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) 5% C16 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 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] 7000 g (28.9 moles) of 1-hexadecanol "Kalcol 6098" (manufactured by Kao Corporation) and 700 g of γ-alumina as a solid acid catalyst (10% by mass relative to the raw material alcohol) were placed in a flask equipped with a stirring device. , the reaction was carried out at 280° C. for 5 hours with stirring while flowing nitrogen gas (7000 mL / min.) in the system. After the reaction, the conversion rate of alcohol was 100%, and the purity of C16 internal olefins was 99.7%. The obtained crude internal olefin was transferred to a distillation flask and distilled at 136-160° C. / 4.0 mmHg to obtain an internal olefin having 16 carbon atoms with an olefin purity of 100%. The double bond distribution of the obtained internal olefin was 0.7% by mass at C1 position, 16.3% by mass at C2 position, 15.1% by mass at C3 position, 15.7% by mass at C4 posi...

Abstract

The invention discloses an oil-stain-removal liquid laundry detergent. The liquid laundry detergent employs combination of a specific sodium sulfonate surfactant and sodium internal-olefin sulfonate, and realizes thorough washing and enables fabric to be flexible in the process of cleaning oil-stain-impregnated fabric.

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...
