Definitions
- This invention relates to low residue deodorants in the form of solid sticks or gels, which are based on dibenzilidene sorbitol (DBS) as a gellant and a polyhydric alcohol such as propylene glycol (PG) as a solvent in combination with a selected dimethicone copolyol ester soluble in propylene glycol (PG).
- DBS dibenzilidene sorbitol
- PG propylene glycol
- This invention relates to the use of these materials as anti-tack agents in combination with micronized zinc oxide and fragrance in deodorants formulations.
- Dibenzylidene sorbitol also called dibenzaldehyde monosorbitol acetal, or dibenzyl monosorbitol acetal or dibenzylidene monosorbitol acetal
- derivatives thereof such as those which are substituted on one or both of the aromatic rings with a fluorine or methoxy group and those which have the sorbitol portion replaced with other reduced sugars such as xylitol or ribitol as described in U.S. Patent 5,609,855 assigned to Procter & Gamble
- DBS dibenzylidene sorbitol
- DBS dibenzylidene sorbitol
- dibenzylidene sorbitol is stable in alkaline or neutral media, such compounds are not stable in acidic media.
- acidic environment such as in the presence of acidic antiperspirant materials, and in the presence of even small amounts of water, the dibenzylidene sorbitol deteriorates and breaks down.
- the use of DBS sometimes causes problems in the aesthetics of cosmetic products or problems with structural properties. Accordingly, there is a need to find a way to form products containing DBS which are stable and which have acceptable aesthetics.
- DBS in an antiperspirant formulation requires the inclusion of polyhydric alcohols such as propylene glycol as a solvent if a clear, transparent product is desired.
- polyhydric alcohols such as propylene glycol
- the high propylene glycol content when combined with aluminum salts which are included in antiperspirant compositions for wetness control, contribute to undesirable tackiness or a sticky feel for these products when applied to the axilla region of the body.
- Clear antiperspirant sticks were first formulated with DBS in the late 1970's. Since then there have been continued technical efforts to reduce the negative sensory attributes. Some of these efforts have focused on alternative solvents to replace a portion of the propylene glycol with organic esters known in the art as emollients. This creates a further problem since many of these emollients are either unsafe for personal care products or do not achieve acceptable aesthetics.
- Silicone fluids such as cyclosiloxanes (for example, DOW
- CORNING® 244 and 245 Fluids are used in some major commercial products. Silicone fluids are used because of their low tackiness, superior glide and skin- feel properties. However, silicone fluids are difficult to introduce into DBS based cosmetic stick products such as antiperspirants because they are not good solvents for DBS and they are not readily compatible with propylene glycol and many organic esters or emollients.
- United Kingdom Patent GB 2 280 111 assigned to Union Camp Corporation describes a gel stick composition comprising a dihydric alcohol as a primary solvent, a co-solvent such as low molecular weight polyethylene glycol, water and/or glycerine, a buffering agent and DBS as a gelling agent.

- compositions of the present invention have less tack than conventional cosmetic sticks. Tack can be evaluated by various techniques including the Forearm Flex Test.
- Forearm Flex Test In this test the administrator first over-wraps the test products to hide their identity from the panelists and then gives each sample a code number to hide their identity from the statistician who will analyze the data. These precautions are done to avoid bias of the panelists and the test evaluators. Next, one of two products is applied to one arm at the crease of the elbow and the second product is applied to the same area of the other arm. The two products are applied in a similar manner. Product application is done by either counting the number of strokes or by weighing the products to be tested before and after. Products are applied in random fashion to eliminate left-handed or right-handed biases. The ambient room temperature and humidity are recorded.
- the panelists evaluate the tested products for several aesthetic attributes including, but not limited to, wetness, oily/greasy feel, glide, and, most importantly, tackiness/stickiness.
- Control Data analysis using a statistical software package called JMP from SAS Institute (Cary, North Carolina) permits identification of products, which are significantly different from the Control sample.
- the Control is selected to be a competitive benchmark currently in the marketplace, which represents what is believed to be the best commercially available standard.

- the zinc oxide pre-mix is heated to a temperature of at least 90 degrees C.
- Stearyl alcohol is weighed out and added to the main mixture once the mixture is clear. Note that if DC 2501 is used as an emollient, preheating of this material is done to melt it first before addition to the mixture. Mixing is continued until the solution is again clear. The emollient is weighed out, added to the main batch, and mixing is continued until the solution is clear. The batch is cooled to 100 degrees C.
- the zinc oxide pre-mix is slowly added to the batch and mixed until the mixture is uniform. Fragrance is added to the main batch and the mixture is quickly cooled to 90-92 degrees C.
- the mixture is then quickly poured into the appropriate containers, for example, containers having dimensions of 3 cm (width at widest part of oval) X 6 cm (length of base) X 10 cm (height). If an emollient is added to the main batch shortly after the stearyl alcohol addition, the temperature drops close to 100 degrees C, so a slight adjustment may be needed to maintain the temperature at 105 degrees C.
- EXAMPLE 2 As a general procedure for making deodorant creams, the following procedure can be used. Propylene glycol is weighed out into a main container. Hydroxypropyl cellulose is weighed out and sprinkled into the main container with high shear mixing at room temperature. Tripropylene glycol and a dimethicone copolyol ester (SILWAX WSL) are each weighed out and each added to the main mixture. The DBS is weighed out and gradually added to the mixture with high shear mixing. Mixing is continued at room temperature for 10 minutes with high shear stirring but no splashing. A suspension of the zinc oxide propylene glycol is made as a separate pre-mix.
- SILWAX WSL dimethicone copolyol ester
- DC 2501 is used as an emollient
- preheating of this material is done to melt it first before addition to the mixture.
- Mixing is continued until the solution is homogeneous.
- the emollient is weighed out, added to the main batch, and mixing is continued until the solution is homogeneous.
- the zinc oxide pre-mix is slowly added to the batch and mixed until the mixture is uniform. Fragrance is added to the main batch.
- the mixture is then quickly transferred into the appropriate containers, for example, jars or squeezable tubes.
- Example 3 The method of Example 1 can be used to make a stick with the following ingredients: 56.75% propylene glycol; 2.0%> DBS; 10.00%) dimethicone copolyol ester (SILWAX WSL (L7382A); 5%> zinc oxide with an average particle size of 60 nanometers (NANOXTM) with q.s. propylene glycol; and 1.25% fragrance.
- SILWAX WSL dimethicone copolyol ester
- NANOXTM average particle size of 60 nanometers
- fragrance 1.25% fragrance.
- Example 4 The method of Example 1 can be used to make a stick with 1% of the dimethicone copolyol ester; 3% zinc oxide (NANOXTM zinc oxide); 51% propylene glycol; 6.25% dipropylene glycol; and 3.75%o tripropylene glycol; 2.5% DBS; and 1%> fragrance.
