Oleth-3 Phosphate is an ester of Oleth-3 and phosphoric acid. It functions as an emulsifier and surfactant in cosmetic formulations. This ingredient helps to stabilize emulsions, improving the texture and consistency of products, and enhances the solubility of other ingredients.

Chemical Composition and Structure:

Oleth-3: A polyethoxylated derivative of oleyl alcohol, which acts as a nonionic surfactant.
Phosphoric Acid: An inorganic acid that is used to form the phosphate ester.

Physical Properties:

Oleth-3 Phosphate is typically a clear or slightly cloudy liquid. It is soluble in water and has emulsifying properties that help blend oil and water phases in cosmetic formulations.

Production Process:

Preparation of Oleth-3:
Oleyl alcohol is ethoxylated to produce Oleth-3.
Esterification:
Oleth-3 is reacted with phosphoric acid to form Oleth-3 Phosphate.
Purification:
The ester is purified to remove any unreacted materials or by-products.
Incorporation:
The purified Oleth-3 Phosphate is incorporated into cosmetic formulations as an emulsifier or surfactant.

Applications:

Emulsifier: Helps to stabilize emulsions and improve product texture.
Surfactant: Enhances the solubility and dispersion of other ingredients.

Environmental and Safety Considerations:

Oleth-3 Phosphate is generally regarded as safe for use in cosmetics. It is important to use it according to established guidelines to avoid any potential skin irritation or allergic reactions. Ensure that the ingredient is sustainably sourced and free from harmful contaminants.

INCI Functions:


Surfactant - Cleansing agent. Cosmetic products used to cleanse the skin utilise the surface-active action that produces a lowering of the surface tension of the stratum corneum, facilitating the removal of dirt and impurities.
