Problems solved by technology

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). Greater irritation and damage to the skin

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) The mixture of 5% C12 internal olefin sodium sulfonate and C18 internal olefin sodium sulfonate, the mixing mass ratio is 1:1, the hydroxyl body (hydroxyalkane sodium sulfonate) in the C12 internal olefin sulfonate The mass ratio of / olefin body (sodium olefin sulfonate) is 92 / 8, and the mass ratio of hydroxyl body (sodium hydroxyalkane sulfonate) / olefin body (sodium olefin sulfonate) in C18 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] Preparation of C12 Internal Olefin Sulfonate

[0030] 1-Dodecene "Linealene 12, manufactured by Idemitsu Kosan Co., Ltd." (6000 g (35.6 mol), 180 g of protic β-zeolite (CP-814E, Zeolyst Co., Ltd.) as a solid acid catalyst was added to a flask with a stirring device (3% by mass relative to the raw material α-olefin), under stirring, the reaction was carried out at 120° C. for 20 hours. Next, the crude internal olefin was transferred to a distillation flask and distilled at 124-136° C. / 7.5 mmHg. This gives an internal olefin with 12 carbon atoms having an olefin purity of 100%. The double bond distribution of the obtained internal olefin is 0.5% by mass at the C1 position, 33.1% by mass at the C2 position, 23.7% by mass at the C3 position, 21.2% by mass at the C4 position, 15.0% by mass of C5 and 6.6% by mass of C6.

Abstract

The invention discloses a laundry detergent for removing oil contamination. By combining a specific sodium sulfonate surfactant and internal-olefins sodium sulfonate, during the process for washing the oil contamination dipped in a fabric, thoroughness in washing can be realized, and the fabric is soft.

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...
