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 its structure.
This characteristic makes possible Praepagen HY’s 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.
2. 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 otherinorganic material for post-dosage.
Praepagen HY isrecommended 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 choise.
3. Use of Praepagen HY in hard surface cleaners:
Main characteristics of Praepagen HY:
Praepagen HY is compatible in non-ionic and anionic liquid systems, even in the presence of builders.
Praepagen HY can be used as detergency booster.

Detergency increase in presence of anionic surfactants (including LAS).
Praepagen HY benefits observed in low concentration.
Disadvantages of Praepagen HY:
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.
