원료 설명

효능 Rheology additives, High purity, High whiteness, Thixotropic flow behavior, Excellent anti-settling properties, Improvement of storage stability, Widely applicable in aqueous systems

Rheology additive based on synthetic phyllosilicate for aqueous systems to provide thixotropic stabilization in personal care applications. [Product family] LAPONITE is BYK´s brand for synthetic phyllosilicate-based rheology additives for aqueous systems. LAPONITE additives increase the viscosity mainly in the low shear range and generate a thixotropic flow behavior. LAPONITE products provide excellent anti-settling properties and storage stability. They also improve the processability and application properties of various systems. LAPONITE additives are very pure synthetic phyllosilicates with no influence on the color of the system to which they are added. They can be used in the most varied of aqueous systems such as coatings, construction chemicals, household, industrial, and institutional applications, agricultural applications, care products, adhesives and sealants, and as film formers in energy storage applications. LAPONITE-XL 21 is suitable for use in formulations with a pH value of 5.5 and lower. In water or aqueous solutions of alcohols, it swells to clear and colorless colloidal dispersions, leading to the formation of a gel structure. At additive concentrations of more than 2 % in water, strongly thixotropic gels are formed. The unique thixotropic properties provided by LAPONITE-XL 21 improve the skin feel of personal care products and create a light, non-sticky texture. In addition, the additive enhances the stability of emulsions and prevents the settling of particles, pigments, and solid actives. It is compatible with solutions of up to 40 % ethanol. When used in combination with co-thickeners, it can be added to formulations containing > 60 % ethanol. 적용: Creams and lotions (especially recommended), Sunscreen products (especially recommended), Depilatory creams (especially recommended), Toothpastes (especially recommended), Shower gels and shampoos (especially recommended), Liquid makeup (especially recommended), Eye makeup (especially recommended) [Incorporation] LAPONITE-XL 21 should be added steadily to deionized water at a temperature of 15 to 25 °C under high shear within 10 to 30 seconds. It should be stirred fast enough that a turbulent vortex current is formed, so that the powder is well dispersed and clumps are avoided. After complete addition, stirring is continued for 20 minutes. At complete dispersion, a clear, colorless, and low-viscosity pre-mix is obtained. Once this pre-mix is combined with other components of the formulation, viscosity develops instantaneously. This can be affected by temperature, electrolytes, or pH value. [Note] LAPONITE-XL 21 is not compatible with cationic compounds. Therefore, for pH adjustment, citric acid, lactic acid, or sodium dihydrogen phosphate are recommended to lower the pH value and sodium hydroxide to increase the pH value. As the additive is a weak base and can thus lead to an increase in pH, it may be necessary to adjust the initial pH to a value below the target pH value.
