Understanding the Importance of Rheology Modifiers in Cosmetics
What is a Rheology Modifier?
A rheology modifier is a material used to alter the flow properties of a formulation, either by thickening or thinning it. Essentially, it influences the viscosity of a product, which is the measure of its resistance to flow. The higher the viscosity, the more resistant the product is to flow. This characteristic is crucial in cosmetics as it directly affects the application and feel of products. For instance, a cream typically needs a higher viscosity to remain stable on the skin, while a toner, which is more fluid, requires a lower viscosity.
Why is This Relevant in Cosmetic Products?
Different cosmetic products require varying viscosities to meet consumer expectations and deliver the desired experience. For example, the distinction between a cream and a lotion primarily lies in their viscosity. While both can contain similar ingredients, creams are perceived as more moisturizing due to their thicker consistency, even though this is not necessarily the case. This perception drives consumer preference and choice.
Additionally, the rheology of a product impacts its usability and effectiveness. Consider shower gels: if they were as fluid as water, they would be wasteful and challenging to use, despite potentially providing the same cleansing benefits. The thicker, gel-like consistency enhances the user experience by making the product easier to apply and control, reducing waste and improving satisfaction.

Additional key properties include reduced greasiness/sliminess/stickiness, excellent oil absorption, and a blurring effect leaving the skin looking and feeling hydrated, smooth and glowing. The H-33 provides an excellent SPF boost especially in W/O emulsions. The†H-33†is COSMOS/Ecocert certified.
SOLESPHERE™ H-53
SOLESPHERE™ H-53 is a specialty mineral microspherical silica. The H-53 has a 5 µm particle size and improves aesthetics, feel and enhances slip. Additional key properties include reduced greasiness/stickiness, good oil absorption, and provides excellent SPF boosting in O/W emulsions as well as W/O emulsions. The H-53 is COSMOS/Ecocert certified.
Rice Starch
Natura-Tec Rice Starch is a finely powdered, plant-based ingredient known for its exceptional absorption properties. Its small particle size significantly increases surface area, enhancing its absorption capabilities. When added below 50°C in cosmetic formulations, it imparts an exquisite soft-touch sensation, while heating it above 70°C in the water phase transforms it into a gelling agent. This versatile ingredient is perfect for decorative cosmetics, skincare, and haircare products, offering a long-lasting matte appearance in skincare, soothing properties for irritated skin, and oil-absorbing benefits for beautiful hair. Additionally, it allows for the creation of “Talc free” products and acts as a co-gelling agent in emulsion systems when used at higher temperatures.
Vegetable Beeswax
Natura-Tec Vegetable Beeswax stands out as an eco-friendly and sustainable 100% plant-based wax, aligning perfectly with vegan principles and fostering environmental awareness. This remarkable ingredient serves as an exceptional consistency enhancer, boasting pliable properties at body temperature that effectively nurture, hydrate, and soften the skin. Its outstanding compatibility makes it effortless to incorporate into various cosmetic formulations. Comparative analysis against its animal-derived counterpart demonstrates equivalent performance up to 10% in emulsion systems, maintaining viscosity, pH, sensorial attributes, and stability. When employed in combination with other waxes in lipstick formulations, it exhibits identical characteristics in terms of cracking resistance and sensory qualities. Notably, when utilized as the sole component in a lip balm at a 25% concentration, it displays exceptional oil-binding capacity and structure enhancement. Natura-Tec Vegetable Beeswax is the preferred choice for replacing animal-derived beeswax in cosmetic applications spanning lipsticks, eyeliners, mascaras, cosmetic pencils, lip balms, skincare emulsions (both water-in-oil and oil-in-water), natural depilatory waxes, hair care products such as conditioners, styling waxes, and hair masks, as well as in candles and soaps.
