Abstract

Provided herein is a formulation containing a PPG/PEG block-copolymer (I) on average having PEG-blocks in the range of 37-45 terminated on both sides with on average in the range of 6-11 PPG blocks. The PPG/PEG block-copolymer can be end capped with hydrocarbon systems like for example n-butyl. The PPG/PEG block-copolymer (I) is chosen to have a DSC-melting point according to DIN ISO 11357 in the range of 15-37° C. to provide for a cool touch effect and can be applied without encapsulation. Furthermore uses of such a formulation and textiles treated with such a formulation are proposed.
