Analysis of Your Cream Formulation

You've created a cream using Light Cream Maker, Placenta extract, Pearl extract, Vitamin E, Phenoxyethanol, and Lanolin, and experienced a temporary warming sensation. Let's look at the potential causes.

Based on the properties of the ingredients:

• Light Cream Maker and Lanolin at 2% are generally not known to cause warming or stinging sensations on the skin.
• Placenta extract and Pearl Powder descriptions do not indicate that they cause a warming feeling.
• Vitamin E (Tocopheryl Acetate) at 1% is within the typical usage range, although concentrations above 0.5% can sometimes cause a sticky feeling. Warming is not a commonly reported effect for Vitamin E itself.
• Phenoxyethanol is a preservative. Preservatives, in general, can sometimes cause temporary skin irritation or sensations like warming, especially at higher concentrations or in individuals with sensitive skin. You used Phenoxyethanol (Extra Pure) at 1%, which is at the maximum recommended usage rate for this type. Another user in the forum also reported a similar warming sensation when using Phenoxyethanol SA. This suggests that Phenoxyethanol is the most likely ingredient causing the initial warming feeling you experienced.

The fact that the warming sensation subsided after a while could indicate a temporary, mild irritation or that your skin adjusted to the ingredient.

Regarding your question about Mild Preserved Eco: If you switch to using Mild Preserved Eco with Light Cream Maker, you do not need to pre-mix it with Propylene Glycol. According to the information available, you can add Mild Preserved Eco in the final step of your formulation, or mix it with the oil phase or Light Cream Maker before combining with the water phase.
