Mixing Oil Soap with Glycerin Bar Soap

Regarding the question about mixing Oil Soap with glycerin soap to make a solid bar soap, it is not recommended to mix the two types together due to their significantly different properties and uses.

Reasons why mixing Oil Soap with glycerin soap is not recommended:

• pH Level: Glycerin bar soap (ID 143) has a high alkalinity (high pH), which can easily irritate dry skin. It is therefore more suitable for normal to oily skin.
• Properties and Usage: Oil Soap (ID 677) is specifically developed to have a slightly acidic pH and can incorporate a large amount of oil. This makes it suitable for dry skin as a liquid soap, providing gentle cleansing while moisturizing the skin. However, it is generally not suitable for oily skin.

Therefore, mixing Oil Soap, which is a liquid soap base with specific properties for dry skin, with glycerin bar soap, which has different properties, higher alkalinity, and is suitable for other skin types, is not advisable and not recommended.
