Soap INS Value: Ideal Range (136 – 165)

Soap INS Value: When it comes to making or selecting soap, one of the most crucial metrics to consider is the INS Value. This value plays a significant role in determining the hardness, lathering capability, and overall skin benefits of the soap. Ideally, the INS value of soap should fall within the range of 136 to 165. In this blog, we’ll dive deep into what INS value means, why it’s essential, and how it affects the quality of the soap you use.

What is the INS Value in Soap?

The INS value is a specific index that measures the quality of the fatty acids and oils used in soap. It is calculated by combining the Iodine Value and the Saponification Value (SAP Value). The INS value helps to determine the soap’s hardness, its ability to create a rich lather, and how well it moisturizes the skin. Ideally, the INS value of soap should be between 136 and 165 to ensure a well-balanced, effective soap.

Why is INS Value Important?

The INS value is essential because it directly influences the durability, lathering ability, and skin-friendliness of the soap. Here are some reasons why the INS value is important:

1. Soap Hardness:
   • A higher INS value results in a harder, longer-lasting soap bar that doesn’t dissolve too quickly.
2. Lathering Capability:
   • A soap with the ideal INS value will produce a rich and creamy lather, making the cleansing process more enjoyable and effective.
3. Skin Care and Moisturizing:
   • Soaps with the right INS value help maintain the skin’s natural moisture, preventing dryness and leaving the skin feeling soft and smooth.

Ideal INS Range for Soap (136 – 165)

The ideal INS value for soap is between 136 and 165. If the INS value falls below 136, the soap will be too soft and may not last as long. On the other hand, if the INS value is above 165, the soap may become too hard and could potentially dry out the skin. A soap with an INS value in the ideal range ensures that the soap is both durable and gentle on the skin.

How is the INS Value Determined?

The INS value is determined by the types of oils and fatty acids used in the soap formulation. Below are some ingredients that affect the INS value:

1. Cocoa Butter:
   • Cocoa butter increases the INS value, making the soap harder and more long-lasting.
2. Olive Oil:
   • Olive oil adds softness to the soap and improves its ability to create a rich lather.
3. Coconut Oil:
   • Coconut oil increases the INS value, helping the soap produce more lather and become more durable.
4. Palm Oil:
   • Palm oil helps make the soap harder and more durable, increasing its overall INS value.

Choosing Soap Based on INS Value

If you have sensitive or dry skin, choosing a soap with an INS value between 136 and 165 is ideal. This range ensures that the soap will maintain your skin’s natural moisture while still providing a good lather and long-lasting use. Additionally, soaps within this range are perfect for everyday use as they strike the perfect balance between hardness and moisturizing ability.

Conclusion

The INS value of soap is a crucial factor that influences the soap’s hardness, durability, and ability to moisturize the skin. The ideal range of 136 to 165 ensures that the soap is both effective and long-lasting, making it suitable for a variety of skin types. By selecting a soap with the right INS value, you can ensure that your skin remains soft, smooth, and well-hydrated.
