EUXYLK 700 is a liquid cosmetic preservative, which can be used in leave-on as well as rinse-off products. EUXYL K 700 was developed for use in cosmetic formulations with a skin-friendly pH value up to 5.5. EUXYL K 700 has a broad, balanced spectrum of effect against bacteria, yeasts and mould fungi as well as a good vapour phase effectiveness. As a result of the special preparation, the tendency to discolouration known for sorbic acid can be reduced or prevented. In addition EUXYL K 700 can be stored for a longer period.

EUXYL K 145 is a liquid cosmetic preservative, which can be used in leave-on as well as rinse-off products. EUXYL K 145 is not recommended for products that are in tended for mucous membranes, or for lipsticks or toothpastes. EUXYL K 145 has a broad, balanced spectrum of effect against bacteria, yeasts and mould fungi. It acts even in very low useconcentrations.

EFFISIN PG is a multifunctional active for cosmetics. It shows good antimicrobial effect as well as excellent moisturizing property. Also it can improve skin feel and stability of cosmetic formulations. The recommended use levels relate to the total formulation in each case. The values given are recommended guidelines. To prove the antimicrobial efficacy and evaluate the optimum use level a repeated challenge test is recommended (e.g. at schülke Technical and Microbiological department).

EUXYL K 340 is fully effective both in anionic as well as cationic systems. High pH values (> pH 8.0) should be avoided. Acidic pH values have no negative influence on the effectiveness. EUXYL K 340 proved to have good chemical compatibility with anionic surfactants such as sulphates, ether sulphates and sulphosuccinates, as well as with non-ionogenic surfactants. Ethoxylated surfactants may lead to loss of effectiveness.
