Applications
In the field of thixotropy and thickening performance, after swelling in water, it forms highly transparent, high-viscosity nanoscale colloids. When subjected to shear force such as shaking, extrusion or spreading, its viscosity drops rapidly for outstanding fluidity. Once at rest, viscosity recovers quickly to prevent phase separation of the system.
In the field of suspending and emulsifying stabilizing capacity, it delivers effective suspension of insoluble particles, pigments and fine pearlescent agents within formulations and inhibits sedimentation or oil-water separation throughout storage.
In the field of refreshing, mild sensory profile, compared with certain conventional organic thickeners, it boasts great biocompatibility and gentleness. Therefore, it delivers a smooth, non-tacky feel and is non-irritating to the skin and eyes.

FAQ
Q1: Compared with conventional polymeric thickener, such as Carbomer, Xanthan Gum, what is the key competitive advantage of Sodium Magnesium Silicate?
A: Firstly, it has excellent thixotropy. In other words, it presents a high viscosity gel state when at rest to prevent flow, and its viscosity rapidly and easily decreases when squeezed or applied. Secondly, it delivers excellent electrolyte tolerance. Because it is insensitive to salt, such as irons from active ingredients and preservatives, it does not lose water or “collapse” like Carbomer when encountering salts. Thirdly, it performs more lighter, fresher sensory.
Finally, its transparency is very high. High-quality synthetic lithium magnesium silicate can achieve over 99% transmittance after dispersion, not affecting the crystalline appearance.
Q2: In the formulation production, how should lithium magnesium sodium silicate be correctly used and dispersed?
A: The correct dispersion process is key to leveraging its effectiveness. For example, in the process of pre-dispersion and hydration, this raw material should be slowly added into deionized water with the condition of high-speed stirring. Continue high-shear mixing for a set duration, making it adsorb abundant water, become swell, and peel into nanosheet layers. (Note: Hot or warm water helps accelerate hydration). Given that usage level, the recommended usage is from 0.5% to 3.0%. Most importantly, the usage level should be based on the required viscosity and suspension. For pH value, it shows optimal gel performance and stability in a neutral to mildly alkaline environment (pH 7-11).
Q3: What precautions should be taken when using this raw material?
A: First, incomplete dispersion leads to “graininess”. In detail, if the stirring shear force is insufficient, the nanosheet layers will not fully separate, leaving a gritty or speckled sensation in the gel or final product.Secondly, in the field of pH compatibility, you should be careful when used in strongly acidic formulations. Besides, a low pH value may affect its charge balance and gel network structure.In a compatibility testing, although it delivers excellent electrolyte tolerance, it should be conducted preliminary compatibility and thermal stability testing in high concentrations of cationic surfactants or specific strong polar systems to prevent flocculation.
Q4: How does this raw material perform in terms of environmental friendliness and safety?
A: lithium magnesium sodium silicatefalls within the category of inorganic mineral synthetic derivatives (silicate), delivering high biocompatibility. In detail, due to its non-toxic and non-irritating, it is gentle on skin and eyes and not cause allergies. Besides, it is an environmentally friendly raw material with low pollution impact and does not accumulate in the environment. As a result, it complies with current trends in green cosmetics and clean beauty regarding raw material safety and sustainability.
Q5: How can one quickly assess or test the quality of a batch of lithium magnesium sodium silicate raw materials?
A: The following are the core indicators:
Firstly, in the aspect of transmittance or transparency, when this ingredient is formulated into gels at a standard ratio, such as 2% aqueous solution, use a spectrophotometer or visual inspection to observe transmittance. Gels that contains high-quality raw materials should be crystal clear, without black spots, impurities, or undissolved particles.
Secondly, in the aspect of whiteness, the whiteness of the powder itself usually needs to be above 90. The higher the whiteness, the greater the mineral purity and the more advanced the refining processes.
Thirdly, in the aspect of swelling rate and viscosity, under the same stirring conditions, observe the rate at which it absorbs water and forms a stable thixotropic gel, as well as the final viscosity value.
Q6: Can it be compounded with other thickeners, such as cellulose, xanthan gum and carbomer? What advantages does that provide?
A: It is very suitable for compounding and often produces a "1+12" synergistic effect.
When natural polysaccharide polymers such as xanthan gum and cellulose are incorporated in formulations, they readily create a stringy or sticky sensation. The addition of lithium magnesium sodium silicate effectively removes stringiness, delivering pastes with a fresher feel and short flow, while substantially boosting suspension performance.
When carbomer and lithium magnesium sodium silicate are compounded in formulations, dosage of carbomer can be greatly lowered, while its performance limitations under electrolyte-containing conditions are overcome. Therefore, the overall skin feel will be optimized.
Regulatory compliance
China: It is a conventional raw material in the list of cosmetics (IECIC) that is already on the market, and does not require independent registration as a new raw material; it can be directly used in formulations. Most importantly, it must strictly comply with the China’s Safety and Technical Standards for Cosmetics (2015 Edition) for the limits of heavy metals, such as lead, arsenic, cadmium, mercury.
EU: Silicate raw materials have a mature safety assessment history in the EU, such as CIR or SCCS systems. However, if the product involves “Nanomaterials”, full notification of nano status must be submitted via the EU CPNP portal, and this ingredient shall be labelled accordingly within the ingredient list. It delivers micro-nano sheet structures, so it must comply with the above requirement.
United States: It is a conventional cosmetic raw material in the United States. What’s more, CIR-Cosmetic Ingredient Review is supported by completed safety assessments, which consider it safe at conventional usage concentrations.
Canada: It is a conventional cosmetic raw material in the Canada, and not ahazardous ingredients that are prohibited or subject to strict restrictions.
Australia: As a regular industrial or commercially introduced chemical, it has a legal status in Australia.
Japan: As a regular chemical listed in Japan's "Chemical Substance Control Law" (CSCL), it is allowed for import and industrial use within a compliant legal framework, and does not need to apply for lengthy, high-cost pre-market safety assessments as a "new chemical substance."
