Ceteareth-25 is a non-ionic polyoxyethylene ether of higher saturated fatty alcohols (cetyl/stearyl alcohol).
Ceteareth-25 is available as a white, waxy solid.
Ceteareth-25 is used as an emulsifier in oil/water emulsions.
Ceteareth-25 is compatible with all kinds of oils & active ingredients, is a very effective protective colloid that stabilizes all kinds of dispersed systems, and can be combined with other emulsifiers, optimal use with gel-forming thickeners.
Compared to Ceteareth-20, Ceteareth-25 has a bit more gel-forming and thickening properties.
Its chemical formula is C18H38O.
Ceteareth-25 is used as a solubilizing agent, emulsifier, cleansing agent, and surfactant in personal care.
As surfactant:
Ceteareth-25 effectively removes impurities and dirt from the surface of the skin and hair.
The particles of this surfactant surround the contaminants, which detach from the cleaned surface and are then washed away.
Ceteareth-25 is also an effective foaming agent.
In addition, Ceteareth-25 is responsible for the stabilization of foam and improves its quality in a mixture with anionic surfactants.
As emulsifier:
Due to its strong hydrophilic nature, Ceteareth-25 is perfect for creating oil-in-water emulsions.
Due to its very good emulsifying properties, it can be used for the preparation of emulsions at room temperature.
As solubilizer:
Ceteareth-25 enables the incorporation of hardly soluble or water-insoluble ingredients into an aqueous solution, such as fatty substances, plant extracts or fragrances.
Ceteareth-25 has a strong softening, moisturizing and conditioning effect.
Ceteareth-25 reduces the itching and peeling of skin.
Ceteareth-25 maintains the level of moisture at the right level by creating an occlusive layer on the surface of the hair and skin, which prevents excessive evaporation of water
Ceteareth-25 is a non-ionic polyoxyethylene ether of higher saturated fatty alcohols (cetyl/stearyl alcohol).
HLB value 16 (gives oil-in-water emulsions). Universal emulsifier to make o/w emulsions. Compatible with all kinds of oils & active ingredients.
Very effective protective colloid that stabilizes all kinds of dispersed systems.
Can be combined with other emulsifiers.
Optimal use with gel-forming thickeners.
Compared to ceteareth-20, ceteareth-25 has a bit more gel-forming and thickening properties.
Ceteareth-25 is a fatty alcohol that functions as an emulsifier and surfactant in cosmetics.
Ceteareth-25 may be plant- or animal-derived or made synthetically (Paula’s Choice Skincare uses the synthetic and plant-derived types).
Ceteareth-25 also helps to keep ingredients soluble within a formula, allowing them to remain dispersed evenly throughout an emulsion.
This ingredient 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-25 is part of a blend.
Ceteareth-25 is a non-ionic surfactant.
The commercial product is a white solid with a waxy consistency.
The solidification point of the product is about 40°C.
Ceteareth-25 is a derivative based on renewable vegetable raw materials and is used mainly in cosmetic and detergent applications.
Advantages of Ceteareth-25:

Ceteareth-25 is a non-ionic surfactant, which is a mixture of cetyl and stearyl alcohols ethoxylated with 25 moles of ethylene oxide.
The full chemical name of Ceteareth-25 is C16-18 alcohols, ethoxylated.
The specific numerical designation that uniquely identifies chemical compounds, the CAS number, for Ceteareth-25 is 68439-49-6.
This compound can be obtained from natural raw materials.
The physical and chemical properties of Ceteareth-25:
appearance:
-white solid with the consistency of a wax,
-faint, distinctive odour,
-good solubility in hot water,
-sensitive to pH changes (stable at low pH, hydrolyses at high pH),
-resistant to hard water,
-molar mass: approx. 1360 g/mol,
-density: approx. 1.020 g/ml (at a temperature of 60ᵒC),
-hydrophile-lipophile balance (HLB): approx 16,
-hydroxyl value: from 36 to 45 mg KOH/g,
-acid value: max. 1 mg KOH/g.
The main application of Ceteareth-25, among others in cosmetics, is primarily based on its emulsifying properties.
This is due to the structure of the molecule typical for surfactants.
The vast majority of cosmetics have the form of an emulsion.
This is the effect of the presence of a significant amount of ingredients of different chemical characteristics in the composition of the cosmetic formulation.
The Ceteareth-25 molecule, containing both a hydrophilic moiety (interacting strongly with water molecules) and a hydrophobic moiety (showing affinity for the oil phase), align at the phase boundary and, by reducing the surface tension, enable the combination of two immiscible phases (the water phase and the oil phase).
Due to its strong hydrophilic nature, Ceteareth-25 is perfect for creating oil-in-water emulsions.
Due to its very good emulsifying properties, it can be used for the preparation of emulsions at room temperature.
This is especially important in the case of active substances that are not very resistant to high temperatures.
As a surfactant, Ceteareth-25 is an ingredient in cosmetic products with cleaning properties.
Ceteareth-25 effectively removes impurities and dirt from the surface of the skin and hair.
The particles of this surfactant surround the contaminants, which detach from the cleaned surface and are then washed away.
In cosmetics, Ceteareth-25 is an effective foaming agent.
In addition, Ceteareth-25 is responsible for the stabilization of foam and improves its quality in a mixture with anionic surfactants.
Another role of this surfactant is to modify the rheological properties in formulations containing anionic surfactants by creating so-called mixed micelles.
The modification of rheological properties is the change in the viscosity of the product.
Achieving the desired value of the viscosity of the cosmetic formulation allows for obtaining the right consistency, which will ensure good performance characteristics and stability of the product.
Changing the rheological properties of the cosmetic improves its consistency.
As a solubilizer, Ceteareth-25 enables the incorporation of hardly soluble or water-insoluble ingredients into an aqueous solution, such as fatty substances, plant extracts or fragrances, which constitute an integral part of every cosmetic.
Ceteareth-25 has a strong softening, moisturising and conditioning effect thanks to the properties typical for emollients.
Ceteareth-25 reduces the itching and peeling of skin.
Ceteareth-25 maintains the level of moisture at the right level by creating an occlusive layer on the surface of the hair and skin, which prevents excessive evaporation of water.
Ceteareth-25 is a surfactant made from cetearyl alcohol, which can be derived from animals (not used by ecostore), synthetically produced, or made from plants oils such as coconut and palm. The '25' in the name refers to the number of ethylene oxide units in the molecule.
