Sunscreen Cream Formulation Without Specific Emollients

คำถาม

I would like a sunscreen cream formulation. The formula I have is:

  • Benzophenone-3 7%
  • ETHYLHEXYL METHOXYCINNAMATE 7%
  • Titanium Dioxide 6%
  • Cetearyl Alcohol 3.5%
  • Glycerol monostearate 3.5%
  • Ceteareth-25 1%
  • Isopropyl palmitate 1.5%
  • Caprylic/capric triglyceride 1.5%
  • Polyethylene glycol 1%
  • Ethyl paraben 0.5%
  • Distillate water 67.5%

Can I form a sunscreen cream from the formula above? The original formula included Argan Oil PEG-8 esters, shea butter oleyl esters, and Isocetyl stearate, but the percentages were not specified. I am unsure if the cream can be formed if these ingredients are omitted.

Sunscreen Cream Formulation Analysis

Based on the formula provided:

  • Benzophenone-3 (7%)
  • ETHYLHEXYL METHOXYCINNAMATE (7%)
  • Titanium Dioxide (6%)
  • Cetearyl Alcohol (3.5%)
  • Glycerol monostearate (3.5%)
  • Ceteareth-25 (1%)
  • Isopropyl palmitate (1.5%)
  • Caprylic/capric triglyceride (1.5%)
  • Polyethylene glycol (1%)
  • Ethyl paraben (0.5%)
  • Distillate water (67.5%)

This formula contains the essential components needed to form a basic cream emulsion. The combination of Cetearyl Alcohol, Glycerol monostearate, and Ceteareth-25 acts as the emulsifier and thickening system, which is crucial for binding the oil and water phases together to create a stable cream structure.

The ingredients mentioned as being in the original formula but not included in the list you provided (Argan Oil PEG-8 esters, shea butter oleyl esters, and Isocetyl stearate) are typically emollients or specialized esters. While these ingredients can contribute to the final texture, feel, spreadability, and specific skin benefits of the cream, they are generally not the primary emulsifying agents required to form the basic emulsion structure itself.

Therefore, you should be able to successfully form a cream emulsion using the ingredients and percentages listed in your provided formula. The resulting cream's texture and feel might differ from a formula that includes the additional emollients, but the fundamental cream structure should be achievable.
