Facial cleanser containing mixed surfactant and preparation method of facial cleanser

Abstract

The invention relates to a facial cleanser containing a mixed surfactant and a preparation method of the facial cleanser. The facial cleanser is prepared from the following components in parts by weight: 20-40 parts of fatty acid, 10-30 parts of polyhydric alcohols, 1-6 parts of a nonionic surfactant, 5-8 parts of alkali, 0.3-1.5 parts of emulsifier, 0.5-2 parts of a thickener, 2-20 parts of the mixed surfactant, 0.02-0.08 part of a chelating agent, and 18-45 parts of water, wherein the nonionic surfactant is a composition formed by PEG/PPG-25/30 copolymer and PEG-6, and the mixed surfactant is a composition formed by PEG-6, polyquaternium-43 and PEG/PPG-300/55 copolymer. The facial cleanser is rapid in foaming, has rich, smooth and elastic foam, has good moistening property and good moisture retention, has no stimulation, can be easily cleaned after washing, has very good stability, has heat resistance, and is uniform and stable at 48 DEG C, and after temperature returning, the cream is fine and uniform.

Description

technical field [0001] The invention relates to the field of daily chemicals, in particular to a facial cleanser containing a surfactant compounded by a cationic polymer and a nonionic polymer and a preparation method thereof. Background technique [0002] Soap-based facial cleanser is popular with consumers due to its strong cleaning power, refreshing and non-greasy after washing. However, due to the high pH of soap-based facial cleanser, the degreasing power will be lower than that of surfactant-based facial cleanser. The degreasing power is much stronger, which can easily lead to problems such as tightness and dryness after washing. Long-term use of products with strong degreasing power will damage the skin. Therefore, the skin feel after soap-based facial cleanser is an important issue of soap-based facial cleanser. [0003] Soap-based facial cleanser is prepared by neutralizing fatty acid and alkali, and the amount of fatty acid will affect the stability of the produc...

Problems solved by technology

However, many facial cleansers on the market can only pass the temperature of 45°C.

[0005] The foam structure of soap-based facial cleanser is relatively delicate, but it is not smooth enough to be skin-friendly and elastic. The general soap-based facial cleanser achieves the effect of increasing foam and stabilizing foam by adding surfactants, but it only relies on fatty acids to compound ordinary surface active The foaming and stabilizing effect of the agent is not obvious, and even mild surfactants will be introduced to irritate the skin, affecting the skin feeling after washing, as well as the appearance and stability of the paste
