Hey there, curious minds! If the question, “Is E328 Halal?” has ever crossed your mind, you’ve landed on the right page. Together, we’ll unravel the mysteries of E328 and determine its Halal status. Let’s get started!

Key Takeaways

📌 E328, also known as Ammonium lactate, is a substance used in food as an acidity regulator. It’s found in various food products.
📌 E328 is generally safe for consumption, but its Halal (permissible) or Haram (forbidden) status depends on the source of the lactic acid used to make it. If the lactic acid comes from a Halal source and the production process is clean, it’s considered Halal.
📌 In most cases, E328 is used in skin creams and lotions due to its moisturizing properties.

What is E328?

E328, also known as Ammonium lactate, is a compound often used as a food additive. It’s primarily used as an acidity regulator in various food products. But what exactly is it?

Chemical Structure

e328 ammonium lactate chemical formula

E328, or Ammonium lactate, has a chemical formula of C3H9O3N. It’s the ammonium salt of lactic acid and is often found in lotions and skin creams due to its moisturizing properties.

What Is E328 Made From?

E328 is synthesized by neutralizing lactic acid with ammonium hydroxide. Lactic acid can be derived from various sources, including bacterial fermentation of carbohydrates. The source of the lactic acid and the method of production can influence whether E328 is considered Halal.

Possible Side Effects

Some possible side effects of ammonium lactate:

Common side effects

  • Stinging, burning, and redness at the application site
  • Mild dryness or skin irritation after use
  • Bruising or discoloration of treated skin

Less common side effects

  • Irritation, eczema, petechiae, dryness, and hyperpigmentation
  • Darkening/lightening of the skin, small red dots on the skin
  • Skin peeling, rash, itching, and skin irritation (especially on the face)
  • Increased sensitivity to the sun

Regulations and Guidelines

Ammonium lactate is not commonly used as a food additive, but rather as a topical medication for skin conditions. Its use in food is subject to regulations and guidelines for food additives.

In the United States, ammonium lactate is not approved as a food additive by the Food and Drug Administration (FDA). However, it is used as a skin moisturizer lotion to treat dry, scaly, itchy skin. The FDA regulates the use of ammonium lactate as a drug and has issued guidance on its use as a topical lotion.

Dosage and Administration

Ammonium lactate is for external use only and should not be used for any disorder other than for which it was prescribed. If the condition worsens with treatment, therapy should be discontinued promptly. 

Ammonium lactate makes skin more sensitive to sunlight, and skin is more likely to sunburn. Therefore, those who are using it should avoid exposure to sunlight or artificial UV rays, such as sunlamps or tanning beds.

Is E328 Halal or Haram?

The Halal status of E328 depends on its source and the method of production. If the lactic acid used to produce E328 is derived from a Halal source and the production process does not involve any Haram (forbidden) substances, then E328 can be considered Halal.

Unfortunately, the halal status of the majority of lactic acid sources used as an ingredient in E328 remains uncertain, which in turn places the legal status of E328 in the doubtful or questionable category.
