Embodiment 1

[0047] In the first step, put 30kg of APG0810 in a stainless steel or enamel kettle with mechanical stirring, add 20kg of deionized water, heat to 50°C while stirring, and keep stirring at this temperature for about 0.5 hours.

[0048] In the second step, add 40kg of SOE-N and 10kg of SNS-80 to the above-mentioned stirred tank, and stir at a constant temperature of 50°C for about 2 hours until uniform.

[0049] In the third step, the stirring is stopped, and the mixture is allowed to stand at room temperature in the stirred tank for 4 hours, and the surfactant composition containing the alkyl glycoside is obtained after the foam subsides.

[0050] According to above-mentioned proportioning, the content of the surfactant of embodiment 1 is 62%. The surfactant composition containing alkyl glucoside contains not only surfactant, but also water, 62% is the proportion of the total mass of surfactant in the composition, on the one hand, it reflects its high concentration, and the su...

[0052] In the first step, put 20kg APG0810 and 5kg APG1214 in a stainless steel kettle or enamel kettle with mechanical stirring, add 27.5kg deionized water at the same time, heat to 60°C while stirring, and keep stirring at this temperature for about 1 hour .

[0053] In the second step, add 42.5kg NOE-C and 5kg FMEE-68 into the above stirred tank, and stir at 60°C for about 3 hours until uniform.

[0054] In the third step, the stirring is stopped, and the mixture is allowed to stand at room temperature in the stirred tank for 6 hours, and the surfactant composition containing the alkyl glycoside is obtained after the foam subsides.

[0055] According to above-mentioned proportioning, the content of the surfactant of embodiment 2 is 60%.

Embodiment 3

[0057] In the first step, put 15kg APG0810 and 10kg APG1214 in a stainless steel or enamel kettle with mechanical stirring, add 30kg of deionized water at the same time, heat to 70°C while stirring, and continue stirring at this temperature for about 3 hours.

[0058] In the second step, add 45kg of SOE-C to the above stirred tank, and stir at a constant temperature of 70°C for about 3 hours until uniform.

[0059] In the third step, the stirring is stopped, and the mixture is allowed to stand at room temperature in the stirred tank for 6 hours, and the surfactant composition containing the alkyl glycoside is obtained after the foam subsides.

[0060] According to above-mentioned proportioning, the content of the surfactant of embodiment 3 is 57.5%.

Abstract

The invention discloses a surfactant composition containing alkyl glycoside, which is prepared from the following components in parts by weight: 20-60 parts of alkyl glycoside, 10-60 parts of oil-based surfactant, deionized water 10-60 parts; The oil-based surfactant is at least selected from natural oil ethoxylate, fatty acid methyl ester ethoxylate, modified oil ethoxylate, modified oil ethoxylate sulfonate A sort of. The surfactant composition containing alkyl glycosides provided by the present invention combines green, non-toxic, easily biodegradable alkyl glycosides with novel mild oil-based surfactants, and the resulting composition is more effective than traditional surfactants It has higher safety and skin-friendliness, and the composition has good low-temperature fluidity, low foam and easy rinsing, and is suitable as the basic raw material of concentrated liquid detergent.

Description

technical field [0001] The invention belongs to the technical field of surfactant preparation, and in particular relates to a surfactant composition containing an alkyl glycoside and a preparation method thereof. Background technique [0002] Alkyl glycosides are green, non-toxic, and extremely low-irritant surfactants produced by the dehydration condensation reaction of plant-derived fatty alcohols and medical-grade glucose. The foam produced by alkyl glycosides with a hydrophobic carbon chain of 8-14 is delicate, has strong wetting power, good skin affinity, and is easy to dissolve in water without cloud point. It can be used as laundry detergent, hand sanitizer, body soap, and meal detergent The main raw material of many kinds of toiletries. For example, CN108524358A discloses a hand sanitizer for anti-inflammatory skin care and its preparation method and application, using alkyl glycoside as the main surfactant; CN108179073A discloses a mild and bactericidal laundry det...
