In this module, we remove the confusion and guide you step by step through the entire process of identifying, calculating, and correctly listing allergens on your product labels. 

Essential oils and fragrance oils can add wonderful sensory benefits to cosmetic products, but they can also contain allergens that may trigger reactions in sensitive individuals. For this reason, cosmetic legislation in many countries requires certain fragrance allergens to be declared on product labels once they exceed specific thresholds. 

For many formulators, this part of compliance can feel overwhelming—especially when calculations, certificates, and regulatory terminology come into play.

This video class will take you step by step through identifying and calculating allergens, including guiding you through the math in an easy-to-follow way. You’ll learn exactly how to calculate the level of each allergen in your finished product, with clear explanations and worked-through examples.

You’ll learn:

• What allergens are and why they must be declared.
• How to find out which allergens are in your ingredients.
• How to read IFRA conformity certificates and allergen data sheets.
• How to calculate allergen levels in finished products.
• How to know if you need to include the allergen on your product label.
• Labeling thresholds for leave-on vs rinse-off products.
• How to correctly list allergens on cosmetic labels.

By the end of this module, you’ll know how to confidently decide whether an allergen needs to appear on your product label and how to list it correctly and compliantly. 

With practical examples and useful resources, you’ll be fully prepared to apply what you’ve learned to your own formulations—saving time, avoiding costly mistakes, and building confidence in your cosmetic labeling skills.

LABELING COSMETIC PRODUCTS WITH CONFIDENCE

Module 3: Calculating and Listing Allergens on Your Product Label is the third module in our Labeling Cosmetic Products with Confidence course. 

Take the whole course for a complete step-by-step guide to everything you need to include on your label, or take this module as a standalone class if you only need help with calculating and listing allergens.

Labeling your cosmetic products correctly is essential for selling them with confidence. Your product label might be small — but it carries big responsibility.

Beautiful packaging draws customers in, but your label also plays an essential role in keeping your products compliant, your customers informed, and your business protected.

When you sell cosmetic products, your label carries essential safety, ingredient, and compliance information that you’re legally required to provide. Trying to figure out what you need to include can feel overwhelming and confusing 

Our five-module Labeling Cosmetic Products with Confidence course takes the overwhelm out of cosmetic labeling and shows you, step by step, exactly what needs to go on your products — and how to do it correctly and confidently.

In the course, you’ll learn:

MODULE 1: WHAT NEEDS TO BE INCLUDED ON A PRODUCT LABEL?
MODULE 2: WRITING YOUR INGREDIENT INCI LIST
MODULE 3: CALCULATING AND LISTING ALLERGENS ON YOUR PRODUCT LABEL
MODULE 4: SYMBOLS, EXPIRY DATES AND BATCH NUMBERS FOR PRODUCT LABELS
MODULE 5: VISUAL BRANDING AND LABEL DESIGN 

By the end of the course, you won’t just have labels that look lovely — you’ll have labels that meet requirements, build customer trust, and support your business as it grows.
