Carnosine is an unsaturated aldehyde that scavenges reactive oxygen species and peroxidizes fatty acids in cell membranes during oxidative stress. Low molecular weight water-soluble unmodified dipeptide-Ala-His has very little affinity for skin and does not penetrate beyond the first layer of cuticle. However, the lipophilic peptide palmitoyl-Ala-His diffused into the cuticle, epidermis, and dermis, and no systemic activity was observed.

Application Tips To obtain a smooth and neat finish, apply masking tape and remove before sealant cres. Paint surfaces completely before applying sealant. Before processing, observe the instructions in our product leaflets and safety data sheets. Product Description GP Acetic cure Silicone Sealant is a one-part, acid and moisture cure, medium modulus silicone sealant that provides durable, pliable, watertight joints and offers outstanding adhesion without priming to most non-porous substrates. Material preparation: For successful bonding, glass must be clean of all dust, dirt and oil. The cleaned glass should be wiped dry immediately with a clean, lint free cloth or blown dry with hot oil free air. DO NOT clean glass with soap and water solutions. Soap residue can cat as a release agent and result in adhesion failure. Clean glass should be handled with clean, lint free gloves or equivalent only. Oils from hands and fingers can act a release agents resulting in adhesion failure.

Tips: There are four main characteristics of the pharmaceutical cold chain: 1. Security In the evaluation of pharmaceutical cold chain transportation services, safety is at the forefront, which is determined by the particularity of logistics objects. 2. Sudden demand Due to the sudden outbreak of too many diseases, which are easily contagious and spread rapidly, the demand for refrigerated medicines is of a sudden nature, which requires high emergency service capabilities of logistics providers. 3. High cost Compared with the cost of ordinary transportation, the cost of cold chain transportation is generally about 80% higher 4. Professionalism The transportation and storage of medicines must be operated within a specific temperature range in accordance with national regulations, and in-transit GPS management must be implemented to achieve traceability of refrigerated medicines. Introduction to use: Cold compress: put it in freezer or freezer (-10℃ -- 20℃) for more than 30 minutes before use. Hot compress: wrap the cold and hot bag with a slightly wet towel, put it into the microwave oven and turn it to medium heat. Heat it for the first time within 60-100 seconds, and feel whether the temperature is appropriate after taking it out. If it is not hot enough, continue heating every 10-20 seconds until it is warm enough. If continuous use, subsequent heating time control in 50-60 seconds (medium heat). Hot water: Soak hot and cold bags in boiling water for about 4 minutes, or reheat for another 1 minute if the temperature is not enough.
