Polysilicone-28 is a silicone chemical compound, a complex copolymer made by reacting Aminopropyl Dimethicone with the thiolactone of acetylhomocysteine.
The name defines the structure of the molecule
- Poly indicates that the compound is a polymer, meaning it consists of many repeating units of a particular molecule.
- Silicone refers to the specific type of polymer, containing a backbone made up of silicon and oxygen atoms. Silicones are known for their lubricating and moisture-sealing properties.
- 28. The number often relates to the specific structure or molecular weight of the polymer. In the case of Polysilicone-28, it may indicate the number of repeating units, the length of the polymer chain, or other specific characteristics related to the chemical structure.
Description of raw materials used in production
Silicon: The chemical element used as a starting point in the production of silicone compounds.
Organic Compounds: Various organic compounds, such as methyl and phenyl, may be used to create different properties in the final polymer.
Catalysts: Often used to facilitate the polymerization reaction.
Step-by-step industrial chemical synthesis process
- Monomer Preparation: The basic silicone monomer is prepared through a series of chemical reactions that include the use of silicon and organic compounds.
- Polymerization: The monomers are then polymerized using an appropriate catalyst. The length of the polymer can be controlled through the reaction conditions.
- Modification: Any functional groups can be added to give the polymer desired properties.
- Purification: The polymer is purified to remove any impurities or by-products.
- Formulation: Polysilicone-28 may then be formulated with other ingredients to create final products like lubricants, conditioning agents, or cosmetics.
What it is used for and where
Cosmetics
Hair fixative. This ingredient has the ability to create, with its protective film, stiffness and hold in the hair, and also has the ability to form, with its hydrophilic and elastic properties, bonds between the hair fibres, to keep the hair in a particular shape for a certain time.
Skin conditioning agent. An ingredient that is the mainstay of topical skin treatment by restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants.
Safety
It is an ingredient that has high chemical stability, but low biodegradability, high bioaccumulation and persistence, however in cosmetic use this ingredient is considered safe.
Commercial applications
Hair Products: Used in conditioners, hair sprays, and styling products to enhance manageability, reduce frizz, and add shine.
Skin Products: Found in creams, lotions, and primers to improve texture, create a smoothing effect, and aid in oil control.
Properties
Emollient: Provides a soft and silky feel on the skin and hair.
Film-forming: Creates a thin film on the skin or hair that helps to retain moisture and protects.
Antistatic Agent: Helps to reduce static electricity, making hair easier to comb and reducing frizz.
Oil Control: May help control skin's oiliness, making it useful in products for oily or combination skin.
