Ava Perkins, a cosmetic chemist, discusses ingredient types, surfactants, preservatives, and pH in cosmetics. The podcast covers challenges faced by influencers, misconceptions about preservatives, role of emulsifiers in formulations, solubilizers for clarity, cindent bars formulation, and sunscreen formulation hurdles.
Formulating sunscreens can be challenging due to UV filter limitations and stability issues.
Understanding ingredient categories is crucial for creating effective skincare products.
Consumers should be vigilant for signs of product instability and be cautious of skincare misinformation online.
Deep dives
Challenges in Formulating Skincare
Formulating skincare products, especially sunscreens, can be challenging due to limitations on UV filters, complex issues with stability, and regulatory constraints. In the US, formulators face restrictions on UV filter choices and concentrations. Additionally, creating sunscreens with high UVA protection is difficult. Other products like cleansers may require careful consideration of surfactant concentrations and ingredients to ensure efficacy and user acceptance.
Ingredient Categories and Functions in Formulations
Formulators work with various ingredient categories to create effective skincare products. These include moisturizers, surfactants, stabilizing agents, thickeners, and active ingredients. Each category serves specific functions such as hydration, cleansing, preservation, texture enhancement, and targeted skincare benefits like anti-aging or acne treatment. Understanding the roles of these ingredients is crucial for developing well-formulated products.
Consumer Awareness and Product Stability
Consumers should be observant of signs of product instability, such as separation, discoloration, or changes in smell, especially in products like retinoids. Despite standardized stability testing, there is no easy way for consumers to assess formulation stability. Vigilance is key to ensuring product safety and efficacy over time.
Budget Constraints in Product Formulation
Formulators often need to adhere to budget constraints when creating skincare products. Budget considerations encompass ingredient costs, formulation complexity, and overall product efficacy. Balancing cost-effective formulations with quality, safety, and performance is a critical aspect of product development across different skincare categories.
Importance of Factual Information on Social Media
Consumers should approach skincare information on social media with caution and seek accurate, science-backed content. Misinformation and misconceptions abound in the industry, highlighting the need for critical thinking and scrutiny of product claims. Engaging with content creators for reliable information and asking questions can help navigate the wealth of skincare advice available online.
This week's episode is a 101 on cosmetics formulations; what are the ingredient types that make your products work and why? What’s up with surfactant and preservative systems? What’s the difference between skin and hair care, what’s an emulsion, and what do you need to know about pH? o help me cover the topic, this week featured Ava Perkins, PhD student at the University of Cincinnati in their cosmetic science program.
