Embodiment 1

[0020] A refreshing type shampoo, which comprises the following components by weight percentage:

[0021] (1) 10% lauryl dimethyl amine oxide;

[0022] (2) 5% sodium carbonate;

[0023] (3) 0.3% phenoxyethanol;

[0024] (4) 0.3% methyl p-hydroxybenzoate;

[0025] (5) 3% C 4 f 7 CH 2 CF 2 CH 2 CH 2 SO 3 Na;

[0026] (6) 5% C18 sodium internal olefin sulfonate, the mass ratio of hydroxyl body (sodium hydroxyalkane sulfonate) / olefin body (sodium olefin sulfonate) in the sodium internal olefin sulfonate is 80 / 20;

[0027] (7) The remaining water.

preparation example

[0028] The internal olefin sulfonates are known compounds, and their typical but non-limiting preparation examples are as follows:

[0029] 7000 g (25.9 moles) of 1-octadecyl alcohol and 700 g of solid acid catalyst γ-alumina (10% by mass relative to the raw material alcohol) were added to a flask with a stirring device, and were stirred at 280° C. while The reaction was carried out for 10 hours while flowing nitrogen gas (7000 mL / min.) into the system. After the reaction, the conversion rate of alcohol was 100%, and the purity of C18 internal olefins was 98.2%. The obtained crude internal olefin was transferred to a distillation flask and distilled at 148-158° C. / 0.5 mmHg to obtain an internal olefin having 18 carbon atoms with an olefin purity of 100%. The double bond distribution of the obtained internal olefin was: 0.5% by mass at the C1 position, 25.0% by mass at the C2 position, 22.8% by mass at the C3 position, 19.1% by mass at the C4 position, 14.0% by mass at the C5 ...

Abstract

The invention discloses liquid laundry detergent capable of removing grease dirt. According to the liquid laundry detergent, a specific combination of sodium sulfonate surfactants and internal olefin sulphonates is adopted, and in the process of removing the grease dirt immersed in a fabric, washing is thorough and the fabric is soft and smooth.

Description

technical field [0001] The invention relates to a laundry detergent, in particular to a degreasing laundry detergent. Background technique [0002] Laundry liquid is a new washing substance that has emerged in recent years. Its working principle is similar to that of traditional washing powder and soap, and its active ingredients are surfactants. The difference is that traditional washing powder and soap use anionic surfactants, which are mainly sodium alkyl sulfonate and sodium stearate, and are highly alkaline (the pH of washing powder is generally greater than 12). It is more irritating and harmful to the skin. The laundry detergent mostly uses non-ionic surfactants, the pH is close to neutral, mild to the skin, and after being discharged into nature, it degrades faster than washing powder, so it has become a new generation of detergent. [0003] The active ingredients of laundry detergent are mainly non-ionic surfactants, whose structure includes hydrophilic ends and l...
