Why is pH important in body and skin care products?
Human skin has an "acid mantle," a micro-thin protective shield produced by the skin's oil glands, which ensure that the skin's proper pH balance is maintained.
When an alkaline substance comes into contact with the skin, this natural, delicate balance is lost. The acid of the skin becomes neutralized, causing the skin to feel taut, dry, and uncomfortable.
Oil glands react to this over-alkalinity by secreting moisture (called 'sebum') through the pores, to try to re-balance the pH.
This results in oily skin, pore-clogged skin (when sebum is exposed to air, it hardens and darkens, causing 'blackheads'), or pores that close up completely (causing pimples). Nearby skin can become flaky, parched, and can look prematurely aged.
Without its acid mantle, skin is left exposed to the hazards of wind, sun, or environmental and bacterial impurities. Correct pH helps skin to remain protected, clean and healthy, so the skin cells can breathe as they should.
Not only does goats' milk in soap help to maintain correct skin pH, but it contributes additional moisturizing cream to skin and hair cells.
Unlike cows' milk which must be mechanically homogenized, goats' milk is already homogenized in its native state. Goats' milk molecules are comparatively smaller than those of cows, being composed of short-chain fatty acids with smaller-sized proteins. This makes goats' milk more accessible for absorption into the skin.
Goat's milk is more digestible in the intestines when it is ingested as food, for the same reasons. The short-chain fatty acids break down six times faster than cows' larger, long-chain fats.
This, in conjunction with the unique acidic content and the structure of its component fats, makes goat's milk a viable choice for people who either have allergies to usual dairy products, digestion difficulties, or highly sensitive skin.
Goats' milk soap is a natural, organic by-product of non-commercial farming, and is a productive and ethical use of surplus milk during the milking season.
Goats' milk soap helps maintain correct skin pH, is a rich, natural moisturizer, bringing with it restorative vitamins, minerals and proteins, and is gentle on even very sensitive skin.
Goats' milk soap remains a natural choice for skin care, from ancient times to our own.
