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% C14 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 93 / 7;

[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] In a flask equipped with a stirring device, 6000 g (26.7 mol) of 1-tetradecene "Linealene14" (manufactured by Idemitsu Kosan Co., Ltd.) and a protic β-zeolite "CP-814E" (Zeolyst) as a solid acid catalyst were added 180 g (3% by mass relative to the raw material α-olefin) was reacted at 120°C for 20 hours with stirring. Next, the crude internal olefin was transferred to a distillation flask and distilled at 124-136°C / 7.5 mmHg to obtain an internal olefin with a carbon number of 14 and an olefin purity of 100%. The obtained internal olefin has a double bond distribution of 1.3% by mass at C1 position, 31.8% by mass at C2 position, 23.8% by mass at C3 position, 21.0% by mass at C4 position, 8.6% by mass at C5 position, and 13.6% by mass in total of C6 and 7 positions. .

[0030] The internal olefin with 14 carbon atoms is added to a thin-film sulfo...

Abstract

The invention discloses a laundry liquid for removing oil stains. The laundry liquid employs a specific combination of a sodium sulfonate surfactant and sodium internal olefin sulfonate, and can clean dipped oil stains in fabric; the washing is thorough and the fabric is soft.

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...
