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% C14 internal olefin sodium sulfonate and C16 internal olefin sodium sulfonate, the mixing mass ratio is 1:1, the hydroxyl body (hydroxyalkane sodium sulfonate) / The mass ratio of olefin body (sodium olefin sulfonate) is 93 / 7, and the mass ratio of hydroxyl body (sodium hydroxyalkane sulfonate) / olefin body (sodium olefin sulfonate) in C16 internal olefin sulfonate is 88 / 12;

[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] Both the C14 internal olefin sulfonate and the C16 internal olefin sulfonate are known compounds, and their typical but non-limiting preparation examples are as follows:

[0030] Preparation of Sodium C14 Internal Olefin Sulfonate

[0031] 6000 g (26.7 moles) of 1-tetradecene "Linealene 14" (manufactured by Idemitsu Kosan Co., Ltd.) and protic β-zeolite "CP-814E" (Zeolyst) as a solid acid catalyst were placed in a flask equipped with a stirring device. 180 g (3% by mass relative to the raw material α-olefin) was reacted at 120° C. for 20 hours while stirring. Next, the crude internal olefins were transferred to a distillation flask and distilled at 124-136° C. / 7.5 mmHg to obtain internal olefins having 14 carbon atoms with an olefin purity of 100%. The double bond distribution of the obtained internal olefin was 1.3% by mass at the C1 po...

Abstract

The invention discloses a laundry liquid capable of removing oil stain. The laundry liquid is a mixture of a specific sodium sulfonate surfactant and internal olefin sodium sulfonates, and is capable of realizing complete washing and softening fabric in oil stain cleaning processes.

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...
