Exposure to the sun can damage the skin permanently. Use of Sunscreen Formulation can give you protection against any damage. The harm might be short-term or long-term depending on the type of skin and the period of exposure. The short-term damage manifests as erythema or redness of the skin which people call sunburn. Melanocytes get activated leading to increased production of melanin. This darkens the skin causing a tan to appear.
Making the Sunscreen Formulation The Sunscreen Formulation involves the mixing of an oil phase and a water phase to form an emulsion. Absorbers and UV filters get mixed in as dry powder. The water phase contains emulsifiers and stabilizers. Powder ingredients such as stearic acid and cetyl alcohol get dispersed into the oil phase. This can give you enough long-term protection as well as a short-term one. Damage caused by UV rays When we talk of long-term damage we refer to skin elasticity lost permanently. It might lead to the development of skin cancer. The actual damage depends on how long one remains exposed and the intensity of the sunlight at that time. Other factors that determine the level of damage are age, gender, color, and immune status. So, one has to consider these factors while making the sunscreen product formulation. Protection Using Sunscreens The use of material to get protection from the harmful effects of the sun’s rays has been around for a long time. In the sun’s rays, we have gamma rays, cosmic rays, radio waves, microwaves, UV rays, and X-rays. The main focus of the sunscreen product formulation is to get protection from the UV rays that cause the most damage. We can use organic and inorganic substances to get this protection. Organic sunscreens include oxybenzone, sulisobenzone, and bisoctrizole. Inorganic sunscreens use zinc oxide and titanium dioxide. They give good protection across the entire spectrum of UV rays.

Hair suffers a lot of damage because of exposure to the elements and the use of harsh chemicals while washing and coloring it. Color formulations might be leave-on types that help cationic film polymers bind with negatively charged amino acids on the surface of the hair. The hair colour protector formulation of high-end products typically includes an acrylic-based film designed to form polymers in combination with water.
Many-Sided Protection for the Hair Wash fastness and UV protection are major concerns for the hair colour protector formulation. You can use the dry formulation shampoo to keep your hair healthy between washes. We find film-forming polymers in the hair-styling mousse and gel formulations that improve the hair hold. Choice of Conditioning Agents There is a huge choice of conditioning agents available. You can get the best hair conditioning agent from this list: ● Silicones ● Humectants ● Proteins ● Cationic surfactants ● Oils and emollients ● Occlusives ● Polymers We can improve slickness and shine with silicones. Amodimethicone and dimethicone are popular silicone-based emollients. Surprisingly, many people prefer the use of humectants that bind and hold water. Because they are water-soluble, they won’t work well for those products that we can rinse off. Properties of Different Conditioning Agents Proteins are amino acid compounds that add to the strength of the hair. Proteins act like humectants in retaining water and as emollients to keep the surface healthy. Cationic surfactants are the best due to their versatility. They can react with negatively charged protein sites and repair damaged hair. But, they are irritating so one must use them with care. Choose According to the Hair Type The choice of the hair conditioning agent depends on the condition of the hair and other factors such as effectiveness and cost. The protection strategy of rinse-off products will work best with products whose efficacy has undergone testing. You can create a soft mass of hair with a wonderful finish by using the right product. One can also add a luxurious shine and gloss to the hair to improve its looks. |
