PEG-8 is a synthetic polymer that works to bind moisture to skin and as a solvent for other cosmetic ingredients, helping them penetrate more efficiently.
PEG-8 are polymers of ethylene glycol.
PEG-8 represents the average number of ethylene glycol units.
PEG-8 is used as an emollient in the formulation of cosmetic products.
PEGs are a very broad group of cosmetic ingredients.
They are all derivatives of ethylene glycol.
One of these derivatives is a compound called whose INCI name is PEG-8.
The characteristic properties of PEG-8 include PEG-8 ability to form emulsions, retain moisture and solubilise.
Thanks to PEG-8 properties, PEG-8 is used in the cosmetic industry, construction, and in the production of fertilisers.
PEG-8 is used for synthetic polymers of ethylene oxide.
These polymers may be contaminated with potentially toxic manufacturing impurities such as 1,4-dioxane.
A smallish polymer molecule (created from repeated units of Polyethylene glycol, aka PEG) that's used as a solubilizer and viscosity control agent.
PEG-8 is a clear, colorless liquid that is water-soluble and water-binding (aka humectant) and can help to solubilize sparingly-water soluble things (e.g. vanilla, perfumes) into water-based formulas.
Thanks to PEG-8 water-binding ability, PEG-8 also prevents the drying out of formulas, especially when combined with the fellow hygroscopic agent, sorbitol.
PEG-8 is a safe solvent and carrier for cosmetic use.
PEG-8 can act as a solvent in many substances.
PEG-8 is also a safe carrier.
Properties of PEG-8:
The group of synthetic ethylene oxide polymers is generally referred to as PEGs.
These include derivatives of ethylene glycol that are formed by the condensation polymerisation reaction.
The polymer chain structure for polyethylene glycols is varied.
Depending on the number of ethylene glycol units in the molecule, “different” PEGs are distinguished.
PEG-8 is therefore a lauric acid monoglyceride ethoxylated with 8 moles of ethylene oxide.
The CAS number of the compound is 25322-68-3.
PEG-8 is a colourless liquid that dissolves well in water.
PEG-8 characteristic feature are strong hygroscopic properties, which indirectly result in very good solubility of active substances.
PEG-8 is an ethylene glycol derivative with the highest molecular mass and keeps liquid form at room temperature.
Applications of PEG-8:
A number of advantages of PEG-8 make this surfactant readily used in industries other than the cosmetic industry.
Industrial cleaning is an important field of industry that needs effective and efficient surfactants.
PEG-8, with its good anti-electrostatic emulsifying properties, is a popular ingredient in products aimed for industrial cleaning.
As an anti-electrostatic agent, PEG-8 is also used in metalworking processes or in dye baths as a levelling agent.
Applications in cosmetic products of PEG-8:
Emulsifier:
The application of PEG-8 in cosmetics, personal care products or products used in various industries relies heavily on the emulsifying properties of the compound.
Emulsifiers are substances that are responsible for stabilising formulations.
Many cosmetics and industrial products require two naturally unmixable ingredients to be combined.
These are usually oil-in-water or water-in-oil emulsions.
Such combination necessitates the use of an emulsifier such as PEG-8 since PEG-8 gives the right structure and texture to the product.
Humectant:
As a humectant, PEG-8 is responsible for retaining a constant level of moisture.
PEG-8 can absorb moisture and bind with water.
Proper hydration is important, for example, for ensuring proper skin function.
PEG-8 prevents the cosmetic formulation from drying (or crystallisation).
PEG-8 also serves as a solvent for other ingredients contained in cosmetics.
Solubiliser:
The production of cosmetics involves mixing together ingredients of differing chemical nature in order to obtain a uniform texture of the formulation.
The use of PEG-8 in the production process allows to accelerate the distribution of ingredients in the liquid base and to significantly improve the quality of the process.
As a solubiliser,PEG-8 mediates the dissolution process.
PEG-8 is characterised by PEG-8 ability to form a dispersion, which greatly facilitates the final application of the cosmetic formulation.
PEG-8 is a synthetic polymer that works to bind moisture to skin and as a solvent for other cosmetic ingredients, helping them penetrate more efficiently.

Safety of cosmetics containing PEG-8:
An independent scientific body, Cosmetic Ingredient Review (CIR), which evaluates the safety of certain chemicals in cosmetic formulations, has clearly identified PEG-8 as a safe substance.
The chemicals that make up the ethylene glycol derivatives group are not toxic to the skin.
Neither do they cause irritation or allergic reactions.
Storage of PEG-8:
Can be stored at room temperature But close the bottle tightly And sealed from direct sunlight or heat, the product is at least 2 years old
