Features & Benefits+
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 its structure. This characteristic allow its 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.
Praepagen HY presents a synergistic effect when incorporated with anionic, amphoteric and/or non-ionic surfactants preferably in manual dishwashing detergents.
Applications & Uses+
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 it 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 choice.
Use of Praepagen HY in hard surface cleaners
Compatible in non-ionic and anionic liquid systems, even in the presence of builders. Can be used as detergency booster.
Detergency increase in presence of anionic surfactants (including LAS). Benefits observed in low concentration.
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 dishwashing detergents
High water solubility. Good compatibility with anionic, non-ionic and amphoteric surfactants. High stability at low and high temperatures. Good degreasing effect.
Detergency increase in presence of anionic surfactants (including LAS). High viscosity increment using small quantity of electrolyte (NaCl). Foam improvement, sometimes with stabilization effect.
Narrow compatibility range with LAS. Can cause skin irritation when used at higher concentrations.

Storage & Handling+
Praepagen HY can be stored for at least 12 months in original sealed containers at room temperature under the recommended conditions.
Protect from exposure to cold during transport and storage. The properties of Praepagen HY are reversibly altered by exposure to cold. If Praepagen HY becomes turbid, thickens or freezes through exposure to cold, thaw slowly at room temperature and afterwards stir briefly.
