339 results about "Skin sensitization" patented technology

Skin sensitization, n an allergic reaction to a particular irritant that results in the development of skin inflammation and itchiness. Unlike skin irritation, the skin becomes increasingly reactive to the substance as a result of subsequent exposures.

In-vitro evaluation cell model of skin sensitization of compound and construction method of cell model

The invention discloses an in-vitro evaluation cell model of skin sensitization of a compound and a construction method of the cell model. The construction method of the cell model comprises the following steps of: designing and constructing an sgRNA (small guide ribonucleic acid) expression vector with CRISPR / Cas9 (clustered regularly interspaced short palindromic repeats / CRISPR associated protein 9), designing and constructing a homologous recombinant vector capable of knocking a reporter gene connected with a spontaneous lysis peptide sequence into an expression cassette of an HMOX1 (heme oxygenase (decycling) 1) gene, and cotransfecting a cell with the homologous recombinant vector, hCas9 (humanized Cas9) plasmid and the sgRNA expression vector for monoclone enlarging culture to form the cell model. The HaCaT cell model with a luciferase gene knocked in before a termination codon of the HMOX1 gene by a combined CRISPR / CAS9 cell monoclone technology. The cell model achieves synchronous expression of the luciferase gene and the HMOX1 gene, so that a sensitization compound and a non-sensitization compound are effectively differentiated, and the more specific and sensitive cell model is provided for compound sensitization studies.

Plant compound preservative and acne removal skincare product

The invention discloses a plant compound preservative. The plant compound preservative is prepared from, by weight, 1-20 parts of a plant root extractive, 1-20 parts of a plant flower extractive, 10-30 parts of a plant leaf extractive and 1-10 parts of plant bark extractive. The plant root extractive is obtained by mixing and extracting 1-5 parts of scutellaria baicalensis, 0.1-1 part of radix sophorae flavescentis, 0.1-1 part of moss, 1-5 parts of cordate houttuynia and 1-5 parts of Chinese herbaceous peony. The plant flower extractive is obtained by mixing and extracting 5-10 parts of calendula, 1-10 parts of hibiscus mutabilis and 1-10 parts of honeysuckle. The plant leaf extractive is obtained by mixing and extracting 1-10 parts of lotus leaves, 5-10 parts of ginkgo leaves, 2-5 parts of rosemary leaves, 1-5 parts of olive leaves and 5-10 parts of perilla leaves. The plant bark extractive is obtained by mixing and extracting 5-10 parts of shaddock peel and 1-5 parts of cinnamon. The invention further discloses an acne removal skincare product containing the plant compound preservative. The plant compound preservative can effectively inhibit growth of microorganisms such as germs and fungi in skincare product, can prolong the service life of the skincare product and has the advantages of being free of toxicity or simulation or skin sensibility or the like.

The invention relates to a preparation method of a placenta sub-totipotential stem cell active factor for beauty and skin care. The preparation method comprises the steps of separating and culturing placenta sub-totipotential stem cells and preparing the active factor. The preparation of the active factor comprises the steps of taking P3 generation placenta sub-totipotential stem cells, carrying out inoculation and digestion, carrying out ice ultrasonic cell breakage, and collecting supernatant; then, dropping in trichloroacetic acid, performing an ice bath, carrying out low-temperature centrifugation, and abandoning the supernatant; adding precooling acetone to wash sediment, conducting low-temperature centrifugation, abandoning the acetone, resuspending the sediment, and conducting filtering the product with a filter film of which the thickness is 0.1 micrometer, wherein the concentrations of the obtained SCF, a FGF, VEGF, EGF, and KGF are all larger than 20000 pg/ml. The preparationmethod of the placenta sub-totipotential stem cell active factor for beauty and skin care adopts a culture system free of heterologous animal serum, and reduces the risks of introducing heterologousanimal viruses; at the same time, there is no hormone at all in the culture system, so that possible skin allergic reaction caused by the hormones is avoided; the active factor is prepared by the adoption of the low-temperature precipitation method, so that the activity of the active factor is guaranteed.

Dogskin plaster and technique of preparing the same

The invention provides a dog-skin plaster and a preparation technique thereof. The dog-skin plaster is made from a substrate and raw herbal materials of black-plaster dog-skin plasters. The mass ratio of the raw herbal materials is the same as the mass ratio in the prescription of the black-plaster dog-skin plaster. A processed radix aconiti replaces an unprocessed radix aconiti, and a processed kusnezoff monkshood root replaces an unprocessed kusnezoff monkshood root, wherein no lead is contained. The preparation uses an ethanol extracting technology and a volatile-oil extracting technique to replace the extracting technology of frying vegetable oil in the original preparation, which can completely extract drug ingredients, without such disadvantages as drug ingredients being easily destroyed by high temperature and air pollution which are generated by the extracting technique of frying vegetable in the original preparation; the new substrate replaces the original black-plaster substrate, which has the advantages of larger drug quantity, easy putting up and off, good compatibility, release property and skin penetration property, without toxic lead content. The unprocessed radix aconiti and the unprocessed kusnezoff monkshood root in the original prescription are replaced respectively by the processed radix aconiti and the processed kusnezoff monkshood root, thus ensuring the effectiveness and safety of the preparation and eliminating the skin sensitization caused by the original dog-skin plaster.
