Adjusting Lotion Formula for Light, Fast-Absorbing Texture

Asked by: patcharinexo3079 On: November 02, 2020 Product Type: Cosmetics

Question

I have a lotion formula with the following ingredients and percentages: Stearic acid 3%, Cetyl Alcohol 3%, Glycerin 5%, Disodium EDTA 0.05%, Preservative 1%, Cordyceps powder 2%, Water 85.95%. How can I adjust this formula to achieve a lotion texture that is not sticky and absorbs quickly into the skin? Are there any specific ingredients you would recommend?

Answer

Formula Adjustment for Light, Fast-Absorbing Lotion

Your current formula includes Stearic Acid and Cetyl Alcohol, which act as thickeners and emollients, and Glycerin as a humectant. These ingredients contribute to the body and moisturizing feel of the lotion.

To achieve a less greasy, faster-absorbing lotion texture, you can consider the following adjustments:

  1. Choose a suitable Emulsifier: The type of emulsifier significantly impacts the final texture. Consider using a "light" emulsifier designed to create non-greasy formulas. Products like Light Lotion Maker are specifically formulated to provide a light feel and can help achieve the texture you desire.

  2. Incorporate Light Emollients: Adding emollients known for their fast absorption and non-greasy feel can greatly improve the texture. Consider adding ingredients such as LipidSoft B or Dimethicone (Ultra Light/1.5, Low-Odor). These can replace a portion of the oil phase or fatty alcohols (Stearic Acid, Cetyl Alcohol) in your formula to reduce the heavy feel while maintaining spreadability and skin conditioning.

  3. Review Thickener Levels: While Stearic Acid and Cetyl Alcohol are useful, their combined level (6%) might be contributing to the richness. Once you incorporate a new emulsifier and light emollients, you might find you can slightly reduce the percentage of Stearic Acid and/or Cetyl Alcohol if the texture is still heavier than desired. However, start by adjusting the emulsifier and adding light emollients first.

  4. Cordyceps Powder Dispersion: Ensure the Cordyceps powder is very finely milled and properly dispersed in the formula. Undissolved powders can sometimes affect the smoothness and absorption feel.

Suggested Approach:

  • Replace your current emulsifying system with Light Lotion Maker at its recommended usage rate (typically 2-4% depending on oil phase). You may need to experiment with the percentage based on your total oil phase (Stearic Acid, Cetyl Alcohol, plus any other oils/butters you might add).
  • Add LipidSoft B (e.g., 3-5%) or Dimethicone (Ultra Light/1.5, Low-Odor) (e.g., 1-3%) to the oil phase to improve the light feel and absorption.
  • Keep Glycerin at 5% initially. Adjust later if needed.
  • Maintain Disodium EDTA and preservative levels.
  • Ensure Cordyceps powder is well dispersed.

By selecting a lighter emulsifier and incorporating fast-absorbing emollients, you should be able to significantly improve the texture of your lotion to be less sticky and absorb more quickly into the skin.
