Facial Cream Formula Suitability for Eye Area and Mixing Instructions

ถามโดย: thananyakraphong เมื่อ: November 14, 2018 ประเภทผลิตภัณฑ์: เครื่องสำอาง

คำถาม

I have dry, dehydrated skin with freckles, and I am 37 years old. I want to make a facial cream using the following formula:

Formula 1:

  • Activated Resorcinol 1%
  • MSH White 4%
  • Repair Activator 10%
  • Pep-Coll 3%
  • MOIST72 5%
  • WaterLock 2%
  • Paeonia Preserve 0.5%
  • Distilled Water (remaining portion)
  • Luxury Cream Maker 1.5%

My questions are:

  1. Can this cream be used around the eye area?
  2. Previously, when I added Pro Polymer at 0.5% to a formula, there was a strong smell similar to alcohol. Why did this happen?
  3. Could you please provide the mixing steps for this formula?
  4. For Paeonia Preserve 0.5%, should the calculation be based on the total weight of the formula or just the weight of the distilled water?

Facial Cream and Eye Area Suitability

Based on the formula you provided for a facial cream, here's an analysis regarding its suitability for the eye area, the issue with the Pro Polymer smell, and mixing instructions.

Suitability for the Eye Area

The formula contains several active ingredients aimed at addressing skin concerns like freckles and wrinkles, such as Activated Resorcinol and MSH White. While these ingredients are beneficial for the face, the skin around the eyes is much thinner and more sensitive. Activated Resorcinol, especially at a 1% concentration, can potentially cause irritation in this delicate area. Therefore, this specific cream formula is not recommended for use around the eyes. It is best to use a dedicated eye cream formulated for the sensitive eye area.

Issue with Pro Polymer Smell

You mentioned experiencing a strong alcohol-like smell when using Pro Polymer at 0.5% in a previous formula. Looking at the ingredients in your current formula, Paeonia Preserve contains Ethyl alcohol as part of its composition. It is highly likely that the alcohol-like smell you detected came from the Paeonia Preserve rather than the Pro Polymer. Pro Polymer itself is a powder and does not typically have an alcohol scent.

Mixing Instructions for Your Formula

Here are the steps to mix your facial cream formula (assuming you will include a suitable oil in the formula):

Ingredients:

  • Activated Resorcinol 1%
  • MSH White 4%
  • Repair Activator 10%
  • Pep-Coll 3%
  • MOIST72 5%
  • WaterLock 2%
  • Paeonia Preserve 0.5%
  • Distilled Water (to make up 100%)
  • Luxury Cream Maker 1.5%
  • Suitable cosmetic oil (e.g., LipidSoft) - You need to add this ingredient to your formula.

Instructions:

  1. Prepare Water Phase: In a clean container, combine the Distilled Water, Repair Activator, MOIST72, WaterLock, Paeonia Preserve, and Luxury Cream Maker. Stir or blend the mixture until the Luxury Cream Maker is fully dissolved and the water phase begins to thicken into a consistent base. Gentle warming (around 50-60°C) can help the Luxury Cream Maker dissolve more easily, but avoid excessive heat.
  2. Prepare Oil Phase: In a separate container, combine your chosen cosmetic oil with MSH White. Heat this mixture to approximately 80°C and stir continuously until the MSH White powder is completely dissolved and the oil is clear. Remove from heat and allow the oil phase to cool down completely to room temperature (below 40°C). Once cooled, add Activated Resorcinol to this oil phase and stir until it is fully dissolved. Activated Resorcinol is sensitive to heat, so ensure the oil is cool before adding it.
  3. Combine Phases: Slowly pour the cooled oil phase into the water phase while continuously stirring or blending the mixture. Continue mixing until the oil and water phases are fully combined and a smooth, uniform cream is formed.
  4. Add Final Ingredient: Add Pep-Coll to the cream base. Stir until the Pep-Coll is evenly distributed throughout the cream. Ensure the cream's temperature is below 40°C when adding Pep-Coll.
  • Note on Paeonia Preserve: The usage rate for Paeonia Preserve is typically calculated based on the total weight of your final formula.
  • Recommendation for Stability: To help prevent discoloration of the Activated Resorcinol in your formula, it is highly recommended to include Disodium EDTA at a concentration of 0.2% in your water phase (Step 1).

Follow these steps carefully to create your facial cream.
