What Is Ammonium Lauryl Sulfate?

Ammonium lauryl sulfate, or ALS, is a detergent and surfactant that is used in many cleaning products. It is a white, powdery substance that is soluble in water. ALS is produced by combining lauryl alcohol with sulfuric acid. The resulting mixture is then neutralized with ammonia to produce ammonium lauryl sulfate. This substance has a number of benefits for cleaning products. It helps to create foam, which can trap dirt and debris; it also helps to break down oils and greases, making them easier to remove. 

How Does ALS Work in Cosmetics?

Ammonium lauryl sulfate is a surfactant, which means it helps to reduce the surface tension of water. This enables it to bind to dirt and oil, making them easier to remove during the washing process. In addition, ammonium lauryl sulfate also helps to create foam. When added to water, it forms tiny bubbles that help to lift dirt and grime away from surfaces. As a result, ammonium lauryl sulfate is an effective cleanser that can be used in a variety of applications, from shampoo to laundry detergent.


Ammonium lauryl sulfate (ALS) is a common ingredient in many personal care products, including shampoo, toothpaste, and soap, just like sodium lauryl sulfate. However, the two have some important differences. Both ALS and SLES are derived from coconut oil, but ALS is manufactured using fewer processing steps than SLES. As a result, ALS is less harsh on the skin and hair. In addition, ALS is less likely to cause irritation and allergies than SLES. For these reasons, ALS can be used in gentle personal care products, such as baby shampoo. But does it mean it’s completely safe?

The Safety of Ammonium Lauryl Sulfate

When it comes to skin care products, you may find that products containing ALS are likely to cause dryness, redness, and itchiness. In fact, some people may experience an allergic reaction to ALS. If you have sensitive skin, you may want to avoid products that contain this ingredient. However, if you do use products with ALS, be sure to moisturize your skin afterwards to help prevent irritation.

In general, it is advised that if you have sensitivities or conditions like eczema or psoriasis, you may want to avoid products that contain ammonium lauryl sulfate. However, if you don’t, and the product also contains other moisturizing ingredients like glycerin or plant-based oils, it may not be as drying. Ultimately, it’s a good idea to read labels carefully and test products on a small area of skin before using them regularly.

Is ALS Comedogenic?

There have been claims that ALS is comedogenic, meaning that it can block pores and cause acne. There is limited scientific evidence to support this claim, but some studies have shown that ALS can increase the permeability of the skin. 

Is ALS Carcinogenic?

Some people have raised concerns about the safety of ALS, claiming that it may be carcinogenic. However, there is no scientific evidence to support this claim. So, while it is important to be careful about the ingredients in your personal care products, ALS does not appear to be the cause for that big of a concern.

Where Does ALS Come From?

Ammonium lauryl sulfate is a surfactant that can be derived from either natural or synthetic sources. When derived from natural sources such as coconut oil, it is considered to be organic. However, when derived from synthetic sources such as petroleum, it is considered to be synthetic. It is also relatively inexpensive to produce. While ALS derived from synthetic sources may be more affordable, many consumers prefer products that contain only organic ingredients.

Studies have also shown that ALS is biodegradable, meaning it can be broken down by bacteria and other microorganisms. This process helps to reduce the amount of ALS that enters the environment.

The Bottom Line

So, is ammonium lauryl sulfate safe? It’s not dangerous, for sure! But, if you have sensitive skin, you may want to avoid using products that contain it. There is no reason to discard a product just because it contains ALS, especially if it has some moisturizing ingredients that counterbalance it. Ultimately, it’s a good idea to test products on a small area of skin before using them all over your body. Thanks for reading!
