Diethylenetriamine pentamethylene phosphonate sodium is an organophosphorus series scale inhibitor. Its molecular formula is C9H28O15N3P5, and its relative molecular weight is 573.2. Diethylenetriamine pentamethylene phosphonate sodium is non-toxic, miscible with water, has better scale inhibition and corrosion inhibition effect, and has good temperature resistance, which can inhibit the formation of carbonate, sulfate and phosphate scale. Especially when the pH value is 10-11, calcium carbonate still has a good scale inhibition performance, and the scale inhibition effect at this time is 2 to 3 times higher than that of hydroxy-ethylenediphosphonic acid and amino trimethylenephosphonic acid. Another outstanding feature is that the combination with manganese ions has a good corrosion inhibition ability on carbon steel and copper alloys.

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.
