A little bit of sun exposure is healthy for us. Our bodies need that to get its daily dose of Vitamin D. In fact, experts recommend an average of 20 minutes a day of sun exposure to optimize the health benefits of the sun.
However, if the body gets too much sun, or too much tanning, a lot of great damage to the skin may occur. In the long run, the skin gets weathered and lose its youthful look, dried out, wrinkled, or worst, one can get skin cancer.
Thankfully, scientists invent the Sunscreen to come to the rescue. A Sunscreen or Sunblock is a lotion, cream or ointment that we apply to the skin to absorb or reflect the sun’s ultraviolet (UV) radiation to protect us from the harmful effects of too much exposure to the sun.
Doctors and the FDA strictly recommend applying sunscreen with SPF 15 – 30 over the exposed parts of the body after 20 minutes of sun bathing or whenever it gets wet after swimming or sweating. This is where we see how relevant a bottle of sunscreen is. It is not just an accessory but an essential ‘amulet’ that we should carry around to protect us from the deadly effects sun.
Diving deeper, the sunscreen is actually formulated uniquely and has to go through complex processing. The manufacturing technique of sunscreens plays a vital role in optimizing the performance of permitted ingredients, as there are certain restrictions in the use of some UV filters.
Sunscreens are commonly in the form of sun milk, which is a liquid emulsion. An emulsion is a mixture of either oil-in-water or water-in-oil. Sunscreens can also come in the form of cream , oil, spray, or gel.
The ingredients for each type of sunscreen or suntan are almost the same, with a few difference in its formulation. The formulation for each determines the specific Sun Protection Factor (SPF) that is needed to be achieved.
Avobenzone or Parsol is an oil-soluble ingredient used in sunscreen products to absorb the full spectrum of UVA rays. FDA has determined this product as safe up to 3% concentration. Other synthetic ingredients for spectrum protection are the benzophenone and oxybenzone, which absorbs UV light.
Natural Minerals and Antioxidants
A popular natural mineral in sunscreens is Titanium dioxide, which scatters UV light instead of absorbing it. It has a whitening effect in the higher SPF ratings. Oxidation of oils is decreased by this natural mineral, thus preventing mixture degradation.
Antioxidants such as Sesame oil, Vitamins E and C, rice bran and others are used further inhibits oxidation.
Moisturizing and Soothing Minerals
Sunscreen formulation contain skin soothing and moisturizing additives such as aloe and chamomile. These coat the skin, forming a physical barrier that prevents the loss of water and produces a rejuvenating effect on the skin.
A complete ingredients dispersion together with obtaining the right UV filter and absorbers particle size are detrimental in producing an effective sunscreen lotion for UV protection.
The traditional sunscreen lotion/suntan cream-making process is summarized below:
Micronized Oxides are Completely Dispersed
Optimal SPF is obtained with the micronized oxides being completely dispersed by Ginhong Mixer
Yield of Ingredients in Maximized
Thickening agents are fully hydrated and active ingredients fully dispersed
Fast and convenient of mixing, emulsifying and homogenizing components as compared to the length of time it takes to get the job done by other conventional mixers.
Fast Inherent Reaction Rates
Intense and enhanced chemical reaction with high degree of concentrated input energy that produce superior dispersion than traditional mixing methods.
Efficient dispersion highly enhances color strength.
Ginhong Sunscreen Mixer is capable of attaining uniform and homogeneous emulsion, with good physical and chemical properties.
Increased Energy Savings
Heating may not be required In many cases heating is not required, reducing costs and risk of degradation of heat sensitive ingredients.
The overall mixing system forms a close loop, meaning it prevents unwanted air from entering into the system. With less to no air entering the system, cavitation or formation of bubbles in a liquid, which causes blade damage, is prevented.
Reduced Waste and Sanitary
The mixer is equipped with a Scraper made of a Teflon or a non-stick coating. This material is easy to clean, hard to be dissolved in all solvents and can withstand high temperatures. The Scraper gathers material wastes which can be collected without process interruption.
