Embodiment 1

[0084] Example 1 Improved fabric softening as a result of emulsifying aminosilicone oil using PET-POET polymer

[0085] Synthesis of polyethylene terephthalate-co-polyoxyethylene terephthalate copolymer (PET-POET).

[0086] PET-18000 was polyethylene terephthalate (Mn = 18,000) from Shanghai Lianji Synthetic Fiber Company; polyethylene glycol 20,000 (Mn = 20,000) was purchased from Fluka; antimony oxide (Sb 2 o 3 ), calcium acetate and 2,6-di-tert-butyl-4-methylphenol (DBMP) were supplied from Sinopharm Chemical Reagent Co., Ltd. All reagents were used as received without further purification. The PET-POET samples were prepared using a stainless steel reactor that provided mechanical agitation, good thermal control, and high vacuum. The reactor was provided by Weihai Auto-control Reaction Kettle Ltd.

[0087] 80 g of PEG with a molecular weight of 20,000 and 5 g of PET-18000 were used for transesterification polymerization. Sb 2 o 3 (20mg) and calcium acetate (20mg) wer...

Abstract

The present invention relates to an emulsion comprising a particle comprising a copolymer of polyethylene terephthalate and polyoxyethylene terephthalate and a silicone liquid and an aqueous continuous phase, a process to make the emulsion, to a laundry composition comprising the emulsion, and to the use of the 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 emulsions and laundry compositions comprising such 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 an emulsion comprising:- [0007] (a) particles comprising a copolymer of polyethylene terephthalate and polyet...
