Is Kosas Vegan?

By Olivia

In this article, we will explore whether Kosas products are vegan-friendly or not. We will delve into the ingredients used in their formulations, their manufacturing processes, and any certifications they may hold to determine if Kosas is a vegan brand.

Ingredients Used in Kosas Products

Kosas is known for its clean beauty products, prioritizing the use of high-quality, natural ingredients. Their formulations are free from potentially harmful chemicals like parabens, sulfates, and phthalates. While their focus is on creating products that are safe and gentle for the skin, not all of their products are vegan.

Some of the key ingredients used in Kosas products include:

  • Jojoba oil
  • Shea butter
  • Avocado oil
  • Rosehip seed oil

These ingredients are plant-based and don’t involve any animal-derived substances. However, there might be other ingredients used in their products that are not suitable for vegans. It is essential to examine each product individually for a comprehensive understanding.

Animal-Derived Ingredients to Consider

Although Kosas emphasizes using plant-based ingredients, some of their products may contain animal-derived substances. It’s crucial to be aware of these ingredients to make an informed decision when purchasing Kosas products. Here are a few examples:

  1. Lanolin: Derived from sheep’s wool, lanolin is commonly used in lip products for its moisturizing properties. Check the ingredient list to see if any Kosas lip products contain lanolin.
  2. Carmine: Often used as a red pigment, carmine is derived from crushed insects. Look out for this ingredient in Kosas makeup products like blushes or lipsticks.
  3. Honey: Some skincare products, particularly those designed for hydration and nourishment, may contain honey. If you follow a strict vegan lifestyle, be cautious of these products.

While the ingredients mentioned above are not exhaustive, they give you an idea of certain animal-derived substances that may be present in Kosas products. To ensure a product is vegan, always refer to the ingredient list provided by the brand.

Manufacturing and Certifications

Kosas is committed to ethical and sustainable practices, but they do not explicitly label their products as vegan. However, they are certified by the Leaping Bunny Program, which indicates that their products are not tested on animals. This certification ensures that Kosas follows strict cruelty-free standards. While cruelty-free doesn’t necessarily mean vegan, it does indicate the brand’s commitment to ethical practices.

The absence of an official vegan certification from Kosas might be due to the potential cross-contamination of vegan and non-vegan ingredients during the manufacturing process. Many brands choose not to label their products as vegan to avoid any confusion or potential ethical concerns related to cross-contamination.


While Kosas prioritizes clean beauty and ethical practices, not all of their products are vegan. Some of their formulations may contain animal-derived ingredients like lanolin, carmine, or honey. It’s essential to review the ingredient list provided by Kosas to determine if a specific product aligns with your vegan lifestyle.

However, Kosas is certified by the Leaping Bunny Program, ensuring their products are cruelty-free and not tested on animals. While this certification doesn’t guarantee a product is vegan, it demonstrates the brand’s commitment to ethical practices. If vegan certification is a crucial factor for you, exploring other brands that offer explicit vegan labeling might be the best option.
