Viscosity
Viscosity is a key concept in cosmetics that describes how thick or runny a product is. Think of it as the measure of a product's flow - like how honey flows more slowly than water. In cosmetics development, controlling viscosity is crucial because it affects how products feel, how they spread, and how stable they stay on the shelf. When you see this term in resumes, it usually means the person has experience in formulating or testing products to achieve the right consistency, whether it's for lotions, creams, shampoos, or other beauty products.

Example Interview Questions
Senior Level Questions
Q: How do you approach viscosity problems in a new formulation?
Expected Answer: A senior formulator should explain their systematic approach to troubleshooting, including testing different thickeners, considering temperature effects, and maintaining product stability while achieving desired consistency.
Q: How do you balance viscosity requirements with cost considerations in product development?
Expected Answer: Should discuss strategies for optimizing formulations to meet both technical requirements and budget constraints, including ingredient selection and process efficiency.
Mid Level Questions
Q: What factors affect product viscosity in cosmetic formulations?
Expected Answer: Should mention temperature, pH, ingredient interactions, and preservation methods as key factors affecting product thickness and flow properties.
Q: How do you measure viscosity in different types of cosmetic products?
Expected Answer: Should describe various measurement methods and tools used for different product types, from liquid to cream formulations.
Junior Level Questions
Q: What is viscosity and why is it important in cosmetic products?
Expected Answer: Should explain that viscosity is about product thickness and flow, and how it affects product performance, user experience, and stability.
Q: Name some common ingredients used to adjust viscosity in cosmetics.
Expected Answer: Should be able to list basic thickeners and explain their general use in different types of products.
