- The easiest way to treat dry skin is to spread on some skin cream.
- It rejuvenates the skin cells and acts as a protective barrier.
- This is particularly important in the winter
- when cold outdoor air and indoor heating suck the moisture out of your skin.
- If you have dry skin, it's wise to keep a good supply of skin cream on hand.
- It's not just dry air that makes skin flaky and itchy.
- Cancer treatments can also dry out the skin,
- along with other medical conditions like diabetes.
- The first ingredient is stearic acid.
- It's a wax derived from palm tree oil.
- The next ingredient is refined lanolin.
- It's blended with isopropyl myristate,
- a natural oil that helps soften the stearic acid.
- These ingredients make up what's called the oil-soluble phase of the recipe.
- Workers heat the stearic acid until it liquefies.
- Then add the blend of lanolin and isopropyl myristate and keep heating.
- While the oil phase is heating, they prepare the water-soluble phase of the recipe.
- The first ingredient is glycerin, derived from a vegetable source such as corn.
- They heat and mix it, then add purified water.
- They continue heating the mixture to just below the boiling point.
- Add a floral fragrance.
- Then pump the oil phase into the bottom of the tank.
- It blends in with the water phase while naturally rising to the top.
- They gradually lower the temperature.
- This makes the mixture creamy and bright white.
- After an hour of mixing, the skin cream is ready.
- They pump it out of the mixing tank to supply tanks that feed the filling line.
- This company packages its skin cream in jars for body cream and tubes for hand cream.
- Workers unpack boxes of plastic jars
- and line them up on a conveyor belt that feeds the labeling machine.
- Each jar passes a photo eye sensor.
- This sensor triggers the machine to spin the jar at the same speed as the adhesive label coming off the roll.
- Workers place the labeled jars onto a turntable that feeds the filling machine.
- Two single-file lanes each lead to three nozzles.
- The machine fills up to 125 jars per minute.
- Depositing 12 ounces of skin cream into each jar.
- The two lanes of filled jars merge as they approach the capping machine.
- The caps come down a chute to the machine's carousel.
- A device called a timing screw correctly positions each jar to receive a lid.
- The lower part of the machine holds the jar steady as an arm secures the lid in place.
- The next station on the line applies an adhesive label onto the cap.
- The jars of body cream are ready for sale.
- This factory also packages hand cream in a tube
- that you can keep in your purse or pocket.
- A mechanical arm places the tubes on a turntable cap-side down.
- The bottom of each tube is open and ready for filling.
- A nozzle squirts two ounces of skin cream into the tube.
- Then the machine heats the open end to soften the plastic.
- clamps it shut, then cools the plastic to a solid state,
- When you rub the cream on your skin,
- the key ingredients glycerin and lanolin pack a one-two punch.
- Glycerin is hygroscopic, meaning it draws water from the air to the skin.
- Lanolin smooths the skin, forming a protective film to lock in the moisture.
