Improving Cream Absorption and Eliminating White Cast

The white cast you are experiencing with your cream formula is primarily caused by the emulsifiers Cetearyl Alcohol and Glyceryl Monostearate at the concentrations used. As the staff mentioned, this is a common characteristic of these ingredients and the white film usually disappears after rubbing.

Adding penetration enhancers can help active ingredients absorb better into the skin, but they will not eliminate the white cast caused by your current emulsifier system. Examples of penetration enhancers include Tetrahydropiperine and TransMoist™.

To address the white cast and improve the texture for easier spreading and faster absorption, the most effective approach is to change the emulsifier system in your formula. Here are a couple of options to consider, keeping in mind your goal of reducing cost:

• Sucrose Cream Maker™: This is a natural-based emulsifier known for significantly reducing visible whitening on the skin and providing a lightweight, non-oily feel with improved absorption. It creates a silky texture. Note that this emulsifier typically requires heating during the mixing process.
• Easy Cream Maker™: This emulsifier is generally more cost-effective and can be used without heat, which simplifies the process. However, it might result in a slightly heavier texture compared to other options and has limitations regarding the percentage of oil and compatibility with electrolytes. Your current oil percentage (5% IPM) is within its typical usage range.

Additionally, slightly increasing the proportion of the oil phase in your formula can sometimes help to reduce the appearance of the white cast.

Choosing a different emulsifier system is key to achieving a cream that absorbs quickly without leaving a white residue.
