Abstract
The invention discloses a hand cleanser with N-lauroyl-L-alanine sodium salt or potassium salt as a surfactant, which comprises the following components by mass: 10%-20% of N-lauroyl-L-alanine sodium salt or potassium salt; 1.0%-2.0% of polyglycerol-10 monolaurate; 2.0%-5.0% of diglycerol; 75%-85% of water; 0.5%-1.0% of essence; and the balance of bactericides. The invention has the following advantages of: strong decontamination capability, very good compatibility, green and environmental protection, less skin irritation, and low cost.
Description
Technical field
The present invention relates to a kind of handwashing liquid, especially a kind of N-lauroyl-ALANINE sodium salt or potassium salt of containing belongs to the hair shampoo article technical field as the handwashing liquid of surfactant.
Background technology
In handwashing liquid, need to use surfactant, common surfactant, although be widely used in production, life because having good characteristic, its biological degradability and eco-compatibility are poor, can work the mischief to ecological environment.More and more pay close attention to the safety of various product along with people, mildness and to the raising of environmental protection requirement, oneself becomes the main direction of Surfactant Industry to study and develop multi-functional high-quality environmental friendliness surfactant.
Amino acid type surfactant is take the surfactant of biological substance as the basis, owing to having amino acid backbone in molecule, except having other series of surfactants performances concurrently, some functions that also have other uniqueness, if any fungistatic effect, good biocompatibility is degraded safety quick etc.
the aminoacid kind has kind more than 200, just wherein the tens kinds of primary amino acids that can be used at present synthetic N-acylamino acid surfactant, as long as be used for the synthetic N-lauroyl amino acid surfactant of cosmetics aminoacid and salt thereof commonly used on existing market, sarcosine is arranged, glutamic acid, serine, lysine, leucine etc., from 20th century its application and research of century 70 reach a climax, oneself gets extensive use to the type product abroad at present, the more influential Hamposyl that the U.S. is arranged, the Medialan of Germany, the products such as Amisoft of Japan, produce in China that is that all right ripe, main dependence on import on demand, expensive, restricted the development of domestic handwashing liquid etc.
Summary of the invention
The present invention seeks to have proposed in order to overcome the deficiencies in the prior art a kind of N-of containing lauroyl-ALANINE sodium salt or potassium salt as the handwashing liquid of surfactant.
For achieving the above object, the technical solution used in the present invention is: a kind of N-lauroyl-ALANINE sodium salt or potassium salt of containing is as the handwashing liquid of surfactant, and it comprises with respect to the percentage ratio of its quality:
N-lauroyl-ALANINE sodium salt or potassium salt, 10%-20%;
Mono laurate ten polyglycerin ester, 1.0%-2.0%;
Two glycerol, 2.0%-5.0%;
Water, 75%-85%;
Essence, 0.5%-1.0%;
All the other are antibacterial.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
N-lauroyl-ALANINE sodium salt or the potassium salt of containing of the present invention is as the handwashing liquid of surfactant; Have the following advantages:
1, dirt-removing power is strong
Long-chain fatty acid and natural amino acid formation amido link have novel molecule and independently fill performance, can form about chelating with a lot of molecules, select strange selection chelating oil molecule in oil water mixture, very strong dirt-removing power is arranged, and the dirt-removing power of N-lauroyl-ALANINE sodium salt more is better than N-lauroyl-Pidolidone disodium and N-lauroyl-L-sodium sarcosinate, can be separately as cleansing.
2, has the good compatibility
Contain the articles for washing of N-lauroyl-ALANINE natrium surfactant, the sense of touch when washing and after washing is all good, and skin can be too not dry and astringent and tender sense of touch arranged.
3, environmental protection
Its biological degradability of common surfactant and eco-compatibility are poor, can work the mischief to ecological environment, and its catabolite of N-lauroyl-ALANINE is that aminoacid and fatty acid almost do not affect environment.
4, the zest to skin is little
Emphasize at present the Cleansing Foam of oiliness skin or male's special use, the most frequently used cleansing is sodium lauryl sulphate, because this is the extremely strong surfactant of degrease power, but it has the lower meter defence capability reduction that will make skin self for a long time of potential zest to skin, causes the phenomenons such as dermatitis, skin aging.The long-chain fatty acid of N-lauroyl-Pidolidone natrium surfactant front is similar to dodecyl, has same dirt-removing power, but because it is that to adopt natural component be that the raw material manufacturing gets, composition itself can be adjusted to faintly acid PH6.5-7 left and right, so very little to skin irritation, life-time service, can not need worrying has injury to skin, and anemia of pregnant woman and infant product are applicable 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 class 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, and can prepare the high purity product greater than 98%, can satisfy domestic vast demand to the type surfactant.
