Product details

INCI: Ethylhexylglycerin (and) Phenoxyethanol

Appearance: clear, colourless –nearly colourless liquid
Odour: characteristic
Flash point (DIN 51 758): > 100 °C

Solubility: in emulsions.

Euxyl® PE 9010 exhibits limited solubility in water. 100 g of water at 20 °C dissolves 1.0 g of Euxyl® PE 9010.

In polar solvents such as 1,2-propylene glycol, propanol, or acetone, Euxyl® PE 9010 is readily soluble.

In polyalcohols such as glycerol and sorbitol Euxyl® PE 9010 is moderately soluble.

In aliphatic hydrocarbons with hydrophilic groups such as 2-octyldecanol and isopropyl myristate, Euxyl® PE 9010 exhibits limited solubility.

In pure aliphatic solvents, it is slightly soluble.

Temperature stability: Euxyl® PE 9010 is stable to temperature. As a result of the good solubility of Euxyl® PE 9010, an easy dispersion in the various systems even at low temperature is possible. Euxyl® PE 9010 is effective in pH-ranges up to 12.

pH stability: Euxyl® PE 9010 is stable to pH. Euxyl® PE 9010 is effective in pH-ranges up to 12

Suggested percentage: 0.5% to 1.1%

In practice, emulsions are preserved with 0.5 – 1.0 % Euxyl® PE 9010.

Euxyl® PE 9010 is clearly soluble in use-concentrations of 0.5 – 1.0 %. It can tolerate high salt content. A high load of surfactants can result in a loss of efficacy.

For wet tissues, good preservation results are achieved with 0.5 – 1.0 % Euxyl® PE 9010.

Formulas containing natural raw materials have a higher risk for microbial contamination. Microorganisms introduced by this pathway are quickly eliminated by Euxyl® PE 9010.

Chemical compatibility: In general, it is possible for interactions to occur between various active ingredients and auxiliary substances in cosmetic formulations. Thus, certain incompatibilities of Euxyl® PE 9010 with other ingredients have been established, and are listed below.

Euxyl® PE 9010 shows a good compatibility with salts. Euxyl® PE 9010 can be used in pH-ranges up to 12.

A high load of surfactants can lead to loss in effectiveness.

In general Euxyl® PE 9010 displays good compatibility with the ingredients of cosmetics. No discolourations have been detected.

Euxyl® PE 9010 shows no interaction with sulphite ions.

Euxyl® PE 9010 shows no interaction with pigments such as TiO2.

Storage: in the original container at room temperature.

Country of manufacture: Not disclosed by manufacturer

Manufacturer: Schülke & Mayr GmbH (Germany) - A company of the Air Liquide Group

Manufacturer's data: Euxyl PE 9010 data sheet

Euxyl® PE 9010 is a non-formaldehyde releasing AND paraben free preservative system which is equally effective against bacteria, yeasts and mould fungi.

Euxyl® PE 9010 is stable to hydrolysis, temperature and pH. As a result of the good solubility of Euxyl® PE 9010, an easy dispersion in the various systems even at low temperature is possible. Euxyl® PE 9010 is effective in pH-ranges up to 12 (acidic to alkaline). Gels preserved with Euxyl® PE 9010 stay clear and transparent.

Phenoxyethanol is a well-known, accepted cosmetic preservative. With Euxyl® PE 9010, Schülke & Mayr breaks new ground: an innovative, multifunctional additive enhances the efficacy of phenoxyethanol. The addition of thylhexylglycerin affects the interfacial tension at the cell membrane of microorganisms, improving the preservative activity of phenoxyethanol

Toxicology

Euxyl® PE 9010 is used as a preservative for cosmetics and toiletries. The product is used at a recommended use-concentration of 0.5 – 1.0 %. In accordance with the conditions stipulated in Directive 76/768/EEC, Euxyl® PE 9010 may be used in cosmetic preparations (leave-on and rinse-off) in a use-concentration up to a maximum of 1.1 %.

As active substance, phenoxyethanol (90 %) is used in Euxyl® PE 9010. As an auxiliary compound, the formulation additionally contains ethylhexylglycerin in a concentration of 10 %. Both substances have undergone extensive toxicological
testing. On the basis of the results, with the given upper concentration limit of 1.1 %, Euxyl® PE 9010 can be considered safe for the preservation of cosmetics and toiletries.

Furthermore a skin tolerability study (occlusive patch test) of Euxyl® PE 9010 compared to phenoxyethanol showed that there is no difference in skin tolerability between Euxyl® PE 9010 and phenoxyethanol. During the entire test period no reactions neither to phenoxyethanol nor to Euxyl® PE 9010 used in the maximum use concentrations could be observed. This skin tolerability test has been carried out on Caucasian skin in Germany and on Japanese skin in Japan.
