Reviewing Natural Rose Lotion Formula: Scent, Brightening, and Preservation

Review of Your Natural Rose Lotion Formula

Hello! Your natural ingredient-focused rose lotion formula sounds very interesting. I have reviewed the ingredients and percentages you provided and would like to offer some additional guidance.

Adjusting Rose Water for Scent

The Rose Water (Rosa Damascena) you are using is a hydrosol obtained from rose distillation, rich in natural volatile oils that provide fragrance. The 5% you included is a good starting point.

• Recommendation: The ideal percentage of Rose Water for fragrance depends on personal preference and the concentration of the Rose Water itself. You can start with 5% as in your current formula. If you desire a stronger rose scent, you can increase the amount of Rose Water, reducing the plain water accordingly to maintain a total of 100% for your formula. Rose Water can be used up to 100% in cosmetic formulations, but you must consider its compatibility with other ingredients in the overall formula.

Adding Ingredients for Brightening

Regarding your question about adding an ingredient for skin brightening and whether Yeast Radiance™ is suitable:

• Recommendation: Yeast Radiance™ is a protein extract from a special yeast strain developed to help the skin appear brighter and more radiant (a Brightener), rather than making the skin look pale (a Whitener). Based on the information, Yeast Radiance™ can help improve skin radiance with continuous use and is gentle, unlike some direct whitening agents that can cause irritation.
• Recommended Usage: If you wish to add Yeast Radiance™ to your formula for brightening benefits, it is recommended to use it at a rate of 3% according to the usage guidelines. You can incorporate Yeast Radiance™ into the water phase of your formula. You would need to reduce the amount of plain water by 3% to keep the total formula percentage at 100%.

Additional Suggestions for Your Formula

Your formula includes a good selection of natural oils and extracts beneficial for skin hydration, nourishment, and antioxidant properties, such as Rose Hip Oil, Argan Oil, Shea Butter, Vitamin E, and Willow Bark Extract.

• Preservative: A crucial consideration for any water-based lotion formula is the inclusion of a preservative. This is essential to prevent the growth of microorganisms, which can spoil the product and make it unsafe to use. Since your formula contains 84.4% water and 5% Rose Water (totaling nearly 90% water phase), it is absolutely necessary to add a suitable preservative at the recommended usage rate.
• pH Level: Some ingredients, like Willow Bark Extract and Yeast Radiance™, are most effective and stable within a specific pH range (approximately 4.0-6.5). After preparing your lotion, you should check and adjust the final pH of the product to ensure these active ingredients function optimally and the formula remains stable.
• Viscolam AT 100P: The 1.5% of Viscolam AT 100P is effective as an emulsifier and thickener, helping to create the lotion texture and bind the water and oil phases. It is easy to use in both hot and cold processes, simplifying your formulation process.

In summary, your formula provides a good base for a natural lotion. Adding Yeast Radiance™ at 3% will enhance its brightening properties, and the amount of Rose Water can be adjusted based on your scent preference. However, please remember to include a preservative at the appropriate concentration for product safety and longevity.
