Hi, my name is norfarahani binti ahmad shukri and you can call me hani. Im unofficially 20 years old. Im from pahang and also pahang matriculation college's student.

I would like to share about the relation between lip balm and chemistry. So actually chemistry plays a crucial role in the formulation of lip balm. Lip balm is a skincare product designed to moisturize and protect the lips. The ingredients in lip balm, such as wax, oils, emollients, and flavorings, are carefully selected and blended based on their chemical properties.

Additionally, the chemistry of lip balm includes considerations of pH levels, stability, and compatibility of ingredients to create a product that is effective, safe, and pleasant to use. Chemists and cosmetic scientists work to ensure that lip balm is formulated to meet these criteria.

Hi my name is Nur Alia Syafiqah but you can call me Alia. I am officially 19 years old.I'm from Johor Bahru,Johor. I'm student from Johore Matriculation College(JOMACO).Here i'll share with you about my Chemistry Wefie partner; phone cover.

So, this phone cover is made of silicone.Whenever you think of silicone, you probably think of synthetic rubber, which is partially true. Silicone, also known as polysiloxanes, is polymer group of synthetic compounds made up of repeating units of siloxane.Those repeating units are actually a chain of alternating silicon and oxygen atoms, typically joined with carbon, hydrogen, and sometimes other elements.One thing i love about silicone is it such a flexible material that can absorb shock unlike others material and environment friendly.

To sum up, learning chemistry is fun and can also be related to the environment.

Hi everyone. I'm Preethi . I'm 19 years old. Moreover, I'm from Melaka (Ayer Keroh). Lately I have done with my matriculation phase at kmj( Kolej Matrikulasi Johor).

Probably now you are curious about what am I holding in my hand.Okey let me explain. It's a lip balm. Lip balm is a wax-like substance applied typically to the lips to moisturize and relieve chapped or dry lips, angular cheilitis, stomatitis, or cold sores.On the other hand, lip balm often contains beeswax or carnauba wax, camphor, cetyl alcohol, lanolin, paraffin, and petrolatum, among other ingredients. Some varieties contain dyes, flavor, fragrance, phenol and salicylic acid.

That's all from me. Thank you for spending time to read this.

So now I want to talk a little bit about my partner which is this beautiful black chair. So this chair is made of two material which is metal and plastic or more specific is thermoplastic polypropylene

There are reasons on why this chair are made of thermoplastic polypropylene. This is because it will be easy to carry this chair to anywhere you want since it is very light. Next, it is more easier to mold it into any shape you like

Other than that, this chair is made of metal so that it is strong and it is not easy to break. So we can use it for a long time.

Eventhough it is light and strong make sure you guys use it wisely. Which is use it to sit down but don’t use it to throw to your partner when you see your partner with someone else.

That’s all from me, thank you.

2023-10-09 09:00:10 UTC

Assalammualaikum, my name is Nazim Basir bin Nawi. I'm from Sibu, Sarawak and I used to study in Kolej Matrikulasi Labuan. My matric's number is AW230110. The item that I'm holding in this picture is paracetamol or widely known as Panadol.
Paracetamol's chemical name is N-acetyl-p-aminophenol, and its molecular formula is C8H9NO2. It has a specific chemical structure, which is essential for its pharmacological effects. Chemists play a crucial role in the development and synthesis of paracetamol. Understanding the chemical properties and reactions of its components is vital in producing safe and effective medications. Chemistry helps explain how paracetamol is absorbed, distributed, metabolized, and excreted by the body. This knowledge is essential for determining dosage and usage guidelines. Chemists are involved in quality control processes to ensure that paracetamol products meet pharmaceutical standards. This includes analyzing purity, potency, and the absence of contaminants.

In summary, the development, formulation, mechanism of action, and quality control of paracetamol all have strong ties to chemistry. This drug's chemistry is fundamental to its efficacy, safety, and availability as an over-the-counter medication.

Assalamualaikum and good evening. My name is Muhammad Zul Irfan Bin Hairulnisam and I am 20 years old.I lived at Pasir Gudang which is located in Johor. You can call me "Zul". Before this I studied at Johor Matriculation College (KMJ).

Today, I want to share my partner which is ceramic tiles. Traditionally, tiles have been made of glazed or unglazed clay, but modern tiles are also made of plastic, glass, asphalt or asbestos cement.

To make a story, ceramic tiles are a mixture of clay and other natural materials, such as sand, quartz and water. They are mainly used in the home, bathroom walls and kitchen floor surfaces. It is easy to install, clean, maintain and is available at a reasonable price.

Ceramics show good strength and can withstand high temperatures and acidic materials but are brittle, weak in tension and shear. In conclusion, this partner of mine has shown how strong he is even though he is always stepped on, but still as strong as the relationship between the two of us. Thank you.

Have anyone ever wondered about chemical in toothpaste that keep our teeth healthy??
Okay I will explain to you , normally in toothpaste in chemistry is interesting mix of ingredients to maintain our oral hygiene.
One of main ingredient I will tell you is fluoride primary function of this ingredient are to strengthening tooth enamel and preventing decay of tooth. Fluoride property is base or alkaline. When we applied toothpaste consist of flourides it help our teeth to protect from bacteria that produce acid that can erode outer layer of teeth called enamel due to property off flourides its can neutralize back teeth and inhibit bacteria or cavity to growth. Okay that all from me thanks.

My wefie partner is handwash.As we know, usually we wash our hand using handwash before and after we are having a meal.

Now,let me tell you about the ingredients that contain in this handwash.It's contain water,sodium laureth sulfate,glycerin,fragrance,sodium chloride,methylchloroisothiazolinone,methylisothiazolinone and benzophenone.Sodium chloride is used to create the desired texture of handwash, hence creating soapy molecules adhere to one another. This creates an insoluble mass. It is a soft, white crystalline salt with the chemical formula "NaCl". The most common form of Sodium Chloride commonly used in commercial handwash is the 32.5% Sodium Chloride solution (aka Glycerinate).It is also very gentle on the skin and leaving it feeling soft and clean.The scent is produced from jasmine flower extract.So,this makes it smell very luxurious.Last but not least, methylchloroisothiazolinone inhibit bacterial growth in cosmetic product on their own.

To sum up, it's very important for us to wash our hand, so that we can prevent bacterial infection cases like respiratory and diarrheal infections as hand hygiene is the most important practice in healthcare settings.

Assalamualaikum, hello! My name is Allys Syarmiela, also known as elsa as that is what my housemates call me. I was born in Pahang. I used to be a student at Pahang Matriculation College. The chemistry-related thing for today is lotion.

Starting off with what is a lotion?Lotion acts as a moisturiser, which prevents the skin from drying out due to the humid or warm weather. The main components in a lotion are petroleum and water. What petroleum does is trap the moisture on the skin; water, on the other hand, is meant to hydrate and moisturise the skin. Hence, these two ingredients do not combine together, as petroleum is oil-based. In order to fix this, surfactant is added which will attract both water and oil to produce a mixture. Surfactants are amphiphilic molecules that have hydrophobic and hydrophilic parts. Because of their amphiphilic nature, surfactants absorb the oil-water interface. At the interface, surfactants align themselves so that the hydrophobic part is in the oil and the hydrophilic part is in the water.

On final note, use lotion to achieve that plump skin texture which is as you can see mine’s not plump.

Thank you!

Here is my sharing about plastic container.As we know, plastic container have high demand in industry and in our daily life.This food container is one of the things that we usually use as the benefits are affordable price, reusable and made of safe plastics.

The food plastic container that shown at the picture is made of
Polypropylene is an ideal food-safe plastic for production processes that require high heat. It can be found in products ranging from prescription bottles to garden tools and automotive products. While fairly stiff, polypropylene is not as brittle as other common food packaging plastics. Food items that utilize polypropylene for packaging include yogurt, cream cheese/sour cream containers, ready-to-eat meals and VSP containers. Polypropylene has gained popularity for microwavable containers thanks to its high melting point.

The benefits of it are durable,easy to handle,non staining, reusable ,has lightweight which helps to preserve the quality and nutritional value of the food.

That's all from me,
thank youu.

A lipstick composition comprising by weight from 8% to 20% of waxes, 30% to 80% of oils, 3% to 30% of colorants, 8% to 20% of cetearyl isononanoate, 1% to 10% of a sesquistearate and 2% to 20% of isopropyl hydroxystearate. But do you know what is made the lipstick have vibrant red colour? Well, it is

RICINOLEIC ACID

Lipstick colour originates from a range of different pigments and dyes. Carmine red is a commonly used pigment derived from scale insects. Eosin, also known as D&C Red No. 22, is a dye which reacts with the amino groups in the proteins of the skin to produce a deep red colour.

Hi assalamualaikum everyone. My name is Nurul Nazahah binti Mohammad Najib and you can feel free to call me 'nazahah' or 'naz/nas'. I'm from Tawau, Sabah and before I got accepted into UTHM, i was a student in Labuan Matriculation College (LMC).

After a deep thinking, I chose SOAP as my subject or partner in today's topic. As we know, soap is one of our necessary cleaning products. To be more precise, SOAP is a salt of a fatty acid used in a variety of cleansing and lubricating products. In a domestic setting and also in industrial settings. The chemical structure of sodium laureth sulfate, a typical ingredient found in liquid soaps.

It is uncertain as to who was the first to invent soap. The earliest recorded evidence of the production of soap-like materials dates back to around 2800 BC in ancient Babylon.

So based on Google (Wikipedia), soap has existed since the old days and keeps on revolving till today with various type of smells.

Vanakkam and hello everyone!!! Hope you all are doing fantastic. I'm Saravanakumaran A/L Manickam and I'm 20 years old. I pursued my STPM in science and was able to complete it successfully. Oh yeah and I'm from Kuala Lumpur aka KL.

Wondering what I'm having with me? That's right it's an adhesive (glue). Adhesive, also known as glue, cement, mucilage, or paste, is any non-metallic substance applied to one or both surfaces of two separate items that bind them together and resists their separation.

Since we're diving deep into the ocean of chemistry, let me introduce the chemical name of glue which is Polyvinyl acetate. An aliphatic rubbery synthetic polymer with the formula (C4H6O2)n, it belongs to the polyvinyl ester family, with the general formula -[RCOOCHCH2]−.

Let's peep a little at the preparation of our beloved glue. Polyvinyl acetate is prepared by the polymerization of vinyl acetate monomer (free-radical vinyl polymerization of the monomer vinyl acetate).

Hence, I hope y'all have learned something new, let's keep sharing ideas and excel ourselves folks. That's all from me. Adiós!
