What is SEPIGEL 305 Liquid?
SEPIGEL 305 is a liquid, ready-to-use polymer emulsifier, thickener, and stabilizer. It is widely used in cosmetic formulations to create smooth, non-greasy gel-creams and emulsions without the need for neutralization or heat.
How does SEPIGEL 305 perform in cold processing?
It is exceptionally well-suited for cold processing. Because it does not require heating or pre-dispersion, it helps save production energy, shortens manufacturing times, and preserves the stability of heat-sensitive active ingredients.
What is the recommended usage level of SEPIGEL 305?
The typical dosage ranges from 0.5% to 5% depending on the desired viscosity. For thickening, smaller percentages (0.5% - 2%) are sufficient, while formulating stable emulsions with high oil phases generally requires up to 3% - 5%.
What types of cosmetic products can incorporate SEPIGEL 305?
It is highly versatile and compatible with a wide array of skin care formulas, including facial creams, moisturizing body lotions, gel-creams, foundations, sunscreens, and after-sun care products.
Does SEPIGEL 305 handle high concentrations of electrolytes?
While SEPIGEL 305 provides excellent stability across a wide pH range (from 3 to 12), very high concentrations of electrolytes can reduce its viscosity. For formulas rich in minerals or salts, adjustments to the polymer concentration may be required.
