Conditioners for hair volume control with Polyquaternium-37

Hair volume control properties of formulations containing Polyquaternium-37 were investigated in

comparison to two market conditioner from the European market.

Therefore, ten hair strands (2g/15cm) per test product were treated for a volume measurement

according to shampoo or conditioner protocol. As a reference, ten hair strands were treated with

water and used as control measurements.

All 120 hair strands were wetted with tap water (38°C).

The conditioner treatment consists of a treatment 12% SLES (Sodium Laureth Sulfate (0.25g/g

hair)) for five minutes and a subsequent treatment with conditioner (0.125g/g hair) with three

minutes exposure time.

After each treatment the hair strands were rinsed with tap water (38°C).

The strands have been dried overnight on the sample holder in a flow of dry air (humidity ~18%).

Volume measurements were conducted in an automated combing system equipped with an optical

measurement system. A video of the rotating hair strand is recorded, and the volume before

combing determined. Afterwards the hair strands are combed twenty times, deionized, and the

volumes is determined again (volume after combing).

It can be clearly seen that the two formulations containing Polyquaternium-37 (formulations 2 and
3) reduce the volume of treated hair strands before and after combing compared to control (water treatment, only), conditioner formulation without Polyquaternium-37 (formulation 1) and the two conditioners from the market (also without Polyquaternium-37).

Cationic, cold processable conditioning formulations

Cosmetic formulations have to be designed to exhibit a certain viscosity to allow ease of use especially for products to be used under the shower. The viscosity of shampoo formulations containing fatty alcohol sufates or sulfated fatty alcohol ethoxylates (e.g. sodium laureth sulfate) can be easily increased by using salts like sodium chloride. This is a very simple and cost effective way. Viscosity of typical cationic formulations used for hair conditioning ("conditioners") usually cannot be increase by salt addition. Therefore the common way for thickening conditioners is to use fa...
