Lactobionic acid is a compound composed of lactose and glucose, belonging to a type of bionic acid. It has strong acid neutralizing ability and metal ion chelating ability, and has antioxidant and moisturizing properties.
Lactobionic acid is often used in skin care products.
Lactobionic acid has various functions and benefits in skin care products as follows:
1. Antioxidant effect: Lactobionic acid is a powerful antioxidant that can neutralize free radicals and resist oxidative damage caused by environmental pollutants and ultraviolet radiation. Antioxidant action helps reduce oxidative stress in the skin, preventing the appearance of signs of aging such as wrinkles and fine lines.
2. Moisturizing effect: Lactobionic acid has excellent moisturizing ability. It attracts and locks in moisture and maintains the skin's moisture balance, thus keeping the skin elastic, supple and hydrated.
3. Exfoliation and skin regeneration: Lactobionic acid is a mild fruit acid that can effectively remove dead skin cells on the stratum corneum and promote horny renewal. Not only does this improve skin texture and even skin tone, but it also stimulates the production of collagen and elastin fibers, accelerating the skin cell regeneration process.
4. Anti-inflammatory and repairing: Lactobionic acid has anti-inflammatory and repairing effects, which can reduce skin redness, tingling and allergic reactions. It helps soothe sensitive skin and promotes the repair and healing of damaged skin.
5. Brighten skin tone: By promoting cell metabolism and removing aging cells on the surface, lactobionic acid can improve uneven skin tone and make skin brighter and smoother.

Introduction
Homosalate CAS 118-56-9 is an organic compound used in some sunscreens. It is made by the Fischer-Speier esterification of salicylic acid and 3,3,5-trimethylcyclohexanol, the latter being a hydrogenated derivative of isophorone. Contained in 45% of U.S. sunscreens, it is used as a chemical UV filter. The salicylic acid portion of the molecule absorbs ultraviolet rays with a wavelength from 295 nm to 315 nm, protecting the skin from sun damage.
Application
The primary application of Homosalate is in sun care products such as sunscreens, lotions, and moisturizers to provide protection against damaging UV rays.
1. Octocrylene is a UV-B filter that is approved in the USA, Europe, and Japan for use in sun care preparations.
2. Octocrylene is miscible with many cosmetic oils, it can easily be incorporated into the oily phase of an emulsion
3. Octocrylene is hydrophobic and oil-soluble, it is preferred for water-resistant and water-repellant formulations octocrylene is also compatible with all common plasticizers.
Function & Application
Octocrylene is a UVB sunscreen with strong water-resistant properties and a rather broad-band absorption range. It exhibits good photostability and is being evaluated by many companies as an effective SPF booster and waterproofing enhancer.
This is an expensive ingredient with an approved usage level of 7 to 10 percent in both the United States and the European Union. Although gaining in popularity among formulators, its cost and usage level can limit use. In addition, some studies are indicating it may cause allergic reactions in the skin with a history of photoallergy.
Use:
Octocrylene is chemically related to cinnamates. It can be used to boost SPF and improve water resistance in a given formulation.
Octocrylene is photostable and can improve the photostability of other sunscreens. It is expensive and can present difficulties in the formulation.
2-Ethylhexyl Salicylate, or octyl salicylate, is an organic compound used as an ingredient in sunscreens and cosmetics to absorb UVB (ultraviolet) rays from the sun. It is an ester formed by the condensation of salicylic acid with 2-ethylhexanol. It is a colorless oily liquid with a slight floral odor.
The salicylate portion of the molecule absorbs ultraviolet light, protecting skin from the harmful effects of exposure to sunlight. The ethylhexanol portion is a fatty alcohol, adding emollient and oil-like (water resistant) properties.

Introduction
Betaine Salicylate is a mild BHA (beta-hydroxy acid), specifically a salicylic acid derivative. It is primarily extracted from sugar beet and has a gentler exfoliating action compared to traditional salicylic acid. It is often preferred in skincare products because of its lower irritation potential while still delivering effective results.
Function
Exfoliation: It works as a keratolytic agent, meaning it gently removes dead skin cells from the surface of the skin, unclogging pores and preventing acne formation.
Anti-Inflammatory: As a derivative of salicylic acid, Betaine Salicylate possesses anti-inflammatory properties that can help soothe redness and inflammation associated with acne and other skin irritations.
Oil Regulation: By regulating sebum production, it helps to control oily skin and prevent clogged pores, thereby reducing the occurrence of blackheads and whiteheads.
Application
Acne Treatment: Betaine Salicylate is commonly found in acne-fighting cleansers, toners, serums, and spot treatments where it targets pimples, blackheads, and whiteheads.
Anti-Aging: Its gentle exfoliating nature makes it suitable for incorporating into anti-aging products as it encourages cellular turnover, which can lead to a smoother, more radiant appearance.

Tungsten is a metallic element with the symbol W and atomic number 74, belonging to the VIB family of the sixth cycle in the periodic table. Tungsten is mainly a hexavalent cation in nature, with an iron radius of 0.68 Ã?? 10-10m. Due to the small radius of W6+ions, high electricity price, strong polarization ability, and easy formation of complex anions, tungsten is mainly in the form of complex anions [WO4] 2-, which combine with cations such as Fe2+, Mn2+, Ca2+in the solution to form precipitates of wolframite or scheelite.
