Read the results in 15 minutes. A strong positive results may show within 15 minute.
But the negative result must be reported after 15 minutes. And the results after 20 minutes are not valid anymore.
The lab indicated that the recombinant protein of Indian mutant (B.1.617.2),
A.23.1(Unit Kingdom), AT.1 (Russia), B.1.1.7(Unit Kingdom), B.1.351 (South Africa),
B.1.616 (France), B.1.621 (Colombia), C.36 (Egypt), C.37 (Peru), P.1 (Japan/Brazil),
P.2 (Brazil) can be detected by Jinwofu SARS-CoV-2 Antigen Test Kit.
For the newly descovered mutant Omicron(B.1.1.529), we performed sequence
alignment analysis on its mutation sites, and found that all the mutation sites were
outside the epitope region recognized by the monoclonal antibody selected by our company.
By bioinformatics analysis, Jinwofu SARS-CoV-2 Antigen Test Kit can also effectively detect
mutant Omicron(B.1.1529)

Phenol is an organic compound with C6H5OH. It is a colorless needle -shaped crystal with a special smell. It is toxic and is an important raw material for producing certain resins, sterilization agents, preservatives, and drugs (such as aspirin). It can also be used for the treatment of sterilized surgical equipment and excrement, skin sterilization, itching and otitis media. The melting point is 43 �° C, which is slightly soluble at water at normal temperature, and is easily soluble in organic solvents.
When the temperature is higher than 65 �° C, it can solve the water in any proportion. The phenol is corrosive. After contact, the local protein degenerates. The solution can be washed with alcohol with alcohol. A small part of the phenol is exposed to the air by oxidation into pink. When the three -price iron ion becomes purple, this method is usually used to test the phenol.

GERMALL PLUS is a combination of Diazolidinyl Urea and IPBC pre-dissolved in Propylene Glycol for ease of use. This combination exhibits a synergistic preservative effect, which reduces the total active preservative level necessary; provides for complete, broad spectrum preservation against Gram-positive and Gram-negative bacteria, yeast, and mold.
Compatible with most cosmetic raw materials.
Can be used in a wide variety of leave-on and rinse-off personal care formulations for reliable preservation.
Recommended use levels in a finished formulation is 0.1-0.5%.
Add at 50�°C or below during the cool down stage of processing.
Every cosmetic formulation requires a specific preservative system to meet its individual needs. Therefore, every newly developed or modified product should be challenge tested to assure preservative efficacy.

3. It served as an anti-oxidant agent with better performance, which is better than VE/VC/BHT
4. It is easily dissolved with dissolvability of 1% in glycol and easy to be added. Meanwhile it has better stability and security.
5. Dosage: 0.1-1.0%
2-Ethylhexyl Salicylate, or octyl salicylate, is an organic compound used as an ingredient in sunscreens and cosmetics to absorb UVB (ultraviolet) rays from the sun. It is an ester formed by the condensation of salicylic acid with 2-ethylhexanol. It is a colorless oily liquid with a slight floral odor.
The salicylate portion of the molecule absorbs ultraviolet light, protecting skin from the harmful effects of exposure to sunlight. The ethylhexanol portion is a fatty alcohol, adding emollient and oil-like (water resistant) properties.

Application
Isopropyl myristate (IPM) is a fatty acid ester which is used as solvent in water-in-oil emulsion, oils and fatty based ointments. The use of IPM is recommended in the Sterility Test chapter of the European, Japanese and United States Pharmacopoeia (EP, 2.6.13, JP, 4.06 and USP, 71) as diluent for oils and oily solutions, as well as for ointments and creams. Indeed, its solvent properties improve the filterability of these samples.
Isopropyl myristate is known as a penetration enhancer for topical preparations. It is a water clear, low viscous oily liquid with a very good spreading capacity on the skin. Isopropyl Myristate is mainly used in cosmetics as an oil component for emulsions, bath oils and as a solvent for active substances.
