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 shampoo, which comprises the following components by weight percentage:

[0021] (1) 10% dodecyl 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% C12 sodium internal olefin sulfonate, the mass ratio of hydroxyl body (sodium hydroxyalkane sulfonate) / alkene body (sodium olefin sulfonate) in the sodium internal olefin sulfonate is 92 / 8;

[0027] (7) The remaining amount of water.

preparation example

[0028] The internal olefin sulfonate is a known compound, and its typical but non-limiting preparation examples are as follows:

[0029] Into a flask equipped with a stirring device, 1-dodecene "Linealene 12, manufactured by Idemitsu Kosan Co., Ltd." (6000 g (35.6 mol), 180 g of protic β-zeolite (CP-814E, Zeolyst) as a solid acid catalyst was added (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 the distillation flask and distilled at 124-136°C / 7.5mmHg. This yields an internal olefin with a carbon number of 12 and an olefin purity of 100%. The resulting internal olefin has a double bond distribution of 0.5% by mass at the C1 position, 33.1% by mass at the C2 position, 23.7% by mass at the C3 position, and 21.2% by mass at the C4 position. The C5 position is 15.0% by mass, and the C6 position is 6.6% by mass.

[0030] The internal olefin with 12 carbon atoms is...

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 a degreasing laundry detergent. Background technique [0002] Laundry detergent is a new washing substance in recent years. Its working principle is similar to traditional washing powder and soap, and the active ingredients are all surfactants. The difference is: traditional washing powder, soap uses anionic surfactants, mainly sodium alkane sulfonate and sodium stearate, with strong alkalinity (washing powder PH is generally greater than 12), and then in use Great irritation and damage to the skin. Laundry liquids mostly use non-ionic surfactants, which have a pH close to neutral and are mild to the skin. After being discharged into nature, they degrade faster than washing powder, so they have become a new generation of detergents. [0003] The active ingredients of laundry detergent are mainly non-ionic surfactants, and its structure includes a hydrophilic end and a lipophilic end. The lipophilic...
