Embodiment 1

[0095] Example 1: Preparation of aminosiloxanes with polyethylene terephthalate-co-polyoxyethylene terephthalate (PET-POET) functionality

[0096] HANSA ASR 7020 (aminosilicone oil from CHT) and TexCare SRN300 (polyethylene terephthalate-co-polyoxyethylene terephthalate, M n =4900, from Clariant) were added to a single-neck round bottom flask with a magnetic stirring bar at a weight ratio of 1 / 0.025. The reaction was carried out at 165 °C and high vacuum level (~1 mbar (100 Pa)) for 180 min. The resulting product is a thick oil.

Embodiment 2

[0097] Example 2: Improved deposition due to PET-POET modification of aminosilicone

[0098] Emulsification of PET-POET modified aminosiloxane

[0099] PET-POET modified aminosiloxane prepared as described in Example 1 was used in water using a nonionic surfactant blend (Neodol 25-7 (primary alcohol ethoxylate, primary alcohol ethoxylate, ex Shell Chemicals) and Synperonic A20 (POE primary alcohol ex Croda)) emulsified. Modified aminosilicone oil (0.1 g) was added to a 14 ml capacity squat form glass tube together with 9.9 g of emulsifier solution (1% nonionic surfactant blend in deionized water), and the Shear mixer (VWR VDI12 micro homogenizer with S12N-12S appliances, setting '5') mixed for 90 seconds.

Abstract

The present invention relates to a polymer material which is a copolymer of polyethylene terephthalate and polyoxyethylene terephthalate modified by attachment of a silicone group which is covalently bonded either directly or via an optional linker group to the copolymer, to an emulsion comprising a particle comprising (a) the modified copolymer and (b) a silicone liquid, and an aqueous continuous phase, a process to make the emulsion, to a laundry composition comprising the modified polymer or emulsion, and to the use of the modified copolymer to increase silicone deposition onto fabric.

Description

technical field [0001] This invention relates to improvements in laundry compositions. More specifically, the present invention relates to polymers, emulsions comprising the polymers, and laundry compositions comprising the emulsions. Background technique [0002] Silicone oils are known to be useful in softening fabrics and have been incorporated into numerous laundry compositions. A problem with these materials is that they are expensive components but deposit inefficiently on the fabric. [0003] One way to increase the deposition of silicones is to formulate them in emulsion form using, for example, nonionic surfactants as emulsifiers. [0004] However, the problem of low deposition efficiency still exists. [0005] Therefore, there is a need to improve the efficiency of silicone deposition on fabrics. Contents of the invention [0006] In a first aspect, the present invention relates to copolymers of polyethylene terephthalate and polyethylene oxide terephthalate ...
