What is Stearic AcidStearic Acid is one of the most common saturated fatty acids found in nature primarily through animal and vegetable fats. It is used in cosmetic and skincare products around the world.
We use stearic acid in our hair and skincare line of products because it is a surfactant and emulsifying agent. It helps other emollients bind together and stabilizes the formula that contain fragrances. Stearic Acid can moisturize the skin and it can protect the hair shaft by coating it without leaving the hair feeling heavy or looking dull.
Why do we use Stearic Acid
Is Stearic Acid safe to use? Is it nontoxic?
The triple pressed stearic acid that we use is safe and not toxic to the environment. However, if using pure stearic acid it could cause skin, eye and respiratory irritation. According to a NOAA report there is no current information available if it is toxic to aquatic life. Some research has been done and documented about the oral toxicity of stearic acid. Since we do not deal in food items, I have not added that information to this article.
Rustic Strength uses stearic acid in our lotions and conditioners to help with moisture retention and protection of the hair shaft. It is widely accepted material in cosmetics and food. Stearic acid is readily biodegradable with little to no toxicities.
If you have any questions regarding this or any other chemical we use feel free to reach out to email@example.com We would be more than happy to answer your questions.
We invite you to do your own research!
Scientific journals and articles are the foundation of evidence-based decisions at Rustic Strength. Blogs can provide helpful information. However, if it can not cite scientific articles, its claims stand on little.
