19.7 Applications of Natural Products in Cosmetics
Some of the natural products from the plants have been used for skin and hair
problems. For instance, different parts of these plants Rubia cordifolia, Linn.
Callicarpa macrophylla Vahl, Acacia concinna DC, emblica officinalis Gaertn, and
Curcuma longa have been used directly for face and hair problems. Ethnic and
community group’s historically natural products have been used for the treatment of
different hair conditions and skin diseases. Natural products intimate potential
properties like antioxidants, antimicrobial, anti-inflammatory, antimelanogenesis,
antihyluronidase, and antityrosinase in cosmetics. Some of natural products have
been used in different applications shown below.
19.7.1 Natural Products as Skin Care Agents
Dry skin treatment.
Stratum corneum binding of water indissoluble could be compromised and ineffective. For this reason, it is beneficial to decrease the transepidermal water loss by
applying occlusive films. Hence, there is no cause why mineral oil or petrolatum
should not be used. Hence, vegetable oils have more benefits for dry skin treatment.
Castor oil formed from (Ricinum communis) castor seeds, consists of more than
50% of fixed oil, more viscous, pure when colorless and has slight odor. Castor oil
is composed of ricinoleic acid and unsaturated fatty acids. Hence, castor oil is used
to skin smoothing, protect skin from harsh climate as well as used to prepare soaps.
Ricinolic acid and its analogs are used to improve the skin moistening and
smoothing qualities as well as enhance the skin conditions such as acne and rough
skin. Hydrogenated castor oil or its esters oils has been used for solubilizers for
toiletry as well as skin and hair care cosmetic formulations and are useful condition
and cleaning of the skin and hair (Sato 2002). Cocoa butter is used for the
smoothing of sunburn and windburn. Cocoa butter is obtained from T. cacao.
Cocoa butter composed of triglycerides consists of palmitic acid, stearic acid, and
oleic acid as well as monounsaturated fatty acid. Hence, it is widely used in
moisturizer and also used in cosmetic preparations and it has reported as potential
antioxidant (Sato 2002). Sunflower oil is composed of polyunsaturated fats,
triglycerides, or linoleic acid as well as essential fatty acids. These constituents are
used for maintaining good skin. Linoleic acid reduces the water loss transepidermal
and eliminates the scaly lesions normally with patients. Hydrated sunflower oil and
oleic acid contents are used in natural and functional raw materials in cosmetic
preparations. Olive oil is composed of triglycerides, tocopherols, squalene, carotenoids, sterols, chlorophylla, polyphenols, squalene, volatile oils, flavored compounds, and fatty acids. These constituents are useful for treatment of dry skin, as
well as used in lip balm, soap, hand lotions, shampoos and conditioners and
