Reviewing Body Lotion Formula for Texture and Ingredient Issues
Question
I have developed a body lotion formula with the goal of achieving a light, non-sticky texture suitable for normal skin and nighttime use. I would like to know if this formula is suitable and if there are any potential issues.
The formula includes:
- Aloe Vera (Actives Extract 10:1) 5%
- Allantoin 0.4%
- Vitamin B5 (Panthenol)
- Mineral Water 76.6%
- Other ingredients
Specifically, I am concerned about:
- Whether the texture will be light and non-sticky as intended.
- If 0.4% Allantoin will fully dissolve in the water phase.
- If using 5% of the Aloe Vera extract is appropriate.
- Whether Vitamin B5 might contribute to stickiness.
- Is using Mineral Water acceptable?

Hello,
Based on the feedback you received and your goal of creating a light, non-sticky body lotion for normal skin to use at night, this formula appears generally suitable.
Here are the key points and potential adjustments based on the discussion:
- Overall Suitability: The ingredients you've chosen are compatible and should result in a relatively light texture, suitable for normal skin and nighttime use without feeling heavy or sticky, as you desired.
- Potential Adjustments/Checks:
- Aloe Vera (Actives Extract 10:1): It's recommended to check the supplier's suggested usage rate for this specific extract. While you proposed 5%, the feedback mentioned a typical range of 1-3%. Using within the recommended range is generally best practice.
- Allantoin: You should verify if 0.4% Allantoin fully dissolves in the water phase (76.6% Mineral Water). Allantoin has limited solubility, and you might need to adjust the percentage or use a different method to ensure it dissolves completely.
- Water Type: It's highly recommended to use cosmetic-grade purified or deionized water instead of mineral water for cosmetic formulations. This ensures purity and stability.
- Stickiness: While the formula is expected to be light, if you find it feels sticky after making it, Vitamin B5 (Panthenol) is often a contributor to tackiness at higher percentages. You could try reducing or removing Vitamin B5 if stickiness is an issue.
In summary, the formula is a good starting point for your goal. Pay attention to the points raised about ingredient solubility, usage rates, and water type during preparation. The texture should be light as intended.
Hope this helps!
