Problems solved by technology

In liquid detergent formulations containing partly water, TAED will undergo hydrolysis and lose its effectiveness as a detergent active because TAED reacts to form N,N' diacetylethylenediamine (DAED), which cannot act as a detergent active take effect
Therefore, TAED is not ideal as an active in aqueous detergent formulations when used without modification

[0015] Materials and Example Preparation

[0016] Material

[0017] TAED solids were purchased from Sigma-Aldrich, and TAED solids were ground to a powder using an 80 μm sieve. POLYOX water soluble resins WSR N-3000, WSR N-10 and WSR-205 were purchased from The Dow Chemical Company. WSR N-3000 and WSR N10 were each dissolved in deionized water at a concentration of 7 wt%, while WSR-205 was dissolved in deionized water at a concentration of 5 wt%. A 35% polyacrylic acid (PAA) solution with a weight average molecular weight of 250,000 was purchased from Sigma-Aldrich. Methylcellulose (MC) with a number average molecular weight (Mn) of 40K was obtained from Sigma-Aldrich and dissolved in deionized (DI) water at room temperature at 2.5% by weight.

Abstract

A detergent additive comprises an active comprising one or both of tetraacetylethylenediamine, triacetylethylenediamine; and an interpolymer complex, the interpolymer complex comprising both a proton-accepting-(co)polymer and a proton-donating (co)polymer.

Description

Background technique [0001] Textiles, such as wearable fabrics, are typically laundered by contacting the textile with a detergent formulation that is a combination of detergent components and other optional actives such as bleach. For ease of use, many users of detergent formulations prefer all-in-one products that incorporate detergent and optional actives into a single product. Additionally, many users prefer this product as a liquid rather than a solid or granular product. [0002] One common detergent active is tetraacetylethylenediamine (TAED). TAED acts as a peroxygen bleach activator and microbial control agent. TAED has been widely used in solid detergent products. In liquid detergent formulations containing partly water, TAED will undergo hydrolysis and lose its effectiveness as a detergent active because TAED reacts to form N,N' diacetylethylenediamine (DAED), which cannot act as a detergent active take effect. Therefore, when used without modification, TAED is...
