Embodiment 1

[0019] A neutral low-foaming laundry detergent containing optical bleach, its components and parts by mass are:

[0020]

[0021]

[0022] Above-mentioned optical bleaching agent is purchased from Ciba Company, model: BMC, sodium chloride as a thickener, disodium edetate as a chelating agent.

[0023] The preparation method of the neutral low-foaming laundry detergent containing optical bleach of embodiment 1 is as follows:

[0024] 1. Add in 76.58 parts of measured deionized water in turn, heat up to 60°C-70°C, stir while adding 6 parts of fatty alcohol polyoxyethylene ether sodium sulfate (AES), 3 parts of alkyl glucoside (APG), 2 parts of coconut Oleamidopropyl betaine (CAB), 2 parts of fatty alcohol polyoxyethylene (9) ether, 5 parts of ricinoleic acid soap, stirred to dissolve.

[0025] 2. Cool down to below 30°C, add 0.02 parts of optical bleaching agent, 3 parts of polyacrylic acid sodium salt, 0.1 part of disodium edetate, 0.1 part of essence, 0.2 parts of 2-m...

Embodiment 2

[0028] According to the same preparation method as in Example 1, the neutral low-foaming laundry detergent containing optical bleach is prepared with the following main active components and parts by mass:

[0029]

[0030]

[0031] Above-mentioned, optical bleaching agent is purchased from Ciba Company, model: BMC, sodium chloride as thickener, sodium citrate as chelating agent.

[0032] The present invention compares with performance of detergent containing hydrogen peroxide

[0033] Select Example 2 and compare the decontamination performance of commercially available hydrogen peroxide-containing laundry detergent. The coffee stained cloth whose whiteness has been measured in advance is soaked in two kinds of washing baths and exposed to the sun. After 1 hour, the coffee stain removal effect is obvious. After rinsing and drying, Then measure the whiteness of the stained cloth. The difference between the front and back whiteness reflects the decontamination ability. ...

Abstract

The invention relates to a neutral low foam laundry detergent containing an optical bleaching agent. Main active components of the laundry detergent by mass comprise a surface active agent 10-25 parts, plant oleic acid soap 1-9 parts, the optical bleaching agent 0.01-0.1 part, a chelating agent 0.1-1 part, a redeposit-resistant agent 1-5 parts and a thickening agent 0.5-5 parts. The neutral low foam laundry detergent containing the optical bleaching agent can have a great whitening effect on clothes after the clothes are washed, is neutral and free of stimulation, and produces low foam easy to rinse.

Description

technical field [0001] The invention relates to a washing agent, in particular to a neutral low-foaming laundry liquid containing an optical bleaching agent. Background technique [0002] With the rapid development of laundry detergent, the market has gradually matured, and the functionality of laundry detergent has become stronger and stronger. At present, there are two types of laundry detergent containing bleach, one is chlorine bleach containing sodium hypochlorite, and the other is oxygen bleach containing hydrogen peroxide. The latter can be used for all kinds of clothes, but the bleaching efficiency is low, the low-temperature bleaching effect is not obvious, and the amount of use is relatively large. [0003] The invention is composed of optical bleaching agent, vegetable oleic acid soap and surfactant. The liquid color is blue, and the washed clothes appear blue-white under the condition of light (action principle, light releases active oxygen for bleaching), effec...
