Composition
Polyethylene glycol
H(OCH2CH2)nOH

CAS-No.: 25322-68-3
INCI-designation: PEG-8
PEG 400 is a clear viscous liquid polyethylene glycol at room temperature.
PEG 400 is soluble in water and polar organic solvents like acetone or methanol.
PEG 400 is insoluble in pure hydrocarbons and displays typical chemical reactions of alcohols/diols.
PEG 400 is suitable for hand dishwashing detergents, wool and fine-fabric washing powders for manual washing, hand and all-purpose wash pastes, hard surface cleaners, all liquid wash and cleaning agents, especially suited for highly concentrated products, viscosity regulators, detergent boosters, solubilizers.
Product properties of PEG 400:
PEG 400 and PEG 400 G are clear viscous liquid at room temperature.
PEG 400 / 400 G can be supplied in tank trucks or in steel drums.
PEG 400's two hydroxy end groups as well as its ether groups mainly control the physical and chemical properties of PEG 400.
Therefore PEG 400 is soluble in water and polar organic solvents like aceton or methanol.
PEG 400 is a non-volatile humectant, solubilizer, moisturizer and fixative.
PEG 400 is also used in hair styling products as a plasticizer and anti-static agent.
PEG 400 offers softening, cleansing and non-irritating properties.
PEG 400 provides low toxicity and hygroscopic effect.
PEG 400 can be used in creams and all preparations that tend to dry out.
PEG 400 also acts as a cleansing agent in face lotions and as non-greasy lubricant and perfume stabilizer in after-shave lotions.
PEG 400 can be used in lipsticks as solubilizers for tetrabromo fluorescein and its derivatives and in hair care products where improves the consistency of non-greasy hair care products which can be washed out with clear water.
PEG 400 counteracts the tendency of these products to dry to a brittle film.
PEG 400 has very low water content, good biodegradability and is compatible with hard water.
PEG 400 is also applicable in toothpaste where it improves consistency and storage stability.
PEG 400 is insoluble in pure hydrocarbons.
PEG 400 displays typical chemical reactions of alcohols/diols.
In comparision to the standard PEG 400 the alkali ion residue of PEG 400 G is minimized.
Therefore PEG 400 G can be used for polyurethane synthesis.
The solidification point, of PEG 400 is about 6°C.
PEG 400 is a liquid PEG excipient grade product, produced under IPEC GMP conditions.
PEG 400 is specified according to the requirements of the main international ICH guidelines and monographs.
Storage of PEG 400:
When stored in a cold, dry place in a closed container PEG 400 or 400 G can be kept for at least two years.
Applications of PEG 400:
Based on their physical and chemical characteristics polyethylene glycols are used for a wide variety of applications.
Fields of applications of PEG 400:
- Reactive diol/polyether component in polyester or polyurethene resins
- Component of auxiliaries for leather and textile processing
- Cosmetic / pharmaceutical formulations (e.g. humectant or solubilizer for creams, shampoos, tooth paste and injection fluids)
- Lubricant and mould release agent for rubber and elastomer processing
- Plasticizer and binder for ceramic and concrete manufacturing
- Component of lubricant formulations
- Water soluble, lubricating component in metal working fluids
- Humectant for paper, wood and cellulose films
- Solvent and humectant for dyes and inks
- Modifier for production ofregenerated viscose
- Humectant and plasticizer for adhesives
- Heat transfer medium
