LDS and Other Specialty Salts – The Expensive Specialists
Beyond Sodium: Why Other Salts Exist
So far, we’ve talked about sodium salts.
Sodium is cheap. Sodium is common.
But sometimes, sodium isn’t the best choice.
That’s when we use other salts.
LDS: Lithium Dodecyl Sulfate
What’s special about lithium?
LDS dissolves incredibly fast.
Even in cold water.
It also has a lower freezing point.
Where is it used?
- Specialty cleaning products
- Low-temperature applications
- Some scientific research
The catch?
Lithium is expensive.
LDS costs 5-10 times more than SLS.
Only use it when you truly need its special properties.
ALS: Ammonium Lauryl Sulfate
What’s special about ammonium?
ALS is milder than SLS on skin.
It also produces very stable foam.
Where is it used?
- Shampoos (especially “gentle” formulas)
- Facial cleansers
- Bubble baths
The trade-off?
ALS has a slight ammonia smell.
Good products mask this with fragrance.
Also slightly more expensive than SLS.
AESA: Ammonium Lauryl Ether Sulfate
This is the ammonium version of SLES.
Think: SLES but milder.
Where is it used?
- Baby shampoos
- Sensitive skin products
- Premium personal care
Cost?
More than SLES, less than LDS.
A good middle option for mild products.
MLS: Magnesium Lauryl Sulfate
What’s special about magnesium?
Very mild. Very gentle.
Creates a specific foam texture.
Where is it used?
- High-end facial cleansers
- Specialty cosmetics
Availability?
Harder to find than other salts.
Fewer manufacturers make it.
When to Consider Specialty Salts
Ask yourself these questions:
- Does my product need to work in cold temperatures?
→ Consider LDS - Do I need extra mildness for sensitive skin?
→ Consider ALS or AESA - Am I making a premium product where cost is less important?
→ Consider MLS or AESA - Is my main concern keeping costs low?
→ Stick with sodium salts (SLS, SLES)
Buying Tips for Specialty Salts
Don’t buy more than you need.
These salts are expensive.
Sitting in your warehouse, they can absorb moisture or degrade.
Buy for 1-2 months of production, not more.
Verify the supplier carefully.
Fewer factories make specialty salts.
Fake products are more common.
Ask for third-party test reports.
Consider blending.
Sometimes you don’t need 100% specialty salt.
Mixing 20% ALS with 80% SLS can give you mild performance at lower cost.
The Bottom Line
Specialty salts solve specific problems.
Cold temperatures. Extra mildness. Unique foam feel.
But they cost more. Sometimes much more.
Use them when the application demands it.
For everyday products, sodium salts work just fine.
Performance and Applications
