The 100% Organic Cotton pHactor
What Exactly does that Little pH Mean?
Your skin is regulated by pH, a factor that you may recognize based on the many feminine care products, creams and cleansers designed to balance the pH levels of your skin, currently sitting in your bathroom cabinets. pH is the “measurement” unit of the degree of acidity of the skin, which varies from 1 to 14 and may depend on other factors, including age, gender and parts of the body.
A pH of less than 7 is acidic while above 7 indicates the pH is basic or alkaline. If the pH equals 7, it is neutral. The pH of the skin is based on the thin film that covers the external surface of the body, a kind of water and sebum emulsion, commonly known as the natural fat secreted by the sebaceous glands.
The skin, which has an average pH of 5.5, produces this slightly acidic sebum secretion, which makes the skin soft and protects it from external agents and from micro organisms. The degree of acidity of the skin varies depending on the individual; the pH of the skin may change on the basis of the body region considered, the season, the sex, the phases of the menstrual cycle, cosmetics and detergents used, the resident bacterial flora and the degree of sweating.
Sweat is mainly used by the body for thermal regulation and is composed mainly of water and organic and inorganic substances, including ammonia and lactate, which not only alter the pH, but also give an intense and persistent odor to sweat. Excessive sweating accompanied by a pungent odor may be due to high stress, hormonal fluctuations, unstable emotional states, but also by poor diet. The sweat produced by the sweat glands, consisting mainly of water and minerals, in itself does not smell, rather the problem occurs when it comes into contact with air. In this case the bacteria present on the skin begin to multiply and produce acids that generate stenches! While a pH level of your scalp may be 4.0, the pH of your armpits may be 6.5.
The acidity of the skin’s pH is related to the presence of the hydrolipid film and the plurality of the biochemical processes that occur in the skin. The pH level of the skin also involves a person’s sweat, the substances dissolved in it (minerals, lactic acid, urea, ammonium) and water loss due to perspiration.
