Determination of Total Free Alkalinity in Soaps: Quality and Safety

Why Determination of Total Free Alkalinity in Soaps?

Determination of Total Free Alkalinity in Soaps: Quality and Safety

Soap is a product frequently used for cleaning in daily life and its content can directly affect the health of the user. Free alkalinity in soaps is an important measure of product quality and safety. Free alkalinity can affect the pH value of soap and cause side effects such as skin irritation, so it must be checked with an accurate and reliable analysis.

What is Total Free Alkalinity and why is it important?

Free alkalinity is an indicator of overly basic (alkaline) ingredients in the soap formulation. During the production of soaps, saponification occurs when oils react with basic substances (usually sodium hydroxide or potassium hydroxide). As a result of this reaction, free alkaline substances may sometimes remain in the soap. In this case, if the free alkalinity is high, the pH of the soap will also increase, which can increase the risk of skin irritation.

Controlling the amount of free alkalinity is essential to ensure soap quality and protect consumer safety. High alkalinity levels can lead to soap being too harsh for the skin and irritation during use.


Importance of Free Alkalinity Determination for Product Quality and Consumer Safety

Free alkalinity determination directly affects product quality and user safety. Soaps containing excess alkali can cause skin irritation and in some cases trigger allergic reactions. Therefore, free alkalinity determination of soaps is a critical step to ensure product quality.

Advantages provided by free alkalinity determination:

  1. Skin Friendly Soap Production: Free alkalinity control makes soaps skin-friendly. This is especially important for babies and those with sensitive skin.
  2. Accurate Labeling and Reliability: The pH value indicated on the product label is verified and reliable information is provided to consumers.
  3. Legal Compliance and Safe Product Use: With free alkalinity determination, manufacturers comply with legal regulations and offer reliable products to the market.
