Product Description
Enhance Your Formulations with Sodium Polyaspartate: The Ultimate Moisturizer and Softening Agent for Skin, Hair, and Cleaning Products
Sodium Polyaspartate is a versatile, eco-friendly ingredient widely used in both personal care formulations and cleaning products. It serves as an excellent moisturizing agent, helping your products retain moisture and improve the hydration of skin and hair. Additionally, it enhances the cleaning effectiveness of household and industrial products, making it an ideal choice for a wide range of applications. As a biodegradable ingredient, Sodium Polyaspartate ensures your formulations are environmentally friendly while still providing superior performance.
- High molecular weight polyaspartic acid has strong moisturizing properties. Adding it to moisturizing skin care products can make the skin softer and smoother;
- When used in shampoo, conditioner, and hair spray, it not only cleans, moisturizes, softens, and shapes the hair, but is also very easy to wash off from the hair;
- As an anionic polymer, polyaspartic acid has a large number of carboxyl groups on the main chain of the molecule. When used in the pH environment of the oral cavity, it reduces the adhesion of bacteria to hydroxyapatite, thereby inhibiting the plaque formation on the tooth surface and inhibiting the formation of calcification on the tooth surface;

Key Benefits of Sodium Polyaspartate
Discover the Power of Sodium Polyaspartate in Your Personal Care and Cleaning Products
1. Superior Moisturization for Skin & Hair Care
In skin care and hair care products, Sodium Polyaspartate works as an effective moisturizing agent that helps to retain hydration. It is especially beneficial in shampoos, conditioners, body lotions, and other personal care products. The ability of Sodium Polyaspartate to improve moisture retention leaves skin feeling softer, smoother, and more hydrated, while keeping hair nourished and manageable.
Its exceptional moisturizing properties make it an ideal ingredient for products designed to address dry skin or hair, particularly in dry or cold climates. Whether used in moisturizers, shampoos, or conditioners, it adds a layer of hydration that promotes long-lasting softness and comfort.
2. Softening Properties for Sensitive Skin
As a softening agent, Sodium Polyaspartate enhances the smoothness and texture of the skin, making it perfect for sensitive skin care products. Its gentle nature, combined with its biocompatibility, ensures it will not irritate the skin, making it suitable for those with delicate or allergy-prone skin. Whether added to body lotions or hand creams, Sodium Polyaspartate helps deliver a soft, velvety feel that is ideal for sensitive skin formulations.
Products that contain Sodium Polyaspartate provide a comforting experience for users, offering not only effective hydration but also a gentle touch.
3. Anti-Static and Frizz Control for Hair Care
One of the standout benefits of Sodium Polyaspartate in hair care products is its ability to reduce static and prevent frizz. In shampoos, conditioners, and styling products, Sodium Polyaspartate helps form a protective barrier around the hair, reducing friction and preventing hair from becoming tangled or frizzy. This is particularly beneficial for individuals with dry or coarse hair, as it keeps strands smooth and shiny, even in challenging conditions.
Its ability to control frizz and add smoothness makes it a popular choice for premium hair care products aimed at improving hair texture and appearance.
4. Hard Water Resistance for Cleaner Skin and Hair
In addition to its moisturizing and softening properties, Sodium Polyaspartate also acts as a hard water softener. It helps reduce the negative effects of hard water, which contains high levels of calcium and magnesium ions. These minerals can lead to scale buildup on skin and hair, leaving a residue that can be harsh and drying.
By binding to these minerals, Sodium Polyaspartate prevents mineral deposits from forming, ensuring that products perform optimally in regions with hard water. This improves the foaming action of shampoos, body washes, and other cleansing products, providing a smoother and more effective clean.
5. Enhances Cleaning Power in Household Products
Sodium Polyaspartate is not only beneficial in personal care but also in various cleaning products. When added to surface cleaners, dishwashing liquids, or laundry detergents, it acts as a powerful cleaning aid. It helps break down grease and dirt, making the cleaning process more efficient and thorough.
Its ability to enhance foaming action and improve the overall cleaning efficacy makes it a popular ingredient in both domestic and industrial cleaning formulations. Whether you are formulating multipurpose cleaners or specialized household detergents, Sodium Polyaspartate can help you achieve superior results.
Main Applications
The Applications of Polyaspartic Acid(PASP)
Sodium Polyaspartate is perfect for a wide range of personal care and cleaning products, including:
- Personal Care: Shampoos, conditioners, moisturizers, body lotions, hand creams, facial cleansers, and more.
- Cleaning Products: Surface cleaners, dishwashing liquids, laundry detergents, multipurpose cleaners, and industrial cleaning solutions.
As a leading supplier of Sodium Polyaspartate, we offer high-quality products in bulk for use in a variety of formulations. Whether you are a cosmetics brand, a cleaning product manufacturer, or a company in need of eco-friendly ingredients, our Sodium Polyaspartate can meet your specific needs.
In Cosmetics

Using a skin moisture tester and a skin moisture loss tester, the moisture content and transepidermal water loss of moisturizing cosmetics added with low and high molecular weight and different mass fractions of sodium polyaspartate (PASP) were examined after they were applied to human skin. The results show that high molecular weight PASP has a better moisturizing effect on the skin and a significant water-locking effect. When the mass fraction of high molecular weight PASP is 0.8%, the growth rate of skin moisture content reaches more than 0.5%, and the moisturizing effect on the skin is comparable to that of transparency. The acid content is quite high. An in vitro transdermal experiment was conducted on fresh pig skin using a skin elasticity tester to test the changes in pig skin elasticity before and after using PASP, which showed that PASP has the effect of improving skin elasticity. PASP has good development prospects as a moisturizer in cosmetics instead of the currently widely used hyaluronic acid.
In Shampoo,Conditioner and Hair Spray
Sodium polyaspartate has the functions of nutrition, repair and moisturizing, and can make hair combable and soft. The repair effect of sodium polyaspartate (PASP) with different mass fractions and different molecular weights on damaged hair was studied by scanning electron microscopy and contact angle tester. The results showed that the gloss of hair was improved after repair by high molecular weight sodium polyaspartate with a mass fraction of 1%, the contact angle increased by 9°, and the hair surface became hydrophobic; the effect of high molecular weight sodium polyaspartate with different mass fractions on the combability and softness of hair stem was studied by INSTRON tensile testing machine and ASHLAND SLT components. The results showed that the hair was easy to comb and soft after being treated with high molecular weight sodium polyaspartate with a mass fraction of 0.4%.


In Toothpaste
As an anionic polymer, polyaspartic acid has a large number of carboxyl groups on the main chain of the molecule. When used in the pH environment of the oral cavity, it reduces the adhesion of bacteria to hydroxyapatite, thereby inhibiting the plaque formation on the tooth surface and inhibiting the formation of calcification on the tooth surface;
