Definitions
- the present invention relates to an anti-acne composition. More particularly, the present invention relates to an anti-acne composition having sunscreen properties or having a high sunscreen protection factor (SPF).
- SPDF sunscreen protection factor
- Acne can be a problem faced by many people, particularly during the teenage years. Acne is a condition where oil glands of the skin can become clogged, forming spots, pimples and sometimes cysts. Although acne is not a dangerous condition, it can lead to scarring of the skin. Further, because acne typically appears on the face, it can cause significant self-esteem issues, particularly in developing young adults.
- Some topical acne treatments include keratolytics. These compositions are peeling agents that can be used to treat acne by unblocking skin pores. A number of these types of anti acne compositions include salicylic acid as an active agent.
- Retinoids are also used in acne treatment. These are very effective and work by unblocking skin pores, reducing the amount of oil that is produced by the sebaceous glands in the skin and reducing inflammation. These compounds can cause severe birth defects and therefore cannot be taken by pregnant women, those planning pregnancy or women who are not using appropriate contraceptive measures. These compositions work very effectively but can cause greater amounts of skin irritation than other topical acne compositions.
- Acne compositions typically include a number of ingredients, with the active ingredients being fairly aggressive and reactive chemicals. As a result, changes to the
- compositions can cause unexpected effects.
- sunscreen compositions that are promoted as being suitable for use by acne sufferers. There is a consensus that use of sunscreens will cause blockage of skin pores, which is likely to exacerbate acne. Some companies promote sunscreens that are oil free and will not clog pores, with these sunscreens being further promoted as being suitable for use by sufferers of acne.
- the present invention is directed to a composition for treating acne, which may at least partially overcome at least one of the abovementioned disadvantages or provide the consumer with a useful or commercial choice.
- the present invention in one form, resides broadly in a composition for treating acne, the composition comprising an anti-acne active agent including salicylic acid, an emulsifier, an emollient, particles of zinc oxide, water and a humectant, the composition having a sun protection factor (SPF) of at least 5.

- the present invention also relates to a method for preparing an anti-acne
- the present invention provides a method for preparing an anti-acne composition, the composition comprising an anti-acne active agent including salicylic acid, an emulsifier, an emollient, particles of zinc oxide, water and a humectant, the method comprising a) combining the anti-acne agent, the emollient and the emulsifier and mixing at an elevated temperature to obtain a homogenous mixture, b) adding the particles of zinc oxide to the mixture from step (a) and stirring to obtain a mixture, c) mixing water and the humectant and adding the water and humectant to the mixture from step (b) with stirring, and d) cooling to room temperature whilst maintaining stirring.
- an anti-acne active agent including salicylic acid, an emulsifier, an emollient, particles of zinc oxide, water and a humectant
- step (a) is conducted a temperature of from 70°C to 90°C, or from 80°C to 85°C.
- Steps (b) and (c) may be conducted at the same temperature as a step (b). In other words, the temperature of the mixture is maintained during steps (c) and (d).
- salt and preservative are mixed with the humectant and that mixture is subsequently mixed with water in step (c).
- Step (b) may involve adding the particles of zinc oxide to the mixture from step (a) under vigorous stirring.
- step (c) may involve very slowly adding the mixture of water and humectant (and optionally salt and preservative) to the mixture from step (b).
- the mixture of all ingredients resulting from step (c) is homogenised by further mixing to obtain a homogenous mixture.
- a composition was made from the following ingredients:
- the composition was prepared by combining a sensory modifier, anti-microbial agent and salicylic acid to an amount less than 4% by weight, with the ingredients of phase A .
- the combining ingredients were heated to 80 - 85°C with stirring until all components were molten/dissolved.
- Phase B was added to the phase A mixture with vigorous stirring, whilst maintaining temperature.
- the humectant, preservatives and salt were mixed together to an amount less than 6% by weight.
- Water was added to that mixture with stirring until all components were fully dissolved to form phase C.
- Phase C was very slowly added to the mixture of phases A and B with intensive stirring, whilst maintaining temperature.
- the resulting mixture was then homogenised for one minute per 100 g of mixture.
- the mixture was cooled to room temperature whilst undergoing vigorous stirring during cooling.
- composition set out above was tested and found to have an SPF of at least 30. It is expected that the composition will demonstrate effective treatment of acne in a number of patients.
- the present inventors are not aware of any existing anti-acne compositions that have a high SPF factor and can therefore also function as a sunscreen. Indeed, conventional thinking in this art is that sunscreens exacerbate acne because sunscreen tends to block the pores of the skin. In contrast, most medical practitioners believe that the pores of the skin should be cleared in order to properly treat acne. Further, anti-acne compositions typically contain a number of quite aggressive chemicals and the interaction of those chemicals with other compounds can be unpredictable. Indeed, the present inventors took in excess of 2 years of experimentation to arrive at a composition that is effective in treating acne, has a good SPF rating and is stable with a reasonable shelf life.
