STEARALKONIUM BENTONITE
Also known as: Stearalkonium Bentonite, Stearalkonium modified bentonite
Overview
Stearalkonium bentonite is a modified form of bentonite clay, treated with stearalkonium chloride to enhance its properties for use in cosmetic formulations. Bentonite clay is naturally derived from volcanic ash. It is primarily used as a thickener, stabilizer, and suspending agent in various cosmetic formulations, providing texture and stability to products like creams, lotions, and powders. Due to its low water solubility, stearalkonium bentonite is not expected to be significantly absorbed into the body. Research on stearalkonium bentonite is somewhat limited, with most studies focusing on safety assessments rather than specific health benefits. It is generally considered safe for topical use in cosmetics at specified concentrations. However, it's important to note that some studies indicate potential for eye irritation at higher concentrations.
Benefits
There is limited evidence on specific health benefits of stearalkonium bentonite in humans. Its primary function is to enhance the physical properties of cosmetic products. It acts as a thickener and stabilizer, improving the texture and shelf life of formulations. While it doesn't offer direct health benefits, its role in cosmetic formulations contributes to the overall user experience and product efficacy by maintaining consistency and preventing separation of ingredients. No significant population-specific benefits have been identified, and effect sizes have not been quantified in clinical studies.
How it works
Stearalkonium bentonite functions primarily as a physical thickener and stabilizer in cosmetic formulations. It does not significantly interact with biological systems due to its low bioavailability. Its mechanism of action involves creating a network within the formulation that increases viscosity and prevents the separation of ingredients. This is achieved through its unique structure and interaction with other components in the cosmetic product. It does not have known molecular targets or interact with specific biological pathways within the body.
Side effects
Stearalkonium bentonite is generally considered safe for use in cosmetics, but some potential side effects should be noted. The most common concern is potential eye irritation, particularly at higher concentrations. Studies have shown that it can cause slight to moderate irritation in rabbit eye tests. Skin sensitization is not a common side effect, as studies in guinea pigs have not indicated any sensitization potential. There are no reported drug interactions or contraindications associated with stearalkonium bentonite. However, it may contain trace impurities like quartz, which have carcinogenic potential if inhaled over prolonged periods. Therefore, manufacturers should ensure the purity of the ingredient to minimize this risk. No specific data is available regarding its safety in special populations such as pregnant women or children, so caution is advised.
Dosage
Stearalkonium bentonite is used as needed in cosmetic formulations, and there is no established minimum effective dose for health benefits. The optimal dosage range varies depending on the specific formulation requirements. In cosmetics, it is typically used in concentrations up to 6.5%. There is no established maximum safe dose for human health, as it is not intended for ingestion or internal use. Timing considerations are not applicable, as it is used as an ingredient in cosmetic products. Absorption factors are not relevant due to its low bioavailability. No required cofactors have been identified.
FAQs
Is stearalkonium bentonite safe for cosmetic use?
Yes, it is generally considered safe for topical use in cosmetics. However, it may cause eye irritation in high concentrations, so avoid direct contact with eyes.
Will stearalkonium bentonite be absorbed into my body?
No, it has low water solubility and is not expected to be significantly absorbed into the body when used topically in cosmetic products.
What does stearalkonium bentonite do in cosmetic products?
It acts as a thickener and stabilizer, improving the texture and shelf life of cosmetic formulations by preventing the separation of ingredients.
Are there any health benefits from using products containing stearalkonium bentonite?
No, it primarily serves a functional role in cosmetic formulations and does not offer direct health benefits.
Can stearalkonium bentonite cause skin irritation?
Skin sensitization is not common, but some individuals may experience mild irritation. Discontinue use if irritation occurs.
