Description

A kind of containing N-lauroyl-ALANINE sodium salt or the potassium salt bath gel as surfactant

Technical field

The present invention relates to a kind of bath gel, especially a kind of containing N-lauroyl-ALANINE sodium salt or potassium salt as the bath gel of surfactant, belong to hair shampoo article technical field.

Background technology

In bath gel, need to use surfactant, common surfactant, although because of have good characteristic be widely used in produce, life in, its biological degradability and eco-compatibility poor, can work the mischief to ecological environment.Along with people more and more pay close attention to the safety of various product, mildness and the raising to environmental protection requirement, study and develop multi-functional high-quality environmental friendliness surfactant oneself becomes the Main way of Surfactant Industry.

Amino acid type surfactant is the surfactant based on biological substance, owing to having amino acid backbone in molecule, except having other series of surfactants performances concurrently, also there are some functions of other uniqueness, if any fungistatic effect, good biocompatibility, degrades safety quick.

Amino acid classes has kind more than 200, can be used for synthesizing just tens kinds of primary amino acids wherein of N-acyl amino acid surfactant at present, as long as there is sarcosine in existing market for the conventional aminoacid of cosmetics synthesis N-lauroyl amino acid surfactant and salt thereof, glutamic acid, serine, lysine, leucine etc., reach a climax from 20th century its application and research of century 70, oneself obtains extensive use to current the type product abroad, the more influential Hamposyl having the U.S., the Medialan of Germany, the products such as the Amisoft of Japan, produce also immature in China, main dependence on import in demand, expensive, constrain the development of domestic bath gel etc.

Summary of the invention

The present invention seeks to propose a kind of containing N-lauroyl-ALANINE sodium salt or the potassium salt bath gel as surfactant to overcome the deficiencies in the prior art.

For achieving the above object, the technical solution used in the present invention is: a kind of containing N-lauroyl-ALANINE sodium salt or the potassium salt bath gel as surfactant, it, relative to the percentage ratio of its quality, comprises:

N-lauroyl-ALANINE sodium salt or potassium salt, 10%-20%;

Cocos nucifera oil acyl Kaglutam, 1.0%-5.0%;

LAA, 1.0%-3.0%;

Cocoalkyl-betanin, 1.0%-5.0%;

The solution of 50% pyridine alkane keto carboxylic acid sodium, 1.0%-3.0%;

Glycerol monolaurate, 1.0%-2.0%;

Water, 70%-80%;

Hydrolysis hyaluronic acid, 0.1%-0.5%;

Phenoxyethanol, benzoic acid, dehydroactic acid (and) Sensiva SC50,1.0%-3.0%;

Propylene glycol, water (and) nettle extract, 1.0%-3.0%;

Spice, 1.0%-2.0%;

Citric acid is appropriate, makes product keep DI-I value 5.5-6.5.

Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:

Of the present invention containing N-lauroyl-ALANINE sodium salt or the potassium salt bath gel as surfactant; Have the following advantages:

1, dirt-removing power is strong

Long-chain fatty acid and natural amino acid form amido link to be had novel molecule and independently fills performance, about chelating being formed with a lot of molecule, strange selection chelating oil molecule is selected in oil water mixture, there is very strong dirt-removing power, and the dirt-removing power of N-lauroyl-ALANINE sodium salt is more better than N-lauroyl-Pidolidone disodium and N-lauroyl-L-sodium sarcosinate, can separately as cleansing.

2, there is the good compatibility

Articles for washing containing N-lauroyl-ALANINE natrium surfactant, the sense of touch when washing and after washing is all good, and skin can not be too dry and astringent and have tender sense of touch.

3, environmental protection

Its biological degradability of common surfactant and eco-compatibility poor, can work the mischief to ecological environment, its catabolite of N-lauroyl-ALANINE is that aminoacid and fatty acid almost do not affect environment.

4, little to the zest of skin

Emphasize oiliness skin or the special Cleansing Foam of male at present, the most frequently used cleansing is sodium lauryl sulphate, because being the extremely strong surfactant of degrease power for this reason, but it has potential zest to skin and descends rice to reduce making the defence capability of skin self for a long time, causes the phenomenon such as dermatitis, skin aging.Long-chain fatty acid before N-lauroyl-Pidolidone natrium surfactant is similar to dodecyl, there is same dirt-removing power, but because it is adopt natural component be raw material manufacture and obtain, composition itself can be adjusted to about faintly acid PH6.5-7, so very little to skin irritation, life-time service, misgivings can not be needed to have injury to skin, and anemia of pregnant woman and infant product are suitable for too.

5, cost is low

N-lauroyl-ALANINE belongs to ammonia propylhomoserin type surfactant, and on existing market, such surfactant is used for superior cosmetics, this is on the one hand because the pH value of this kind of surfactant and skin is close, nontoxic non-stimulated to skin, also because production cost is high, purity is low.And the production technology of N-lauroyl-ALANINE is simple and easy to get, the high purity product being greater than 98% can be prepared, the domestic vast demand to the type surfactant can be met.
