1. Octocrylene is a UV-B filter that is approved in the USA, Europe, and Japan for use in sun care preparations. 2. Octocrylene is miscible with many cosmetic oils, it can easily be incorporated into the oily phase of an emulsion 3. Octocrylene is hydrophobic and oil-soluble, it is preferred for water-resistant and water-repellant formulations octocrylene is also compatible with all common plasticizers. Function & Application Octocrylene is a UVB sunscreen with strong water-resistant properties and a rather broad-band absorption range. It exhibits good photostability and is being evaluated by many companies as an effective SPF booster and waterproofing enhancer. This is an expensive ingredient with an approved usage level of 7 to 10 percent in both the United States and the European Union. Although gaining in popularity among formulators, its cost and usage level can limit use. In addition, some studies are indicating it may cause allergic reactions in the skin with a history of photoallergy. Use: Octocrylene is chemically related to cinnamates. It can be used to boost SPF and improve water resistance in a given formulation. Octocrylene is photostable and can improve the photostability of other sunscreens. It is expensive and can present difficulties in the formulation.

The UV laser marking machine is developed by using a 355nm UV laser. This machine uses a third-order intracavity frequency doubling technology. Compared with infrared lasers, the 355nm UV laser has a very small spot, and the marking effect is directly interrupted by a short-wavelength laser. The molecular chain greatly reduces the mechanical deformation of the material. Thermal deformation (cold light), because it is mainly used for ultra-fine marking and engraving. It is especially suitable for applications such as marking, micro-hole drilling of food and pharmaceutical packaging materials, high-speed dicing of glass materials, and complex pattern cutting of silicon wafers.
Psyllium husk also simply called psyllium are parts of the seeds of the plant Plantago ovata of the genus Plantago which native to India but can be found elsewhere. Psyllium husks are hygroscopic, capable of absorbing fluids primarily used as bulk forming laxative and a good source of dietary fiber and used commercially to produce mucilage. Product Name - Psyllium Husk Specification - 40 mesh Appearance - White Husk Grade - Food/Pharmaceutical grade Test methold - TLC Extraction Type - Solvent Extraction
