- Content: Usually, there are cosmetic - grade products, etc., with a content of ≥98%. The contents of C18 and C16 vary among different products. For example, in some products, the C18 content is 73.92% and the C16 content is 26.78%.
- Packaging Specifications: Commonly, it is 20 - 25 kg/bag or barrel.
- Production Method: It is obtained by esterification, hydrogenation and fractionation of natural oils and fats, or can be prepared by continuous hydrogenation of coconut oil in a copper - chromium catalyst, followed by distillation, cutting and other processes.
- Applications
- Cosmetic Field: It is one of the base materials for cosmetic creams and lotions. It can be used as a matrix, especially suitable for creams and lotions. It can increase the consistency and stability of products, giving them a better texture. It can also be used as an emulsifier, thickener, lubricant, etc. When used in combination with surfactants, it can form emulsions with complex micro - structures.
- Pharmaceutical Field: In topical preparations, it can increase the viscosity of w/o and o/w emulsions, play a role in stabilizing emulsions and has a co - emulsifying effect, reducing the amount of surfactants required to form stable emulsions. It is also used to prepare non - aqueous creams and lip balms, and can reduce the release of water - soluble drugs. It is directly used in w/o emulsifier pastes, ointment bases, etc.
- Other Fields1: It can be used as a textile auxiliary in the textile industry, a leather auxiliary in the leather industry, a lubricant in the plastic and resin industries. In addition, it can also be used in the synthetic detergent industry, and is also an intermediate for preparing cationic surfactant quaternary ammonium salts and amphoteric surfactants.
- Storage and Transportation
- Storage: It should be stored in a cool and dry place, avoiding sun exposure and rain. The shelf life is generally two years.
- Transportation: It is not a hazardous chemical, and should be transported according to the transportation requirements of general chemicals.
