Description
Technical field
The invention belongs to the new opplication of the technical field of fluorescent whitening agent more particularly to cationic surfactant and support
Fluorescence cosmetics.
Background technique
Fluorescent whitening agent (fluorescent brightener) is a kind of fluorescent dye, or is white dye, is one
The complicated organic compound of kind.Its characteristic is that incident ray can be excited to generate fluorescence, and contaminated substance is made to obtain similar fluorite
Sparkling effect, the substance for seeing naked eyes are very white.
Fluorescent whitening agent is a kind of color conditioners, and it is gorgeous to have the function of that brilliant white increases, is widely used in papermaking, weaving, washing
In the multiple fields such as agent.There are about 15 kinds of basic structure types, nearly 400 kinds of structures for fluorescent whitening agent.China allows in clothes washing
There are two types of types for the fluorescent whitening agent added in agent: distyryl biphenyl class (such as CBS) and double triazine amino-stilbenes
Class (such as 33#).
Fluorescent whitening agent action principle is to absorb sightless ultraviolet light in light, and issue visible blue light, with fabric
After the yellow light of sending is overlapped, it is complementarily shaped to white light, the white light for issuing fabric increases, and can visually feel that white fabrics are bright
Aobvious to become brilliant white, here it is lightening effects.Sightless ultraviolet light can be absorbed in fluorescent whitening agent, and (wave-length coverage is about 60-
380nm), be converted to the visible light of longer wavelengths of blue light or purple, thus can compensate it is undesired yellowish in matrix, together
When reflect more visible lights than original incident wavelength in 400-600nm ranges, so that product be made to seem whiter, more
It is bright, more bright-coloured.
Fluorescent whitening agent is the organic compound of a kind of couple of human health, and human body Long Term Contact is easily carcinogenic.On the market
90 or more percent cotton wool has a fluorescer, woman monthly menstruation when, what cervix opening was open, it is attached on sanitary napkin
Fluorescent whitening agent be all seeped into vivo, at least want 7 Nian Caineng to excrete by human homergy, fluorescent whitening agent causes
Women suffers from the sick hair rate of uterine malignant tumour/cancer and improves 5--13 times, so, the sixth of the twelve Earthly Branches is forbidden to use fluorescence increasing in paper industry
White dose of manufacture food packaging wrapping paper, cotton wool and napkin paper etc..In addition, fluorescent whitening agent is not easy to be decomposed, accumulate in vivo
Body immunity can be weakened.Long-time service can cause adverse effect to skin: as skin is dark and gloomy, contact dermatitis, long acne suppurate,
Fluorescent whitening agent can destroy erythrocyte membrane after entering capillary: the risk of Yi Yinfa leukemia (leukaemia).
It is therefore desirable to eliminate fluorescent whitening agent by chemical means.However, current fluorescence cuts down the generally existing valence of agent
The defect that lattice are expensive, poorly water-soluble and dosage are big.Therefore, find it is a kind of it is charge it is strong, good water solubility, dosage is few and price is low
The honest and clean substance that can inhibit fluorescence is those skilled in the art's technical problem urgently to be resolved.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of charge strong, good water solubility, dosage are few and cheap
Fluorescent whitening agent can be inhibited to generate the substance of fluorescence.
Divide in the fluorescence for inhibiting anionic fluorescent whitening agent to generate the invention discloses cationic surfactant and answers
With.
Preferably, the cationic surfactant is cation Gemini surfactant.
Preferably, the cationic surfactant is quaternary ammonium salt cationic Gemini surface active agent, the quaternary ammonium
Shown in the chemical formula of salt form cation Gemini surfactant such as formula (1),
Wherein, R is the alkyl of C8-C12, n 2,4 or 6, X Cl-
Or Br-。

Described 4,4 '-bis- (2- sulfonic benzo vinyl) -1, shown in the chemical formula of 1 '-biphenyl such as formula (2),
The present invention provides one kind to support fluorescence cosmetics, including cationic surfactant and water.
Preferably, the cationic surfactant is quaternary ammonium salt cationic Gemini surface active agent, the quaternary ammonium
Shown in the chemical formula of salt form cation Gemini surfactant such as formula (1),
Wherein, R is the alkyl of C8-C12, n 2,4 or 6, X Cl-
Or Br-。
Preferably, the cationic surfactant is 1,2- ethylenediamine, N1, N2- dioctyl, N1, N1, N2, N2- tetra-
Methyl dichloro ammonium.
Preferably, cationic surfactant the mass percent in fluorescence cosmetics be 0.05%~
0.50%.
The present invention also provides one kind to support fluorescer, including cationic surfactant and water.
The cationic surfactant is quaternary ammonium salt cationic Gemini surface active agent, the quaternary ammonium salt cationic
Shown in the chemical formula of Gemini surface active agent such as formula (1),
Wherein, R is the alkyl of C8-C12, n 2,4 or 6, X Cl-
Or Br-。
It should be noted that when it is described support fluorescence cosmetics contain anionic fluorescent whitening agent when, anionic fluorescence
Brightening agent is 4,4 '-bis- (2- sulfonic benzo vinyl) -1,1 '-biphenyl, described 4,4 '-bis- (2- sulfonic benzo vinyl) -1,
Shown in the chemical formula of 1 '-biphenyl such as formula (2),
The quaternary ammonium salt cationic Gemini surface active agent and described 4,4 '-bis- (2- sulfonic benzo vinyl) -1,1 ' -
The molar ratio of biphenyl is (1-2): 1.
Preferably, the fluorescence cosmetics that support can be skin care item, or cosmetics.
It should be noted that 4,4 '-bis- (2- sulfonic benzo vinyl) -1,1 '-biphenyl is that common fluorescence increases on the market
White dose, with not only hydrophilic but also oleophylic attribute, oleophylic sexuality were stronger;Therefore, contain 4,4 '-bis- (2- sulphurs once having used
Acidic group styryl) -1,1 '-biphenyl facial mask or other containing 4,4 '-bis- (2- sulfonic benzo vinyl) -1,1 '-biphenyl
Cosmetics;It only needing 15 minutes, 4,4 '-bis- (2- sulfonic benzo vinyl) -1,1 '-biphenyl is just firmly adsorbed on human skin,
It is absorbed by the body, 4 to be absorbed by the body, 4 '-bis- (2- sulfonic benzo vinyl) -1,1 '-biphenyl needs to be discharged for general 7 years
In vitro.
The purpose of the present invention is big for the generally existing expensive, poorly water-soluble of the abatement agent of fluorescence in the prior art and dosage
Defect.Therefore, subject cationic surfactant point application in the fluorescence for inhibiting anionic fluorescent whitening agent to generate.
It is a discovery of the invention that cationic surfactant and anionic fluorescent whitening agent occur electrical neutralization and form precipitating, promote
So that cationic surfactant and the anionic fluorescent whitening agent is generated precipitating and does not dissolve in, so that fluorescence is lost, this hair
It is bright to also found that Gemini surface active agent has the advantages that dosage is few.Present invention discover that cationic surfactant can prepared directly
When skin care item or cosmetics, the work for the fluorescence for inhibiting anionic fluorescent whitening agent to generate can be played by being directly added into water phase
With.
