Urea is extracted from proteins. ultra high purity Moisturizes the skin very well. Helps replace the urea beneath the skin. which is responsible for balancing moisture under the skin Suitable for dry, dehydrated skin. It also has the effect of helping to exfoliate skin cells. (keratolytic) if the amount is more than 5%

 

It is recommended to use in conjunction with Sodium PCA and Sodium Lactate For maximum moisturizing efficiency This is because all three substances are important parts of the Natural Moisturizing Factor (NMF), which occurs naturally under the perfect skin.

 

because it is a moisture retention agent. The powder is characterized by very high moisture attraction. Must be kept in a dry place with a tightly closed lid.

 

Instructions for use of Urea in recipes:

1. Because Urea has long-term dissociation characteristics. And dissociate more quickly in temperatures above 35 degrees. When dissociated, the pH of the formula becomes more alkaline (pH increases over time), which, without control or stabilization, can lead to a high pH. Can reach level 11 when left in a hot place. For more than 3 months, stabilization of Urea is necessary. For products that require shelf-life for more than 3 months and cannot be stored at temperatures below 30 degrees.

 

2. Techniques to Stabilize Urea to Use Gluconolactone in approximately 15% of Urea, for example, if using 10% Urea in the formula, it should be used Gluconolactone at 1.5% to help control the pH of the formula by adjusting the pH appropriately to a range of 4-5.5 (if there are other acids in the formula, that help adjust the pH to be appropriate It's not necessary. Gluconolactone add more)

 

3. Urea will make the formula smell. which can reduce odor and stabilize by using Triacetin Help stabilize Urea in the formula by using it at a rate of approximately 1 (Triacetin) :10 (Urea). Triacetin will help control the pH to not increase, making Urea stable for longer.

 

Use: for skin care products Moisturizing dry skin.

Mixing method: Mixed in water (water-phase) can withstand heat. 60 degrees for a short time, must stabilize as well Gluconolactone Please see details above

Usage rate: 3-20% for moisturizing (use according to the desired performance If very dry skin can use 5%) 10-20% for exfoliation and moisturizing.

Product characteristics: White to light yellow powder, crystalline powder, pH approx. 7.2, slight odor.

Solubility: can dissolve in water

Storage: For long term storage Store at room temperature Avoid exposure to sunlight, moisture, heat. Seal the lid tightly. Absolutely avoid moisture.
