Q1: What is the primary function of Emulan AT9 Emulsion in cosmetic and personal care formulations?
A: Emulan AT9 Emulsion is a non-ionic oil-in-water emulsifier designed to stabilize a broad range of oily phases—including silicones, esters, and natural oils—into aqueous systems. It supports the formation of elegant, low-viscosity emulsions with good skin feel and long-term physical stability.
Q2: Is Emulan AT9 suitable for use in rinse-off or leave-on products?
A: Yes, Emulan AT9 is versatile across both rinse-off (e.g., shampoos, body washes) and leave-on applications (e.g., lotions, serums, sun care). Its mildness profile and compatibility with common surfactants and active ingredients make it appropriate for sensitive-skin formulations.
Q3: How should Emulan AT9 Emulsion be incorporated into a formulation?
A: It is typically added to the aqueous phase at room temperature or during the cool-down stage. For optimal emulsification, gentle homogenization or high-shear mixing is recommended after combining with the oil phase. Pre-mixing with co-emulsifiers or stabilizers may enhance performance in challenging systems.
Q4: Does Emulan AT9 Emulsion contain ethoxylated surfactants or animal-derived components?
A: Emulan AT9 Emulsion is based on ethoxylated fatty alcohols and does not contain animal-derived raw materials. It is suitable for vegan formulations and complies with common industry expectations for responsible sourcing and transparency.
Q5: Can Emulan AT9 be used in preservative-free or reduced-preserve systems?
A: While Emulan AT9 itself does not provide antimicrobial activity, its low water content and stable emulsion structure can support preservation efficacy. However, preservative selection and challenge testing remain essential—formulations must be validated according to regional regulatory requirements and intended shelf life.
