Description
Technical field
The invention belongs to cleaning product field, particularly relate to a peptide species foaming agent, its preparation method and application.
Background technology
Foaming agent is a kind of surfactant, mainly reduces interfacial tension on gas-water interface, promotes air at material
Slurry is formed minute bubbles, expands sorting interface, and ensure that bubble rises formation froth bed.Foaming agent is typically surface activity
Agent, its molecular structure is made up of hydrophilic (oleophobic) group of nonpolar oleophylic (hydrophobic) group and polarity, is formed existing hydrophilic
Property has again so-called " amphiphilic structure " molecule of lipophilic.Foaming agent is added in water, and hydrophilic group inserts aqueous phase and lipophilic group inserts
Oil phase or setting in atmosphere, are formed at aligning on boundary layer or surface, so that interfacial tension or surface tension fall
Low.It is said that in general, the aqueous solution containing very small amount foaming agent i.e. has foaming characteristic.Common foaming agent has hydroxy compound species, ether
And ether alcohol class, pyridines and ketone.But this class foaming agent in the cosmetics time, the skin for people has stronger thorn
Swash property, and bio-toxicity is bigger, it is impossible to degraded by human body.The most this kind of foaming agent can produce considerable influence to environment, because
It is difficult to be degraded, and can affect Environmental security.
Summary of the invention
On the one hand the weak point that it is an object of the invention to overcome prior art to exist and provide a peptide species foaming
Agent, the polypeptide foaming agent foam performance of the present invention is good, and foaming abundancy is stable, has good dirt-removing power, to hard water and electrolysis
Matter tolerance is higher, recyclable regenerative, and this foaming agent can be degraded by human body, not pollutes environment simultaneously.
The technical solution used in the present invention is: a peptide species foaming agent, comprises polypeptide, the aminoacid sequence of described polypeptide by
2～4 aminoacid sequence a repeated are constituted, or are made up of 2～4 aminoacid sequence b repeated, or by aminoacid sequence a and
Aminoacid sum after aminoacid sequence b is constituted with any form of combination and combines is not more than 49, and wherein aminoacid sequence a is
LEELAEQ, aminoacid sequence b be VEELLSA, L be leucine, E is glutamic acid, and A is alanine, and Q is glutamine, and V is figured silk fabrics
Propylhomoserin, S is serine.When aminoacid sum is more than 49, the folding of protein can be affected, and then affect making of polypeptide foaming agent
Use effect.
As the further improvement to technique scheme, the aminoacid sequence of described polypeptide is by 3 aminoacid repeated
Sequence a is constituted, or is made up of 3 aminoacid sequence b repeated, or by aminoacid sequence a and aminoacid sequence b with aba form
Combination is constituted.The polypeptide foaming agent using effect so obtained more preferably, can form the foam of more horn of plenty, simultaneously relative to it
The polypeptide foaming agent of his combination, the retention time of foam is longer.
As the further improvement to technique scheme, described polypeptide is dispersed in water or buffer solution.
