What is precious to you?

Improve the cleaning performance

of your formulationsby applying it exactly where needed, keeping it there for

longer and minimizing flow on vertical surfaces .

Improve the safety

of your formulationsby avoiding splashes and leaking.

Improve the way your formulations

are perceived by consumersby increasing viscosity — consumers associate viscosity with

high concentration and performance.

Technical challenges

Hostagel PH1

Highly acidic formulations are usually

difficult to thicken

Leading cleaners contain high amounts of acids as main agent in up to 10% active

Co-acids may be present to

deliver additional benefits

Most acidic cleaners show a viscosity of about

1000-2000 mPas at room temperature

9 Hostagel PH1

Hostagel® PH1Efficient thickener for acidic formulations

Hostagel PH1 application concentrations of 2–3% active is consistent with the market average

(1.8 – 4.0%) and easily allows the adjustment to customer needs (concentration, viscosity target,

sheer & storage stability e.g. in presence of amine oxides)

Additional use of amine oxides furthermore increase detergency and controlled foam formation

of the end-product

Reduce the formulation costs due to lower active content as the viscosity can be raised through

higher acid levels

Improved convenience: Hostagel PH1 combines detergency properties with rheology modification

in one formula

Ease of use:

89%-surfactant blend of quaternary ammonium salt and ethoxylated fatty amine containing

propylene glycol (1,2-propandiol) and IPA; a slightly viscous liquid at room temperature

4 easy steps to formulate a high performance

toilet cleaner

I) add Hostagel PH1

II) add water under stirring,

Dissolve (10-30 min)

III) add Co-acids or amine

oxides or other additives

and homogenize

IV) add HCl under stirring

for viscosity to build up

toilet cleaner with high anti

limescale performance and anti disinfectant claim

Summary

▪ 2% tel quel Hostagel PH1 are sufficient to yield the (market) target

viscosity between 1000–2000 mPas

▪ Hostagel PH1 provides more initial viscosity at comparable raw material costs

▪ Use of amine oxide increases the detergency, provides foam and helps to stabilize color and viscosity

▪ A wide range of organic and inorganic acids can efficiently be thickened in presence of Hostagel PH1 allowing for tailor-made end-formulations

▪ Less acidic bathroom cleaners can be formulated using acetic acid or citric acid together with Hostagel PH1 in presence of sodium chloride

▪ Elevated sensitivity on sheer stress allows for easy processing and filling of Hostagel PH1 during production

▪ Hostagel PH1 provides excellent viscosity during the whole product life

cycle of a toilet bowl cleaner (three month) providing lasting viscosity for at least one year.
