Polysilicone-13 is a chemical compound, siloxanes and silicones, Di-Me, Hydrogen-terminated, polymers with polyethylene-polypropylene glycol bis(2-methyl-2-propenyl)ether.
Silicones have high chemical stability but low biodegradability and high bioaccumulation potential.
The name describes the structure of the molecule:
- Polysilicone indicates that the compound belongs to the class of polysilicones, which are polymers containing silicone units. Polysilicones are known for their film-forming properties, moisture resistance, and ability to leave a smooth feeling on the skin.
- -13 is likely an identifier that distinguishes this specific molecule of polysilicone from others in the same class. It does not refer to a specific chemical property, but rather serves as a unique identifier for this type of polysilicone.
Description of Raw Materials Used in Production.
Polysilicone-13 is a silicone polymer, obtained from the polymerization of specific siloxanes and silanes. These base chemical compounds are primarily derived from silicon, an abundant element extracted from sand or quartz.
Step-by-step Summary of Industrial Production Process.
- Preparation of siloxane and silane monomers.
- Polymerization of the monomers under controlled conditions to form Polysilicone-13.
- Purification of the polymer to remove impurities and residual monomers.
- Quality control to ensure compliance with technical specifications.
Form and Color.
Polysilicone-13 typically appears as a clear, colorless liquid or as a viscous substance.

What it is used for and where
Cosmetics
Hair conditioning agent. A large number of ingredients with specific purposes can co-exist in a hair shampoo: cleansers, conditioners, thickeners, mattifying agents, sequestering agents, fragrances, preservatives, special additives. However, the indispensable ingredients are the cleansers and conditioners as they are necessary and sufficient for hair cleansing and manageability. The others act as commercial and non-essential auxiliaries such as: appearance, fragrance, colouring, etc. Hair conditioning agents have the task of increasing shine, manageability and volume, and reducing static electricity, especially after treatments such as colouring, ironing, waving, drying and brushing. They are, in practice, dispersing agents that may contain cationic surfactants, thickeners, emollients, polymers. The typology of hair conditioners includes: intensive conditioners, instant conditioners, thickening conditioners, drying conditioners.
Commercial Applications.
Used in various cosmetic and personal care products as an emollient and conditioning agent. It offers a smooth feeling and enhances the spreadability of products on skin or hair.
Safety.
It is an ingredient that has a high bioaccumulation and persistence, however in cosmetic use this ingredient is considered safe.
