Zinc Stearate for Skin
Zinc stearate isn’t exactly one of those ingredients that rolls off the tongue. And it probably doesn’t ring a bell when you hear the name. But don’t let that fool you—this cosmetics ingredient is everywhere.Get more news about Zinc Stearate,you can vist our website!
Zinc stearate is a zinc salt made from a fatty acid called stearic acid,” explains board-certified dermatologist Blair Murphy-Rose, MD, FAAD. “It has been used as a binding agent in powdered cosmetics (like powders, blushes, and eyeshadows), as a thickening agent, and as a lubricant.”
We asked Murphy-Rose and board-certified dermatologist Whitney Bowe, MD, to explain why this ubiquitous ingredient is probably in some of your favorite products, plus exactly what it does.
What Is Zinc Stearate?
Zinc stearate is "basically the zinc salt of stearic acid, which is a long-chain fatty acid,” says Bowe. “Stearic acid is a waxy substance that can act as an emollient and an emulsifier, so it can make skin feel softer and can also help ingredients in a formulation mix together nicely so that the experience of applying that product is more elegant," she continues. "Zinc stearate, the zinc salt of stearic acid, can also help with hydration, and improve the texture of a cosmetic product, giving it more slip.”
Though the ingredient is common enough, it’s typically used as part of the equation in a formula—it isn’t the star of the ingredients list. “Overall, it’s a very safe ingredient, although I wouldn’t call it a superstar active ingredient that drives results,” Bowe says. “It’s safe to include in formulations to enhance the overall experience and help with creating a homogenous, elegant formulation. However, I wouldn’t look for this ingredient to deliver any dramatic improvements in the skin.”
Side Effects of Zinc Stearate
Although it is generally considered a safe ingredient, those with sensitive skin may want to tread carefully. “It has been questioned as an occupational hazard [specifically] as a respiratory hazard,” cautions Murphy-Rose.1 “Used in cosmetics, it has a low but possible risk of toxicity. It is also possible to be an environmental toxin. It may also be a skin irritant.”
How to Use It
Zinc stearate isn’t an ingredient you can find on the shelves solo; rather, it’s used in products that have been formulated with it. “I have most often seen it as an ingredient in cosmetic powders,” Murphy-Rose says. “It helps to prevent ingredients in powdered cosmetics from caking and it helps them to bind to the skin.”
If your skin tolerates zinc stearate well, it can be used daily, according to Murphy-Rose. However, she warns that because it is a water-repellant, it may not work well with water-based products.
This pick is Murphy-Rose's “all-time favorite powder bronzer.” Thanks to its blending powers, the matte bronzing powder will leave your skin looking naturally sun kissed. Whether you want a touch of color or a deep tan, the buildable bronzer will get you there.
“A nice mineral-based finishing powder,” according to Murphy-Rose, this completely sheer setting powder blurs pores and minimizes fine lines and wrinkles while helping your makeup go the distance. It doesn’t produce any flashback and feels weightless on the skin.
This iconic makeup artist's fave is "long-lasting and sticks well to the skin for an extended duration, and the colors are beautiful,” Murphy-Rose says. Available in a range of shades and finishes—shimmer, matte, or satin—this pressed powder blush is delightfully blendable and buildable. The micronized powder pigments feel super silky on the skin.
Inhalable hydrogel protects lungs from SARS-CoV-2
Mutations in SARS-CoV-2, the virus that causes COVID-19, continue to produce new virus variants. Some of these mutations may confer resistance to the immunity induced by vaccines or prior SARS-CoV-2 infections. Thus, there is a need for strategies that could prevent infection by a range of SARS-CoV-2 variants.Get more news about factory direct sale medical hydrogel manufacturers,you can vist our website!
Physical barriers, such as the mucus lining of the airways, provide the first line of defense against infections. A research team led by Dr. Ke Cheng at North Carolina State University set out to develop a way to reinforce this mucus barrier. They described their method, which they dubbed spherical hydrogel inhalation for enhanced lung defense, or SHIELD, in Nature Materials on February 9, 2023.
SHIELD consists of an inhalable powder of fine particles, less than 5 μm across, made from an absorbent polymer. Upon contact with moisture, the particles absorb water, which causes them to swell. Within 10 minutes, they link with each other to form a hydrogel. Electron microscope imaging showed that mucus with SHIELD added formed a denser and stiffer gel, with smaller pores, than mucus alone. Virus-sized particles didn’t cross through this denser gel as easily as through ordinary mucus.
The team tested whether SHIELD could protect against virus infection in mice. They administered SHIELD to the mice via a dry powder inhaler and found that SHIELD coated the surfaces of the lower airway. They then exposed the mice to harmless viruses with spike proteins from different SARS-CoV-2 variants. SHIELD reduced the infection rate by 72-75% four hours after SHIELD administration. This declined to 15-18% after 24 hours as the gel was cleared from the mice.
Next, the researchers tested SHIELD in monkeys. The monkeys received a single dose of SHIELD 8 hours before exposure to either the original SARS-CoV-2 strain or the Delta variant. SHIELD-treated monkeys had 50- to 300-fold less virus than untreated animals. Lungs from treated monkeys also had reduced inflammation, viral pneumonia, and signs of damage.
SHIELD was created from food-grade materials, was not toxic to cells in culture, and did not affect normal lung function in mice after two weeks of daily dosing. It could be easily administered daily using a low-cost inhaler.
How interactive whiteboards took over
From blackboards in the 1800s to whiteboards in the 1960s, technological advancements enabled the creation of interactive whiteboards in the 1990s.Get more news about Hot Sale Smart Interactive Whiteboard,you can vist our website!
Xerox PARC invented the first interactive whiteboard in 1990, allowing people to directly connect their computers to a board while maintaining regular whiteboard capabilities. In 1991 the leading interactive whiteboard company, SMART Technologies, released its first product, the SMART Board. Initially, these boards were geared towards offices and small meetings. However, in the late 90s, interactive whiteboard companies adjusted the target consumers towards schools.
Thousands of schools across the world, including Carlmont, thought this new device would revolutionize education.
On paper, interactive whiteboards seemed like the real deal. Connecting a computer straight to the front of the classroom makes lesson planning much quicker and simpler. Teachers can immediately display notes on PowerPoint presentations without having to write them out during a lecture. But in reality, how would they perform?
“My first impression of the SMART Board was being terrified and confused, as I usually am over new technology, but as I gradually learned how to use it, I felt more comfortable with it. Pre-pandemic, I was using it every day in class, all day long,” said David Gomez, a history teacher at Carlmont.
SMART Boards came with steep learning curves for many teachers. Once they overcame this, interactive whiteboards began to show their worth. Along with simpler lesson planning, a study in 2009 showed an increase in student engagement, suggesting that it was easier for students to participate and made class more enjoyable.
“The pros of a SMART Board are the ability to access information and materials from online sources and display them in front of the class; particularly things which previously had to be photocopied and distributed,” Gomez said. “Students use it all the time for presentations and projects as well.”
In addition, interactive whiteboards help many students grasp concepts much quicker through increased engagement and visual learning. According to the International Institute for Science, Technology, and Education (IISTE), increased engagement stimulates thinking and leads to an increased personal understanding of concepts. Furthermore, according to the Social Science Research Network (SSRN), 65% of the population are visual learners, and SMART Boards can display high-resolution photos and graphics.
“I think SMART Boards are really helpful because it helps our teachers stay organized, which helps us learn better because we can clearly see and understand what they are teaching us,” said Saya Deshpande, a junior.
However, there are two significant drawbacks to SMART Boards. The first one is the price. Interactive whiteboards do not come cheap; they could cost anywhere from $700 to north of $3000. Installation coupled with maintenance could easily set back a school tens of thousands of dollars. The second drawback is the actual functionality of the boards. Interactive whiteboards quickly become outdated, but replacement is not an option because of the cost. Many of Carlmont’s SMART Boards are now over a decade old, which causes them to become defective, and writing on them becomes inconvenient. They often lag and are inaccurate, so teachers tend to write on adjacent whiteboards and only use the SMART Board as a projector.

New generation of EagleBurgmann pump seals
These can be used to seal, among other things, chemical pumps, water and waste water pumps, circulating pumps and submersible motor pumps in numerous industrial sectors. The eMG1 is 100% compatible with the well-known MG1 standard seal. EagleBurgmann says it has been innovated in detail and functionally expanded. A vastly reduced outer diameter of the bellows support now allows direct support by a retaining ring or with the use of much smaller spacer rings. The optimized bellows shape improves the automatic alignment of the bellows on the shaft and minimizes stick-slip effects.Get more news about Submersible Pump Seals,you can vist our website!
EagleBurgmann says the profiled PEEK-PTFE disk ensures consistent centering across the entire pressure operating range, exhibits good sliding properties and safeguards the automatic alignment of the elastomer bellows in operation through continuous self-cleaning. The eMG is identical in construction with the eMG1, but has a 20% shorter installation length. This provides manufacturers with new opportunities in pump construction: e.g., a more compact design due to shorter shafts with the associated material savings and increased efficiency.
EagleBurgmann says the rotating unit is space-saving. The computed pre-modelled bellows design and the spring assembly have no excess lengths and the outer diameter of the bellows support was reduced to a minimum.
First Biodegradable Fabrics for Workwear Coming to Techtextil 2022
Global workwear fabric manufacturer, Carrington Textiles, has announced a busy agenda for the event which includes the promotion of a new sustainable technology for textiles, a commercial video, as well as giving away free passes to visit their stand in Frankfurt.Get more news about workwear fabric factories,you can vist our website!
Adlington, United Kingdom: Being the first textile manufacturer to use biodegradable technology to produce workwear fabrics, Carrington Textiles has announced their focus on the promotion of Orca and Hawksbill, as well as on their latest flame retardant addition, Flamestat 250, at Techtextil 2022.
Recently launched during their ‘Weaving Sustainability into our Fabrics’ campaign, where the company released their newest fabrics Constance 210, Balaton 255, Kielder 185, Delamere (210 & 245), and Rivington (205 & 220), Carrington Textiles’ Orca and Hawksbill stand out for their addition of the new CiCLO fibre.
The CiCLO technology is a sustainable textiles ingredient in the form of an additive that is combined with polyester at the very beginning of the fibre making process. When CiCLO polyester ends up in the environment either through washing or end of life of the garment, it behaves like natural fibres, in turn reducing microplastic pollution and textile accumulation.
Hawksbill’s composition includes 65% CiCLO polyester and 35% organic cotton. While Orca incorporates 26% recycled CiCLO polyester, 29% virgin CiCLO polyester and 35% Better Cotton. Hawksbill and Orca are the sustainable alternative to the company’s bestselling fabric, Tomboy.
These two fabrics are made following Carrington Textiles’ usual rigorous quality standards, so they not only offer the best performance and durability to the end user, but also greatly reduce their impact on the environment when the life of the garment comes to an end.
Carrington Textiles’ Managing Director, Neil Davey, says: “It’s great to be able to attend exhibitions once again. We have invested a great deal of resources into R&D to bring these sustainable fabrics to market and have already had excellent feedback from customers and partners. We are delighted to be showing them face to face to customers and all those interested at Techtextil”.
Hobby Servo Tutorial
Servo motors are an easy way to add motion to your electronics projects. Originally used in remote-controlled cars and airplanes, they now crop up in all sorts of other applications. They're useful because you can precisely control the positioning of these motors. Instruct them where to point, and they'll do it for you.Get more news about Data Servo Connector,you can vist our website!
An ordinary DC motor has two hookup wires and simply turns continuously when power is applied. If you want it to spin in the opposite direction, you'll need to reverse the power. And if you want to know how far it has turned, you'll need to devise a way to measure that.
In contrast, you instruct a servomotor where to turn using carefully-timed pulses. The servo has three wires: power, ground, plus a third wire to carry the command pulses.
Servo Motor Background
In the most generic sense, a “servomechanism” (servo for short) is a device that uses feedback to achieve the desired result. Feedback control is used in many different disciplines, including speed, position, and temperature.
In the context we are discussing here, we are talking about hobby or radio-control servo motors. These are small motors primarily used for steering radio-controlled vehicles. Because the position is easily controllable, they are also useful for robotics and animatronics. However, they shouldn’t be confused with other types of servo motors, such as the large ones used in industrial machinery.
RC servos are reasonably standardized - they are all a similar shape, with mounting flanges at each end, available in graduated sizes, from "ultra-nano" to "giant". Servos often come with multiple attachments, such as wheels or levers, known as “horns”, than can be attached to the shaft, to fit the device they are operating.
Electrical Connection
Most hobby servos use a standard type of 3-pin plug, with the same control signaling, which makes RC servos reasonably interchangeable.
The connector is a female, 3-pin, 0.1" pitch header. One thing that can be confusing is that the wiring color code isn't always consistent -- there are several color codes at play. The good news is that the pins are usually in the same order, just that the colors are different.
Control signal
The third pin of the servo connector carries the control signal, used to tell the motor where to go. This control signal is a specific type of pulse train. The pulses occur at a 20 mSec (50 Hz) interval, and vary between 1 and 2 mSec in width. The Pulse Width Modulation hardware available on a microcontroller is a great way to generate servo control signals.
Common servos rotate over a range of 90° as the pulses vary between 1 and 2 mSec -- they should be at the center of their mechanical range when the pulse is 1.5 mSec.
