and wash them away. Due to these properties, Ceteareth-40 can be found in many different cleansers and body washes.

-Emulsifier and stabilizer:
Ceteareth-40 also functions as an emulsifier. 
An emulsifier is needed for products that contain both water and oil components, for example, when oils are added to a water-based formula. 
When water and oil are mixed together they will often separate and split in the product over time. 
To address this problem, an emulsifier can be added to produce a stable emulsion.
As an emulsifier, ceteareth-40 consists of a water-loving hydrophilic head and an oil-loving hydrophobic tail. 
The hydrophilic head is directed to the aqueous phase and the hydrophobic tail to the oil phase. 
Once again, ceteareth-40 reduces the surface tension by positioning itself at the oil/water or air/water interface, which has a stabilizing effect on the emulsion.

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.
