Vitamin C is an antioxidant that we ingest through our diet and is one of the most widely used skin care treatments due to its properties to combat premature skin ageing. Fruits and vegetables are the main sources of this vitamin: kiwis are one of the fruits with the highest Vitamin C content, followed by…
An even skin tone is usually associated with healthy skin. In contrast, skin subject to premature aging caused by UV light (photoaging) experiences an increase in the production of melanin, the pigment controlling skin colour. And this results in the appearance of skin spots. History and origins In ancient Egypt, as well as in…
Water is a vital element for our body to function properly. About 20% of the body’s total water is found in the skin (dermal and epidermal layer). It is necessary to keep the skin in its optimal state of hydration in order to maintain the skin’s elasticity and for it to establish a correct barrier…
What are the effects of sunlight on skin? Visible sunlight covers the wavelengths from 400 to 780 nm, and is a small part of the entire spectrum of radiation emitted by the sun. So-called infrared radiation corresponds to wavelengths longer than 780 nm, while ultraviolet radiation is defined as having a wavelength shorter than 400…
Sustainability is about promoting economic and social progress while respecting natural ecosystems and the quality of environment. The consumption of products whose raw materials come from renewable or natural sources, and which are readily biodegradable, is commonplace. Alkylpolyglucosides (APG) are sustainable surfactants that meet these characteristics and are suitable for the EU-Ecolabel. Alkylpolyglucosides (APGs): the…
What is an emulsion? Emulsions are mixtures of polar and non-polar liquids, and cosmetics are full of formulations combining an aqueous phase with oily ingredients. What is an emulsifier for? In order for these mixtures to remain stable, emulsifiers must be incorporated. Thanks to emulsifiers, aqueous and oily phases, which are immiscible, can be…
When developing sulfate-free shampoos, the main challenge faced by the formulator is to achieve foaming and viscous products. The selection of sulfate-free surfactants is essential to achieve high performance products. Surfactants Surfactants are essential components in cosmetics. From body hygiene to skin moisturising cosmetics, and even tooth and nail care products, surfactants are found…

BC is an Italian company that has emerged from its experience in cosmetics and human food, dedicated to the manufacture of products for cosmetics, and with a strong commitment to innovation in the sector. It has a subsidiary company, CR&D, oriented…
Prolonged exposure to ultraviolet rays is the major cause of skin damage, leading to injury and premature aging. Photons from solar radiation activate a chain reaction that leads to the interaction of free radicals with proteins and lipids. In cosmetics several strategies are followed to fight against the damage produced by solar radiation, one of…
Surfactants are present in a wide range of cleaning products, and one of the usual groups is anionic surfactants, which are particularly valued for their foaming ability. There is a multitude of anionic surfactants for use in detergents, although the most commonly used today are the salts of dodecylbenzenesulfonic acid and ethoxylated sodium lauryl sulfate.…
