Euxyl® K 100

Is an active ingredient for DIY skin care and homemade cosmetics from BulkActives.

Product details

INCI: Benzyl Alcohol (and) Methylchloroisothiazolinone (and) Methylisothiazolinone

Appearance: clear, colourless – yellowish liquid
Odour: characteristic
Flash point (ISO 2719): > 100 °C
Solubility: in emulsions.

In water Euxyl® K 100 is only limitedly soluble. In the polar solvents such as propylene glycol, Euxyl® K 100 is unlimitedly soluble. In non-polar solvents it is only limitedly soluble, in pure hydrocarbons it is practically insoluble.

Temperature stability: euxyl® K 100 should be incorporated into the product in the cooling phase at a temperature lower than 40 °C.

pH stability: High (alkaline) pH values (> 8.0) should be avoided when incorporating Euxyl® K 100. Acidic pH values have no negative influence on the effectiveness.

Suggested percentage: 0.05% to 0.21%

In practice, emulsions are preserved with 0.10 % Euxyl® K 100. On account of its special formulation the distribution of Euxyl® K 100 in water/oil systems is better than pure water-based preservatives. The products good effectiveness in w/o systems is attributable to this.

For shampoos, bath preparations and hand cleansing preparationsgood preservation results are achieved with 0.05 – 0.15 % Euxyl® K 100.

In sun protection preparations we recommend not exceeding a use-concentration of 0.10 % Euxyl® K 100.

For wet wipes good preservation results are achieved with 0.05 – 0.10 % Euxyl® K 100. Euxyl® K 100 is not recommended for products that are intended for mucous membranes.

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® K 100 with other ingredients have been established and are listed below:

Euxyl® K 100 is fully effective both in anionic as well as cationic and non-ionic systems. High pH values (> pH 8.0) should be avoided. Acidic pH values have no negative influence on the effectiveness.

Euxyl® K 100 proved to have good compatibility with anionic surfactants such as sulphates, ether sulphates and sulphosuccinates, as well as with non-ionogenic surfactants.

Euxyl® K 100 is inactivated by sulphite ions. Excessive sulphite > 10 ppm must be avoided.

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 K 100 data sheet

Euxyl® K 100 is a non-formaldehyde releasing, paraben and phenoxyethanol free liquid preservative. Its use is permitted both in products that remain on the skin as well as in rinse-off products. Euxyl® K 100 is not recommended for products that are intended for mucous membranes or for lipsticks or toothpastes.

Euxyl® K 100 has a broad, balanced spectrum of effect against bacteria, yeasts and mould fungi. It acts even in very low use concentrations and has good vapour phase effectiveness. Euxyl® K 100 is effective at a low (acidic) pH.

Microbiological effectiveness

Euxyl® K 100 is equally effective against bacteria, yeasts and mould fungi. It is a typically biostatic product with the biocidal properties necessary for practical use.

For Euxyl® K 100 to perform effectively in destroying organisms in products already contaminated, a minimum contact time of 48 hours is necessary.

Since the effect of euxyl® K 100 takes place through chemical reactions with the microorganisms, when it is used in heavily contaminated products loss of active ingredient must be taken into account.

Good production hygiene, as well as the use of raw materials with low microorganism levels as a result of correct raw material control are of course vital prerequisites for the production of microbiologically faultless finished products.
