When it comes to personal care products, few ingredients have sparked as much controversy as sulfates. Sodium Lauryl Sulfate (SLS) and Ammonium Lauryl Sulfate (ALS) are two of the most commonly used sulfates in shampoos, body washes, and toothpastes. While they share some similarities, they also have distinct differences. In this article, we’ll delve into the world of sulfates and explore whether Ammonium Lauryl Sulfate is better than SLS.
What are Sulfates?
Sulfates are a type of surfactant, short for surface-active agent. They work by reducing the surface tension of water, allowing it to penetrate more easily into the skin and hair. This makes sulfates excellent cleansing agents, capable of removing dirt, oil, and other impurities. Sulfates are also known for their ability to create a rich, creamy lather, which is why they’re often used in personal care products.
The Difference Between SLS and ALS
Sodium Lauryl Sulfate (SLS) and Ammonium Lauryl Sulfate (ALS) are both derived from lauryl alcohol, a fatty alcohol found in coconut oil and palm kernel oil. However, they differ in their chemical composition and properties.
SLS is a sodium salt of lauryl sulfate, while ALS is an ammonium salt of lauryl sulfate. This difference in chemical structure affects their pH levels, with SLS having a higher pH than ALS. SLS typically has a pH range of 5.5-6.5, while ALS has a pH range of 5.0-6.0.
pH Levels and Skin Irritation
The pH level of a product can have a significant impact on skin irritation. A product with a high pH can disrupt the skin’s natural barrier function, leading to irritation and dryness. Since SLS has a higher pH than ALS, it may be more likely to cause skin irritation, especially for those with sensitive skin.
The Benefits of Ammonium Lauryl Sulfate
So, is Ammonium Lauryl Sulfate better than SLS? Let’s explore some of the benefits of ALS:
- Gentler on skin: ALS has a lower pH than SLS, making it a more gentle option for sensitive skin.
- Less stripping: ALS is less likely to strip the skin and hair of their natural oils, resulting in a more moisturized and nourished feel.
- Improved lather: ALS creates a rich, creamy lather that’s similar to SLS, but with a more gentle and non-stripping formula.
The Drawbacks of Ammonium Lauryl Sulfate
While ALS has its benefits, it’s not without its drawbacks. Here are some of the potential downsides of ALS:
- Less effective at removing dirt and oil: ALS may not be as effective at removing dirt and oil as SLS, which can be a problem for those with oily skin or hair.

The Benefits of Sodium Lauryl Sulfate
While ALS has its benefits, SLS is still a widely used and effective ingredient. Here are some of the benefits of SLS:
- Excellent cleansing properties: SLS is excellent at removing dirt, oil, and other impurities from the skin and hair.
- Rich lather: SLS creates a rich, creamy lather that’s popular in personal care products.
- Cost-effective: SLS is generally less expensive than ALS, making it a more attractive option for manufacturers.
The Drawbacks of Sodium Lauryl Sulfate
While SLS has its benefits, it’s not without its drawbacks. Here are some of the potential downsides of SLS:
- Harsh on skin: SLS can be harsh on skin, especially for those with sensitive skin.
- Strips natural oils: SLS can strip the skin and hair of their natural oils, leading to dryness and irritation.
Conclusion
So, is Ammonium Lauryl Sulfate better than SLS? The answer depends on your individual skin and hair type. If you have sensitive skin or hair, ALS may be a better option due to its gentler and less stripping formula. However, if you have oily skin or hair, SLS may be a better option due to its excellent cleansing properties.
Ultimately, the choice between ALS and SLS comes down to your individual needs and preferences. By understanding the benefits and drawbacks of each ingredient, you can make an informed decision about which one is best for you.
| Ingredient | pH Level | Gentleness | Cleansing Properties | Lather |
|---|---|---|---|---|
| Sodium Lauryl Sulfate (SLS) | 5.5-6.5 | Harsh | Excellent | Rich and creamy |
| Ammonium Lauryl Sulfate (ALS) | 5.0-6.0 | Gentle | Good | Rich and creamy |
By considering the pH level, gentleness, cleansing properties, and lather of each ingredient, you can make an informed decision about which one is best for you. Whether you choose ALS or SLS, remember to always read the label and look for products that are formulated for your individual skin and hair type.
What is Ammonium Lauryl Sulfate (ALS) and how does it differ from SLS?
Ammonium Lauryl Sulfate (ALS) is a type of surfactant commonly used in personal care products, such as shampoos, body washes, and toothpastes. It is similar to Sodium Lauryl Sulfate (SLS) in terms of its cleansing properties, but it has some distinct differences. ALS is generally considered to be milder and less irritating to the skin and scalp compared to SLS.
The main difference between ALS and SLS lies in their pH levels. ALS has a higher pH level than SLS, which makes it less likely to disrupt the skin’s natural pH balance. Additionally, ALS is often used in combination with other surfactants to create a gentler cleansing formula. This makes ALS a popular choice for products marketed as “sensitive skin friendly” or “gentle.”
Is Ammonium Lauryl Sulfate better than SLS for skin care?
Ammonium Lauryl Sulfate (ALS) is generally considered to be a better option than SLS for skin care due to its milder properties. ALS is less likely to strip the skin of its natural oils, which can lead to dryness and irritation. Additionally, ALS is often used in lower concentrations than SLS, which can further reduce the risk of irritation.
However, it’s essential to note that everyone’s skin is different, and what works for one person may not work for another. Some people may still experience irritation or allergic reactions to ALS, even at low concentrations. If you have sensitive skin, it’s always a good idea to do a patch test before using a new product containing ALS.
Can I use Ammonium Lauryl Sulfate if I have sensitive skin?
If you have sensitive skin, you may be able to use Ammonium Lauryl Sulfate (ALS) without any issues. However, it’s crucial to exercise caution and follow some guidelines. Look for products that use ALS in combination with other gentle surfactants, and opt for products that are labeled as “hypoallergenic” or “fragrance-free.”
When using a product containing ALS, start with a small patch test to check for any adverse reactions. Apply a small amount of the product to a discreet area of your skin and wait 24 hours to see if any irritation occurs. If you experience any redness, itching, or burning, discontinue use and try a different product.
Is Ammonium Lauryl Sulfate safe for the environment?
