Whey Filtrate is a byproduct derived from whey, the liquid remaining after milk has been curdled and strained during the cheese-making process. This ingredient is sometimes referred to as milk serum or milk permeate in the cosmetic industry. Chemically, whey filtrate is rich in proteins, lactose, vitamins, and minerals, making it a nutrient-dense component.
Historically, whey has been used for centuries in various forms, primarily in food and dietary supplements due to its high nutritional value. Its transition into the cosmetic world is relatively recent, driven by the growing interest in natural and multifunctional ingredients. The skin-conditioning properties of whey filtrate were discovered through research into its effects on skin hydration and elasticity, leading to its incorporation into skincare formulations.
The production of whey filtrate involves a meticulous process of removing insoluble matter from whey. This is typically achieved through filtration techniques such as microfiltration or ultrafiltration, which separate the desired soluble components from the insoluble ones. The resulting filtrate is then purified and sometimes concentrated to enhance its beneficial properties for cosmetic use.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Whey Filtrate:
Whey Filtrate is primarily known for its skin conditioning properties. This means it helps to maintain the skin in good condition by improving its appearance and texture. When used in cosmetic formulations, Whey Filtrate can help to soften and smooth the skin, making it feel more supple and hydrated. This is particularly beneficial for those with dry or rough skin, as it can provide a more even and healthy-looking complexion.
Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).
Whey Filtrate is generally considered safe for topical use in cosmetic products. However, as with any ingredient, there are potential side effects and considerations to keep in mind.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Whey Filtrate during pregnancy are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice before using products containing Whey Filtrate.
Side effects and adverse reactions from Whey Filtrate are relatively uncommon, but they can occur. It is recommended to perform a patch test before widespread usage to ensure there is no adverse reaction.
Whey Filtrate has a comedogenic rating of 1, which means it is very unlikely to clog pores. This makes it a suitable ingredient for people prone to acne, blemishes, or breakouts.
