Sodium Acryloyldimethyltaurate丨CAS 5165-97-9

Sodium acryloyldimethyltaurate丨CAS 5165-97-9 is a synthetic polymerizable monomer primarily used in the production of copolymers. It is most commonly found in personal care, cosmetic, and pharmaceutical formulations as a key component in stabilizing emulsions, suspensions, and gels.

1. Cosmetics and Personal Care Products
a. Thickening Agent
● One of the primary applications of Sodium acryloyldimethyltaurate丨CAS 5165-97-9 is as a rheology modifier in water-based formulations.
● It is used in gels, creams, lotions, and serums to provide a smooth texture, viscosity control, and spreadability.
b. Emulsion Stabilizer
● Helps stabilize oil-in-water (O/W) emulsions without the need for high levels of emulsifiers.
● Especially effective in formulations containing silicones, esters, or natural oils, where conventional emulsifiers might fail.
c. Suspending Agent
● Used to suspend active ingredients, exfoliants, pigments, and other insoluble particles in cosmetic and skincare formulations.
● Ensures even distribution of particles and improves product consistency.
d. Mildness and Compatibility
● Well-suited for sensitive skin and eye-area products due to its non-irritating nature.
● Compatible with a broad pH range (4.0–8.0), making it ideal for facial care and medicated topical formulas.
Common product types:
● Moisturizing creams and lotions
● Sunscreens and after-sun gels
● Anti-aging serums
● Makeup primers and foundations
● Cleansers and micellar waters

2. Pharmaceutical and Dermatological Products
● Functions as a carrier and delivery matrix for active pharmaceutical ingredients (APIs) in topical formulations.
● Used in dermatological gels, wound care products, and transdermal systems where stable viscosity and drug dispersion are important.
● Suitable for semi-solid drug formulations where skin compatibility and formulation stability are crucial.

3. Industrial and Household Applications
a. Home Care Products
● Used in fabric softeners, laundry liquids, and cleaning gels to stabilize the formulation and improve texture.
b. Industrial Coatings and Inks
● In some applications, sodium acryloyldimethyltaurate is used in water-based coatings, inks, or adhesives as a stabilizer or viscosity modifier.
c. Paints and Dispersions
● May be used in pigment suspensions or latex formulations where rheology control is required.

1. Excellent Rheological Control
● Provides pseudoplastic (shear-thinning) behavior-easy to apply and spread, but thickens at rest, improving stability and user experience.
● Ensures a silky, non-tacky feel without greasiness.
2. High Stability and Compatibility
● Stable in formulations containing electrolytes, alcohols, and ionic actives, unlike some natural gums or traditional thickeners.
● Remains effective in a wide pH range (4–8) and across various temperatures.
3. Enhances Product Aesthetics
● Offers a clear, glossy finish in gels and creams, contributing to the visual appeal of high-end cosmetic products.
● Maintains smooth texture and non-soapy feel, enhancing consumer perception.
4. Versatile Emulsification
● Helps create stable emulsions with minimal use of traditional surfactants or emulsifiers, which can be irritating or comedogenic.
● Suitable for cold-process formulations, saving energy and reducing production complexity.
5. Skin-Friendly Profile
● Non-sensitizing, non-toxic, and dermatologically safe, even for sensitive and allergy-prone skin types.
● Free from parabens, PEGs, and other controversial additives, supporting "clean beauty" standards.

Conclusion
Sodium acryloyldimethyltaurate丨CAS 5165-97-9 is a multifunctional cosmetic polymer that brings significant value across personal care, pharmaceutical, and industrial applications. Its exceptional rheology-modifying and stabilizing properties make it a cornerstone ingredient in modern cosmetic science, particularly for lightweight, non-greasy, and electrolyte-stable formulations.
