Sodium Acrylate can be used as a flocculating agent in water treatment processes to remove impurities from water. 4. It is used in the manufacturing of coatings, adhesives, and polymers for a wide range of industrial applications. 5. Sodium Acrylate is also used in the production of paper and pulp as a retention aid and drainage improver. |
| Features And Benefits | 1. Sodium Acrylate is a water-soluble polymer that contributes to the texture and stability of cosmetic products. 2. It functions as a thickening agent, which helps to improve the viscosity and suspension properties of emulsions and lotions. 3. It has excellent absorbing properties, which makes it useful in formulations for oil control and mattifying effects. 4. It improves the spreadability of products on the skin, making them easier to apply. 5. Sodium Acrylate is used as an emulsion stabilizer, which helps to prevent the separation of oil and water in cosmetic formulations. |
What is sodium acrylates copolymer used for in cosmetics?
Sodium acrylates copolymer is used as a texture enhancer, binder, and film-forming agent in cosmetics.
What is the recommended concentration of sodium acrylates copolymer when used to enhance texture, stabilize, or suspend ingredients in an emulsion?
The recommended concentration of sodium acrylates copolymer ranges from 0.5%.
What is the maximum concentration of sodium acrylates copolymer that can be used when the goal is film-forming or binding agent?
The maximum concentration of sodium acrylates copolymer that can be used is up to 25%.
How does sodium polyacrylate function in body care products?
Sodium polyacrylate functions as a thickening agent, texture enhancer, film-forming agent, and emulsion stabilizer in body care products. It contributes to the smooth, glossy appearance of products and keeps the texture soft and supple while conditioning the skin.
What is the role of sodium polyacrylate in baby care products, specifically diapers?
In diapers, sodium polyacrylate absorbs water molecules found in urine, increasing the amount of liquid the diaper can hold while promoting a dry environment and reducing the risk of diaper rash.
How is sodium polyacrylate produced?
Sodium polyacrylate is produced by polymerizing acrylic acid and hydrolyzing the polyacrylic acid with an aqueous sodium hydroxide solution.
Can sodium acrylates copolymer irritate the skin?
Highly purified forms of sodium acrylates copolymer are considered safe and should not cause irritation when used in cosmetic products.
Does sodium polyacrylate have absorbent properties?
Yes, sodium polyacrylate is a super absorbent polymer that can absorb 100 to 1000 times its mass in water.
What are the different functions of sodium polyacrylate in a formulation?
Sodium polyacrylate acts as an absorbent, emulsion stabilizer, film former, hair fixative, skin conditioner, and viscosity controller in a formulation.
Has the safety of sodium polyacrylate been evaluated?
Yes, the Cosmetics Ingredient Review (CIR) panel has determined that sodium polyacrylate is safe for use in cosmetics.
