Definitions

  • This patent application relates to personal care compositions, particularly to skin scrub compositions, and more particularly, to a novel use of desiccated coconut as skin scrub agent, skin scrub compositions containing desiccated coconut, method of making the skin scrub compositions containing desiccated coconut, and use of the scrub composition for exfoliating the skin.
  • the human body forms dead skin cells at the outermost and visible layer of the skin.
  • the exposure of the skin to polluted air and other harsh elements increases the formation of dead skin cells and impurities in the skin.
  • the skin becomes dry, rough, and ugly.
  • the cosmetic industry had developed a wide range of personal skin care products to keep the skin radiantly clean, healthy, and rejuvenated.
  • abrasive particles as the main scrubbing agent.

  • Sea salt scrubs have been used in Oriental Spas as a way of getting rid of impurities and exfoliate dead skin cells.
  • Fine pure sea salts are usually mixed with different kind of oils such as sunflower oil, peanut oil, olive oil, coconut oil etc. Since sea salt is insoluble in oil, it maintains its form in the saturated state.
  • the exfoliating properties is drawn from the natural abrasive texture of the sea salt together with the rubbing motion when the product is applied The coarse texture and the rubbing motion sometimes creates irritation of the skin especially when done by someone not skilled in applying the salt scrub.
  • the use of abrasive particles such as sea salt usually leaves a scratching feel, and in some cases, makes the skin dry.
  • skin scrub compositions are formulated using oils, humectants and moisturizers as the cosmetic scrub carrier for the abrasive particles.
  • aqueous scrub carrier is recommended setting aside the problem on scratching.
  • Other solutions focus on the type and size of abrasive particles.
  • US 4,673,526 the use of water-insoluble polymeric materials that breaks at low shear force has been suggested as substitute to highly abrasive materials.
  • they are still abrasive even in non-aqueous or oiiy media or emulsion.

  • This patent also teaches the use of coconut oil as a non-aqueous media. Although the use of coconut oil is suggested, the use of virgin coconut oil was not specifically mentioned.
  • CA 2,331,827 discloses the use of a specific sea salt called sodium sesquicarbonate and a mineral oil in specific ratio to reduce skin irritation, it is noted that slight skin irritation is still observed, which is attributable to the naturally rough crystal structure of the salt.
  • JP 10338625 discloses a scrub cosmetic composition that has excellent removal and massage effect, affording the skin with dampish feeling after use with slight skin irritation by including specific plant seed-ground particles in combination with powdered inorganic particles. However, skin inflation and scratching is still observed. Furthermore, the powdered particles can deposit in and block the skin pores.
  • aqueous or non-aqueous materials use either aqueous or non-aqueous materials as a scrub carrier depending on the abrasive material used. If the abrasive material is soluble or slightly soluble in water, a nonaqueous scrub carrier is used. On the other hand, for non-soluble abrasives, an aqueous or non-aqueous scrub carrier can be used. The choice of scrub carrier is also predicated on the skin type of the target user. For example, if the product is intended for oily skin type, an aqueous scrub carrier is more appropriate to use. However, regardless of the type of scrub carrier used, the problem of scratching still remains as most of these scrub compositions use abrasive materials as the scrubbing agent.

  • the desiccated coconut also functions as a filler to reduce cost of scrub compositions and increase production rate conventional scrub compositions to at least 20%. The rate increases as the amount of desiccated coconut is increased.
  • the present invention provides desiccated coconut as a soft scrubbing agent useful for exfoliating dead skin and impurities.
  • Desiccated coconut is advantageously organic and abundant in tropical countries like the Philippines. It is commercially available with varying physical and chemical specification such as size, odor, taste, moisture content, fat and fatty acid content, etc.

  • desiccated coconut with low moisture content preferably, not more than 3%, to ensure a longer sheff life especially when no preservatives are added.
  • the moisture content of the desiccated coconut is above 3%, it is preferable to add preservatives to ensure a longer shelf life for the scrub agent and the scrub composition.
  • Food grade desiccated coconut that is commercially available normally has a fat content of not less than 55% and a fatty acid content of about 0.3%, as [auric acid.
  • the fat content of desiccated coconut is not really critical to the invention. In fact, any amount of fat content may be acceptable for use ⁇ n this invention.

For example, when aqueous scrub carrier is used, the use of preservative is a must to avoid rancidity and to extend shelf life. On another note, the aqueous scrub carrier may have to be thickened to prevent the desiccated coconut and abrasive particles, when present, from settling down the bottom of the container. Since aqueous scrub carriers tend to dry the skin, humectants may also be added, in sum, the scrub carrier may be in the form of liquid, gel, or cream.
