Leading Manufacturer for Carbon Fiber Exhaust Tailpipe - Hydroxyethyl Urea – Cosroma Biotech Detail:
Hydroxyethyl Urea is an excellent moisturizer, which can provide the skin care products with effective moisturizing effect without sticky feel. In the formula, the dosage of siloxane can be reduced. Hydroxyethyl Urea can penetrate into the stratum corneum, increase skin moisture content, relieve dryness, fill fine lines, increase skin elasticity, and provide a pleasant feeling of use. Can be compatible with the most raw materials of cosmetics, has a wide range of PH.
Hydroxyethyl Urea is a new kind of moisturizing agent with outstanding advantages. Compared with the traditional moisturizer, Hydroxyethyl Urea have more remarkable moisturizing effect, smooth coating feeling, in the skin care products is not sticky, not greasy, moist and comfortable feeling, and non ion are part of the very broad applicability. And compared with expensive moisturizers, Hydroxyethyl Urea can achieve the same effect with lower formula costs. Give priority to with glycerin, propylene glycol, even in the basis of the formula, Hydroxyethyl Urea can also by reducing the dosage of the other components of the look of the cream (such as silicone oil), to achieve better moisturizing effect, more smooth coating, formula of the same or lower cost. Even in extreme conditions, under the condition of 6% relative humidity, Hydroxyethyl Urea can also pass and skin cutin layer to form liquid crystal phase, prevent cutin layer to the solid phase transformation, to achieve the purpose of make the skin soft.

Since Hydroxyethyl Urea has excellent moisturizing effect and skin feeling, and is safe for skin and eyes, it can be widely used in:
Skin care products, various creams and lotions.
Essence and various transparent products.
Sunscreen products: suntan products, suntan products and post-exposure products.
Hair removal, deodorant products.
Hair products: shampoo, conditioner, hair styling products, hair dye products, water, etc.
The moisture absorption was tested by dynamic steam adsorption.
Dynamic vapor adsorption tested at 100% active 36 degrees Celsius on relative humidity (RH) : from starting point to be balanced RH = 0% to 85% RH =, the balance of the tested sample to test its change under maximum RH results: Hydroxyethyl Urea absorb its own 82% of the water, and glycerin absorbed itself only 34% of the water samples (balance) under 36 degrees c and 85% relative humidity
Hydroxyethyl Urea can spread to the cuticle of the skin, increase the hydration of the skin, reduce the clinical dry record, increase the skin elasticity, and have a very moist skin feeling. Hydroxyethyl Urea has a superior moisturizing effect and a more comfortable skin tone with the same active substance, and the same results are obtained in the comparison of volunteers’ clinical trials.
1. The cuticle tester tests the moisturizing effect:
The Carbomer with 5% active substance Hydroxyethyl Urea and glycerin was applied to the dry skin test forearm. The humidity of 5min, 15min, 1h, 2h, 4h, 6h and 24h (23c, 32% relative humidity) was measured before and after using the instrument.
2. Determination of skin elasticity through the gas bearing electric dynamometer:
The Carbomer with 5% active substance Hydroxyethyl Urea and glycerin was applied to the dry skin test forearm. The skin elasticity (23 degrees c, 32% relative humidity) was measured before and after 5min, 15min, 1h, 2h, 8h and 24h.
3. Comparison with other moisturizers:
Hydroxyethyl Urea has a more prominent moisturizing effect than glycerol and other commonly used moisturizers. It also has a very good coating sensation, which is excellent for post-skin feeling. The glycerine gives the tester a sticky, thick, and negative effect on the residue. Compared with other tested moisturizers (such as PAC sodium, sorbitol, urea), Hydroxyethyl Urea is more prominent in many ways. Especially the wettability Hydroxyethyl Urea has higher, more coating, low consistency and little residual skin feeling, and don’t shine, not sticky, on the skin absorption rate, half is more faster than glycerol.
Hydroxyethyl Urea is stable in a wide range of PH and temperature and can be easily added at any temperature.
Stored in a cool and dry place, keep sealed and avoid light preservation.
In 50% of the high concentration storage time for more than half a year, there will be a slight decomposition, with a light ammonia flavor and a higher PH, which can be directly adjusted to the appropriate PH in the formulation without affecting the use. However, under the use of the formula, the overall concentration is low, and there will be no decomposition, and no free ammonia will appear.
The experiment with CO2 change (OECD 301B) shows that Hydroxyethyl Urea is easily degraded.
The field of product application.
