General Questions

Q: How do I request a sample or place an order for your products?
A: You can place an order for our cosmetic ingredient products by contacting one of our distributors. Please see our Worldwide distributor list. To place an order for a pharmaceutical product please contact your local drug wholesaler. If they do not carry the product, please contact Bob Rubinger by phone at (631)273-0900 or e-mail at evp@u-g.com. You can also contact Bob Rubinger for our industrial products as well. To request a sample contact one of our distributors or contact us directly depending on which product it is. Our general information email address is info@u-g.com.

Q: How can I obtain a data sheet, specifications, or an MSDS for one of your products?
A: You may obtain this information by doing one of the following:
1. Going to our website and choosing the product information option.
2. By contacting us and then we can mail, e-mail, or fax you the info.

Q: Are your products USP or NF grade?
A: No. Our products are mixtures and do not have USP or NF monograph classification.

Q: How can I obtain sample formularies for your products?
A: You can obtain sample formularies through our website by choosing the product information option.

Cosmetic Ingredients

Q: Do you test your cosmetic ingredient products on animals?
A: No! Our company policy is not to test or commission any testing of any of our cosmetic ingredient materials on animals.

Q: Are your Lubrajel(R) products animal derived? BSE (Bovine Spongiform Encephalopathy) free?
A: Our Lubrajel products are not animal derived. They are comprised of synthetic and/or vegetable material and are, therefore, BSE free.

Q: What are the benefits to using Lubrajel in my products?

A: There are many different benefits to using Lubrajel including superior moisturization of the skin, water soluble emolliency and rheology modification. Lubrajel may also be used as a general medical lubricant in a variety of applications.

Q: How safe are your Lubrajel products?
A: Lubrajel is characterized as having an excellent toxicological profile. It has an oral LD 50 greater than 5 grams per kilogram, it is not irritating to the skin, eyes, or mucous membrane tissue and is not a sensitizer.

Q: How should I clean Lubrajel off of my equipment?
A: Your Lubrajel equipment can be cleaned with either a sodium chloride or potassium chloride solution. Mix 1lb. of either sodium chloride or potassium chloride with 4 gallons of water. Clean as necessary. Rinse equipment thoroughly since the salts will lower the viscosity of our gel.

Q: How do I mix, pump, stir Lubrajel?

A: Lubrajel has pseudoplastic rheology. This means that under higher shear rates it has lower shear stress and pumps very easily. We recommend using diaphragm pumps to move Lubrajel. Low shear mixer design is also suggested, such as paddles. Homogenizers and other high shear mixers should be avoided.

Q: When do I add Lubrajel to my batch?
A: Lubrajel is usually added post-emulsion formation in creams and lotions. It is often added before the cool down of hot emulsions. It may also be used to stabilize cold manufactured emulsions.

Q: What is the compatibility of Lubrajel with other ingredients?

A: In most cases strong acids and bases, as well as oxidizing agents, should be avoided. Under certain conditions, hydrogen peroxide may be incorporated into Lubrajel at up to 10%. Please email or call for additional information on this specific application.

Lubrajel is generally compatible with most non-ionic compounds. The compatibility of materials with Lubrajel cannot absolutely be defined. There are some non-ionics that are not compatible. There are some cationic surfactants which exhibit compatibility such as acetamidopropyl trimonium chloride. Other materials that demonstrate compatibility with Lubrajel include ethanol, Polysorbate 80, and sodium cocoamphopropionates.

Q: Does Lubrajel Oil contain oil?
A: No. Our Lubrajel Oil does not contain oil and is completely water soluble. The word "oil" in the name was chosen as a descriptor for the oil-like viscosity of this product.

Pharmaceuticals

Q: Clorpactin is often substituted for modified Dakin's solution (its precursor). What is the equivalent concentration to full strength Dakin's solution? How does Clorpactin WCS-90 differ from modified Dakin's solution?
A: Full strength Dakin's solution is equivalent to a 0.4% Clorpactin WCS-90 solution (One 2 gram bottle of powder in 500 ml of water). The most important difference is the pH of the two solutions. Dakin's has a pH of about 9.5-10.0 whereas Clorpactin has a pH of 6.4-6.8. This results in two very important factors. The relative neutrality of Clorpactin makes it much less irritating to normal skin tissue and to open wounds. In addition, solutions of hypochlorous acid derivatives like both of these increase dramatically in germicidal activity as the pH is decreased from 10 to 6. This is true both for the concentration in ppm necessary to kill microorganisms as well as for the time required to achieve a kill.

Q: Clorpactin powder was left at room temperature for a week. Is it still okay to use?
A: For any time period at room temperature (for example, a week) subtract that same amount of time (a week) from that product's expiration date. At temperatures above 25 °C this drop in activity is more rapid and the exact time and temperature of storage will be needed to determine its expiration.

Q: How long can I store Clorpactin solution?
A: At room temperature in a capped container the solution remains within specification for about 3-5 days. At refrigerator temperature in a capped container 7-10 days. Containers and covers should be glass, polyethylene or polypropylene. It is very important that the containers be very clean and should also be stored in a dark place since exposure to organic matter and/or sunlight (UV) can promote rapid degradation of the solution. Containers and covers should not contain any metal.

Q: Can Clorpactin solution be made and stored in plastic?
A: The product can be mixed and stored in plastic containers commonly used in packaging.

Q: What is the strength (%) of Renacidin Irrigation in the 30mL bottle?
A: It is the standard 10% solution, which is the only strength indicated in the literature and in the package insert.
