Questions on Formulation, Packaging, High-Concentration Peels, and Irritation Reduction

Asked by: plantycoon On: February 12, 2013 Product Type: Cosmetics

Question

I have several questions regarding product formulation, packaging, and ingredient usage:

  1. Why are not all ingredients included in ready-to-use products?
  2. Why not try creating bases that can dissolve insoluble ingredients?
  3. When will the silicone base (anhydrous) be available, and can you provide a formula for anhydrous Vitamin C?
  4. Why are vacuum packaging bottles not sold? I believe they would help reduce product exposure to air and are better than pump bottles.
  5. Regarding the base PEG-240/HDI Copolymer Bis-Decyltetradeceth-20 Ether, I have tried it myself and it is very good. Can you consider selling it?
  6. Can you provide formulas for mixing various sunscreen ingredients?
  7. In the ready-to-use section, some ingredients like ceramide are listed, but there is no option to select the percentage. Why are they listed if the percentage cannot be specified?
  8. Can you provide formulas for Salicylic Acid 20% and Lactic Acid 80%? I would like to try doing a chemical peel at home.
  9. Can you recommend formulas to reduce side effects from using Vitamin A acids?
  10. Can you recommend formulas to reduce side effects from using Benzoyl Peroxide (BP)?

Answer

Hello! I will answer your questions and concerns based on the information discussed in this thread.

Answer to your questions:

  1. Why not include all ingredients in ready-to-use products? and 2. Why not try creating bases for insoluble ingredients?

    • These specific questions were not directly answered in this thread. It is understood that there might be various factors preventing all ingredients from being included in ready-to-use products, and developing bases for insoluble substances might be complex.

  2. Regarding silicone base (anhydrous) availability and anhydrous Vit C formula: Staff mentioned that this topic has been discussed in previous threads. It is recommended to search the webboard for more information.

  3. Regarding vacuum packaging bottles: Staff consulted the sales department and received feedback that vacuum packaging bottles are too expensive compared to their value. Also, regular pump bottles do not allow air into the product.

  4. Regarding the PEG-240/HDI Copolymer Bis-Decyltetradeceth-20 Ether base: There was a diverse discussion and opinions about this base. Staff requested you to compare it with other bases and provide a review to share your experience. If this base is indeed good, Staff is willing to inform the sales department to consider importing it.

    • Other users commented that the main property of this base is its memory gel characteristic (shape recovery), but the non-sticky feel might come from other ingredients in certain finished product formulas, not the base itself. Observations were also made regarding the value of ingredients in finished products using this base.

  5. Regarding mixing sunscreen ingredients: Staff mentioned that mixing sunscreen ingredients has been discussed in other threads.

  6. Regarding ready-to-use products with ingredients like ceramide but no percentage selection: Staff clarified that if there is no option to select the percentage, it means the item is out of stock. The system only shows options for items that are currently in stock.

  7. Regarding formulas for Salicylic Acid 20% and Lactic Acid 80% for home chemical peel: Both other users and Staff strongly advised against performing high-concentration chemical peels like Salicylic Acid 20% or Lactic Acid 80% at home. Using high-concentration acids is dangerous and should only be done under the supervision of a dermatologist.

    • Staff added that Salicylic Acid 20% is not used for facial skin but for other skin issues like warts, to aid in peeling.

  8. Regarding reducing side effects from Vitamin A acids and 10. Regarding reducing side effects from Benzoyl Peroxide (BP): The advice for reducing side effects from Vitamin A acids and Benzoyl Peroxide is similar.

    • Ways to reduce irritation:
      • Increase skin hydration.
      • Use soothing ingredients such as Green Tea, Licorice, Bisabolol, Allantoin, and Willow Bark.
      • If irritation persists, reduce the frequency of use, for example, every other day or every two days.
      • Consider reducing the concentration of the product used. If the skin cannot tolerate high concentrations, using a suitable concentration that allows for continuous and consistent use is often more effective. Research indicates that using higher concentrations does not always yield better results and can instead increase irritation.

Hope this information is helpful.
