CAS Number: 9010-92-8
INCI: Styrene Acrylates Copolymer
Composition: SACP is a copolymer formed by the polymerization of styrene and acrylic monomers. The ratio of styrene to acrylic units can vary, resulting in copolymers with different properties and characteristics tailored for specific applications.
Purity Grade: No purity grade applicable
Appearance: SACP is commonly available as a white or off-white powder or in the form of an aqueous dispersion (latex). In its solid form, it appears as small granules or beads.
Solubility: SACP is insoluble in water but can be dispersed in water to form emulsions or latex. It may also be soluble or dispersible in organic solvents depending on its specific composition.
Preservation: SACP in its solid form typically does not require preservation. However, in aqueous dispersions or emulsions, appropriate preservation systems may be used to prevent microbial growth and maintain product stability.
Storage: Store in a closed container at a dry place at room temperature
Country of Origin: India
Raw Material Source: The raw materials for SACP, including styrene and acrylic monomers, are derived from petrochemical sources through various chemical processes.
Manufacture: SACP is manufactured through a polymerization process, where styrene and acrylic monomers are polymerized together under controlled conditions such as temperature, pressure, and initiator concentration. The polymerization process can be carried out via emulsion, solution, or suspension polymerization methods.
Animal Testing: Not animal tested
GMO: GMO-free (does not contain plant-derived components)
Vegan: Does not contain animal-derived components
Proposition: SACP complies with relevant regulations and guidelines.
Warning: Avoid contact with eyes and skin. Use appropriate protective equipment when handling.
General Description:
Styrene acrylic copolymer is a type of synthetic polymer made from the polymerization of styrene and acrylic monomers. It appears as a white or off-white powder or liquid emulsion, depending on its specific formulation. This copolymer is known for its film-forming, adhesive, and water-resistant properties, making it useful in a variety of applications.
Uses in the Cosmetic Industry:
- Film-Forming Agent: Styrene acrylic copolymer is widely used as a film-forming agent in cosmetics. It helps create a smooth, continuous film on the skin or hair, enhancing the product's durability and performance. This property is especially valuable in products like foundations, mascaras, and nail polishes.
- Binder: It acts as a binder in powder products, such as eyeshadows and pressed powders, helping to hold the ingredients together and improve the product's texture and application.
- Emulsion Stabilizer: Styrene acrylic copolymer helps stabilize emulsions, preventing the separation of oil and water phases in products like lotions and creams.
- Adhesive: It provides adhesive properties, making it useful in products like temporary tattoos, peel-off masks, and other applications where adhesion to the skin is required.
- Hair Styling Products: In hair care, it is used in styling gels, mousses, and sprays to provide hold, volume, and texture to hair. It helps maintain the hairstyle by forming a flexible film that resists humidity and environmental factors.
Hazards and Safety Concerns:
Styrene acrylic copolymer is generally considered safe for use in cosmetics, but there are some potential hazards and safety concerns:
- Skin Irritation: Some individuals may experience mild skin irritation when using products containing styrene acrylic copolymer. Symptoms can include redness, itching, and dryness. Those with sensitive skin should perform a patch test before using products containing this ingredient.
- Allergic Reactions: Although rare, allergic reactions to styrene acrylic copolymer can occur. Symptoms may include rash, hives, and swelling. Individuals with known allergies to synthetic polymers should be cautious.
- Eye Irritation: Direct contact with the eyes can cause irritation. Products containing styrene acrylic copolymer should be used with care to avoid eye contact.
- Inhalation Risks: Inhalation of dust or fumes from styrene acrylic copolymer (e.g., in powder form or during application of spray products) can cause respiratory irritation. Proper ventilation and protective equipment are recommended during manufacturing and application.
- Environmental Impact: Styrene acrylic copolymers are not readily biodegradable and can accumulate in the environment. Their widespread use and disposal can contribute to environmental pollution, particularly in aquatic ecosystems.
