Gentle Facial Cleanser Formulation Questions

Regarding the gentle facial cleanser formula you provided, here are the answers to your questions:

Adding Light Cream Maker

Yes, you can add Light Cream Maker at 1% to turn the formula into a cream. Light Cream Maker acts as both an emulsifier and a thickener that works without heat. Since your formula is primarily water-based, you can add the Light Cream Maker to the water phase and mix well before combining it with the mixture of Lauryl Glucoside, Propylene Glycol, and Glycerin. Alternatively, you can add it to the final mixture and stir gently until the desired cream consistency is achieved. Avoid vigorous stirring to prevent excessive foaming.

Replacing Glycerin with Oils

Replacing Glycerin with oils like Fractionated Coconut Oil or Sesame Oil is not recommended in this formula. Glycerin is a water-soluble humectant and solvent, helping to draw moisture to the skin and dissolve ingredients in the water phase. Oils, on the other hand, are emollients that are not water-soluble. Directly substituting Glycerin with oil would require a different type of formulation (an emulsion) and a suitable emulsifier capable of incorporating a significant amount of oil. The original formula is not designed to incorporate a large oil phase, and adding 30% oil would likely not mix properly and would change the texture and function of the cleanser significantly, potentially making it greasy.

Need for Preservative

Yes, it is essential to add a preservative to this formula. Any cosmetic product containing water is susceptible to microbial growth (bacteria, mold, and yeast), which can spoil the product and pose a health risk. Ingredients like Lauryl Glucoside, Propylene Glycol, and Glycerin are not sufficient on their own to protect the product from contamination. Adding a suitable cosmetic preservative will ensure the safety and extend the shelf life of your gentle facial cleanser.
