Modifying Giffarine Cooling Shower Gel Formula for Mature Skin and Other Formulation Questions

Asked by: donotgiveup12345601 On: March 04, 2014 Product Type: Cosmetics

Question

I want to modify a Giffarine Cooling Shower Gel formula. The ingredients include Menthol, Methyl lactate, Triclosan, colorants, fragrance components (Linalool, Hexyl cinnamal, Benzyl salicylate, Limonene, Butylphenyl methylpropional, Citronellol, Coumarin, Eugenol), and Glycerin.

I want to remove Triclosan, colorants, and fragrance, but keep the cooling effect (I couldn't find Menthol). I also want to add nourishing ingredients for mature skin (55 years old). What ingredients should I remove and what should I add?

Also, regarding a previous shampoo formula, can I use it as a shower gel by omitting water, preservatives, and Cetrimonium chloride, and increasing Cocowash?

Separately, can `Encapsulated salicylic acid 5%` be put in `glycerin`, and can I use `lauryl glucoside 5%` in a facial wash?

Answer

Modifying the Giffarine Cooling Shower Gel Formula

Based on the ingredients you listed and your goal to simplify the formula while keeping it cool and adding nourishment for mature skin, here's a breakdown:

Ingredients to Consider Removing

  • Triclosan: This is an antibacterial agent. For a standard shower gel for personal use, it is generally not considered essential and can be removed.
  • Colorants (สี): These are purely for aesthetic purposes and do not contribute to the product's performance or skin benefits. They can be safely removed.
  • Fragrance components (Linalool, Hexyl cinnamal, Benzyl salicylate, Limonene, Butylphenyl methylpropional, Citronellol, Coumarin, Eugenol): These provide the scent. If you prefer an unscented product or want to avoid potential fragrance sensitivities, you can remove these. If you want a scent, you would keep them or replace them with a different fragrance.

Keeping the Cooling Effect

The cooling sensation in the original formula comes from Menthol and Methyl lactate. You mentioned not finding Menthol. Methyl lactate is already in the list you provided, so ensure you include this ingredient.

If you need additional or alternative cooling agents, consider:

  • Menthyl Lactate: This provides a cooling effect similar to menthol but is often considered milder.
  • CoCool™ (Menthol+Menthyl Lactate): This is a blend that provides a cooling sensation.

You can use Methyl lactate, Menthyl Lactate, or CoCool™ to achieve the desired cooling level.

Adding Nourishing Ingredients for Mature Skin (55 years old)

Mature skin can benefit from ingredients that provide hydration and soothing properties. Good additions to a shower gel formulation include:

  • Panthenol (Vitamin B5): This ingredient is an excellent humectant, helping the skin retain moisture. It also has soothing and skin barrier-supporting properties, which are beneficial for drier, mature skin. It can help reduce inflammation and support skin healing.
  • Allantoin: Known for its soothing and skin-conditioning abilities, Allantoin helps reduce irritation and promotes skin regeneration. It can make the shower gel feel gentler on the skin.
  • Glycerin: This is already in the original formula and is a very effective humectant. Ensuring a sufficient amount of Glycerin helps draw moisture to the skin during cleansing.

While shower gels are rinse-off products, including these ingredients can still provide a noticeable improvement in skin feel and comfort, especially for mature skin.

Regarding the Second Formula (from Previous Conversation)

You asked about using the shampoo formula from the previous conversation as a shower gel, omitting water, preservatives, and Cetrimonium chloride, and increasing Cocowash.

  • Omitting Water: A shower gel requires water as the primary base to function correctly, create lather, and have the right texture. Omitting water from that formula would likely result in a very thick, unusable product.
  • Preservatives: As the staff member mentioned, even with a pump bottle, a water-based product (like a shower gel) absolutely requires a preservative system to prevent microbial growth (bacteria, mold, yeast). The humidity in a bathroom and potential introduction of water during use make preservatives essential for safety and shelf life.
  • Cetrimonium Chloride: As noted in the previous conversation, Cetrimonium chloride is typically used in hair products (shampoos, conditioners) for conditioning and detangling. It is not necessary for a shower gel for the body.
  • Increasing Cocowash: While increasing Cocowash would increase the amount of surfactant, Cocowash is very mild. As the staff suggested, for effective body cleansing, it is better to combine Cocowash with another, perhaps slightly stronger but still gentle, co-surfactant like Lauryl Glucoside or Coco-Betaine. This blend will provide better cleansing power while still being gentle.

In summary, while you can adapt the second formula, you would need to include water, add a preservative, omit Cetrimonium chloride, and ideally use a blend of surfactants like Cocowash and Lauryl Glucoside or Coco-Betaine for effective cleansing.
