Chemical name: Alkyl hydroxyethyl dimethyl ammonium chloride
Detergency booster in presence of anionc-based formulations (HDWL) and cationic cleaner.
Easily dosed, efficient, versatile.
Praepagen HY acts as a detergency booster in presence of anionic surfactants.
Praepagen HY is a cationic surfactant with high degreasing power, easy to dose dose, efficient and versatile.
Praepagen HY could be classified as a typical cationic surfactant whose solubility or hydrophilic characteristics are improved by the presence of a hydroxyl group in Praepagen HY structure.
This characteristic allow Praepagen HY use in typical anionic formulations, and shows particular benefits of synergistic action on removal of difficult stains like oily and fatty ones from fabrics or other surfaces, even after ageing.
Cationic surfactant compatible with anionic systems.
Increases the washing ability of anionic surfactants, allowing you to remove fatty and other hardly soluble contaminants from fabrics and other surfaces (chocolate, tomato sauce, etc.).
Praepagen HY is mainly used in laundry detergents.
The input rate for washing powder is 1.5 - 2% by active substance.
Can also be used in hard surface cleaners, dishwashing detergents.
Increases detergent and foaming power at low concentrations.
Practically does not increase the washing ability of non-ionic surfactants.
40% active substance.
Characteristics of Praepagen HY:
Praepagen HY could be classified as a typical cationic surfactant whose solubility or hydrophilic characteristics are improved by the presence of a hydroxyl group in Praepagen HY structure.
This characteristic allows Praepagen HY use in typical anionic formulations, and shows particular benefits of synergistic action on removal of difficult stains like oily and fatty ones from fabrics or other surfaces, even after ageing.
Synergistic action of Praepagen HY:
Praepagen HY presents a synergistic effect when incorporated with anionic, amphoteric and/or non-ionic surfactants preferably in manual dishwashing detergents.
Labeling under GHS/CLP of Praepagen HY:
Praepagen HY is classified with H373 (May cause damage to organs through prolonged or repeated exposure if swallowed.)
This classification is negligible for the labeling of formulations containing less than 10% (active) Praepagen HY.
Standard concentrations are 1% active and below.

Use of Praepagen HY in laundry powder detergents:
Praepagen HY is a detergency booster for use in all laundry detergent powders and liquids for clothes washing in household, industrial and institutional areas.
Praepagen HY can be added in the slurry stage or can be adsorbed in zeolite, layered silicate or other inorganic material for post-dosage.
Praepagen HY is recommended to be used at a dosage of 0.5 – 1.5% (active material) in the powder detergent formulation.
The washing tests were carried out with different soils (tomato sauce, raw palm oil, curry and chocolate) and different fabrics, 100% cotton and miscellaneous CO/PES (poplin, knitting, gabardine, sheet and tergal).
To reproduce difficult spots, one chose those frequently found in day-to-day soils, mainly the ones found in children’s clothes and kitchen towels.
The exact time of aging that the soil has in practice (the time the dirt remains in the fabric until Praepagen HY is washed) was also simulated.
The tests were carried out in three types of washing equipment: Linitest, Jar test modified and top loader washing machine – Brastemp.
Certain washing conditions, such as type and concentration of detergent, washing ratio, temperature and water hardness were found to affect the washing result.
In this work, the positive influence of Praepagen HY when added to HDP can be easily observed.
The results of spot removal were observed visually, which is important bearing in mind that this is the evaluation parameter used by the consumer, in final analysis when making his choise.
Use of Praepagen HY in hard surface cleaners:
Main characteristics:
Compatible in non-ionic and anionic liquid systems, even in the presence of builders.
Can be used as detergency booster.
Advantages
Detergency increase in presence of anionic surfactants (including LAS).
Benefits observed in low concentration.
Disadvantages
Relatively high cloud point.
Usage limited by LAS concentration (narrow compatibility range) and electrolytes.
In association with non-ionic surfactants no significant benefits have been observed.
Use of Praepagen HY in disinfectant cleaners:
Praepagen HY can be used in hard surface cleaners with an excess of cationic compounds, presenting all the benefits when compared to anionic cleaners but with a special anti-bacteria effect.
